old thread here, 1. Basic overview of Virtualization 2. Research and learning material 3. Terminology and Liscensing 4. Different Virtualization Companies, differences ect 5. Common Virtualization Techniques (Best practices, network set ups, Allocation of resources) 6. Misc  This will be primarily VMware/HyperV, I haven't worked with citrix enough to give a good rundown on everything citrix. If you feel confident and want it that badly please post about it 1. Basic overview of Virtualization Keeping it pretty basic it will get more in depth later on, if you want check out the old threads OP at the top of the page. Q: What is virtualization A: Virtualization is the process of divvying up physical host resources for multiple operating systems to run on at once. Q: How does that work A: By use of a HyperVisor which we have two kinds. Bare metal, Meaning you install the hypervisor directly onto the physical host and let it schedule resources and use it pass it up to the virtual machine. Common ones are Citrix and Vmware and Hyper-V SPECIAL THANKS TO Syano!!! Host based, You install this hypervisor just like a program in windows/linux it manages VM's by going through the OS and software layers Q: Which is better? A: It depends really Vmware is best for performance and features, but has some tighter hardware requirements than something like Hyper-V. Using Bare metal you will get better performance and have access to more resources, EXSi is completely free too. So if your hardware checks out I would recommend ESXi as you can run hyper-V on top of ESXi. Q: Who makes virtualization A: The big players are Vmware, Citrix and Hyper-V Q: Who uses it? A: Amazon, apple, MS, Redhat, all the big named companies are on virtualization now. Q: Other than the host what are good things to know for Vmware A: Networking and storage Q: Why would I choose to virtualize my company A: Lots of reasons, >No hardware dependencies Let's say a host goes down in the middle of the night, with VMware it can restart the Server on a new host without ruining your SLA's or you even knowing until you come in >Cost savings You don't have to go 1:1 physical box to server, it is possible to have a hundreds of servers + data center + high uptime environment in a very small area that is easy to cool and doesn't cost as much to build >Automation VMware has a nice reporting feature that helps you monitor performance across your servers, so instead of having hundreds of reports print out from windows/linux/BSD you now can set rules so if a host is using 95% CPU it emails you which VM, where it is at and what the problem is, now you just give it more resources or look into what service is causing greif >Snapshots gently caress up an update that is causing your servers to be unresponsive? Snapshots can roll back to a running server prior to updating so you are back up and running. >Over provisioning I can assign a VM 1TB drive if I only have 500GB and it will be fine, ofcourse when it starts filling up you will need to watch it and vmotion it to something with more resources ---I'll add more when I see the need to--- 2. Research and learning material  This will cover learning more about VMware and Hyper-V! Certs, learning VMware for the first time, or just to learn more look here!!!:fsiren: New to Vmware/hyper-v, Want to go for the VCP, or just need to get more into it? ORDER THE Vsphere 5 BOOK FROM SCOTT LOWE Seriously I can not even being to say how good this book is for learning, even if you are a noob or feel pretty confident with it this book will still teach you alot Masting hyper-v Like the mastering server 2008 book but only about hyper-v Want to learn how to script things, automate things, or do everything from vCLI? Power CLI book is for you I need to learn how to HA/DRS/Storage DRS work in detail! vSpher 5 Clustering book is for you! this is just like the yellow book for 4.1 My company is going virtual, next year and they want me to plan it all![/b] vSphere Design is the book you might want I need to know storage AND networking? EMC book and Cisco book will give you good working knowledge of the two areas I want to learn this stuff hands on! How do I achieve this? Your best way is to either get some cheap servers off ebay Save My Server generally has good deals Or better yet max your PC out with 32/GB ram and a 6/8core CPU and SSD to hos a whole cluster  That cost me around 500-550 for 32GB ram, mobo, x6, 256GB SSD, and is alot more quite than running 5 servers, I run quite a few machines at once no slowdown as the VM's are on an SSD. Sorry had to extend my  I am using Vmware workstation as I got it free from my school, it cost ~200, 100 if you are a student dollars but things like Virtual box or Vmware player or the trial of workstation 8 for 30 days Workstation 8. like I am doing you can run ESXi inside a VM, and run VM's on that hypervisor(32bit only in 7, 8 supports 64 inside 64), 3 hosts(can add more), Vcenter Enterprise plus, hosting about 10-15 VM's with ease. I need Hyper-V!! If you don't feel like reformatting you will need to look into one of the host based hypervisors posted above, like virtual box and install windows server 2008 R2 and go from there, not sure if virtualbox supports nesting so you may have to use 2008 and 32bit OS's in hyper v. You can download server 2008r2 here  Wait if I want to get VCP certified I have to go to a class?Yes, to keep the cert value high and at least give people who did brain dumps some understanding of it you need to attend a VMware 5 day course or much cheaper option of looking into a local CC for it. You can tell if the school is qualified by asking them or looking on this list here or here Not all schools are fully qualified to teach to take the VCP and VCAP mine is qualified for both so make sure you check. Generally it is cheaper to go to a CC for it, most schools give you a voucher cutting the exam down to 75bucks and online academic resourses IT SAYS MY HARDWARE ISN'T SUPPORTED!!! Check to make sure intel-VT/amd-V are enabled in the bios and make sure they are on the HCL . NOTE that just because it isn't on the HCL doesn't mean it won't work, you can get 5 working stable on non HCL stuff but VMware/HP/Dell will not offer assistance performance isntability 3. Terminology/Licensing There is alot of terminology that VMware gave itself, I'll try to give you the best overview on the most common terms ESXi - The name of the hypervisor by VMware, also refereed to as ESX which while it is its own product the last build was ESX 4.1 there is no 5 planned Vsphere Client - The program used to manage ESXi hosts remotely vCenter - Links multiple hosts together in one easy to see manipulable resource MOST OF THESE BELOW REQUIRE VCENTER HA - High Availability allows virtual machines that go down to be automatically restarted without user interaction DRS - Distributed Resource Management, This allows Vm's to be started up or moved onto different hosts allowing for load balancing across the cluster DPM - Distributed Power Management, When hosts go to low load states DPM will shut down hosts/machines and migrate them to other hosts saving power (iLo must be supported on the host for this) vMotion - Allows for live migration from one host to another host without downtime to the VM running Storage vMotion - Allows the virtual disk and configuration files to move from one Datastore to another FT - Fault tolerance, allows for a VM to run on 2 different hosts at the same time, if one host goes down the other one takes over, little to no downtime. This is different than HA as HA does a restart FT keeps the machine running vSwitch - a internal switchin the esxi kernal allowing for virtual network traffic to pass from the vm to other VM's or to a NIC SMP - Term for how many cpu's the VM can access VDswitch - Virtual distributed switch, allows for layer 2 support on virtual networking and consolidation of networking across the cluster Host Profiles - Think of these as unattend files in windows, basically you can have everything a new host needs, set network adapter IP's, storage, NTP settings, HA/DRS, you name it, in about 5 clicks HBA - Host Bus Adapter, kinda self explanatory Resource pool - a way to further divvy up resources among a ESXi host/cluster, generally used where resources are low and contention is obvious Ballooning - A technique used to reclaim unuesed guest memory to keep the host from swapping pages to disk ___Storage/Netowrking___ reworked NFS - Network File Share, VM's will be stored on these shares and accessed over the network. This method is easy to maintain, it really is as simple as making \\server\share and then adding it to the data stores. After that you are done! NFS is file level not block level meaning when it needs to access the file it puts a small lock on it momentarily this can hurt performance but on most setups you won't notice it much other than latency is a smig higher. More about file locking http://en.wikipedia.org/wiki/File_locking ISCSI - Block Level, data stores are mounted and accessed via targets and initiators a bit more difficult to set up, but offers things like CHAP, no file locking, MPIO, Lun masking, and smig lower latency. FCoE - uses the Fibre Channel WWN protocols over Ethernet instead of... Fiber! much faster than Iscsi since it does not have a TCP/IP overhead, speeds range from 4-10Gb/s latency is much lower, costs a bit more. Fibre Channel(FC) - Runs over Fibre Thin Provisioned - Disks are only the size the OS asks for, 1TB disk with 10Gb storage will only be 10GB Thick Provisioned - Files are Zero'd out performance is faster than thin, SQL servers will need this Raw Device Mapping - The raw LUN is presented to the Guest VM and offers the best performance for that VM Which should I use?[url]http://www.youtube.com/watch?v=VO46FyxGf3M]An EMC guy gives a good overview worth the watch [/url] It fully depends on your environment, generally NFS will perform neck and neck with iscsi in terms of throughput/IO, and gets a nice gain with jumbo frames, and is really easy to administer and trouble shoot do to the simplistics of it. Iscsi while it is a bit more difficult to set up offers CHAP which helps increase security, offers a tad lower latency, and MPIO. I generally tend to go for iscsi just for the lower latency and chap support, spending an extra 5 minutes to set it up is worth it, but not all environments need 10ms latency vs 5ms latency and Chap support. In short both offer about the same performance when configured properly, so it really comes down to if you need the small nitty gritty things that each have over the other.  OH NO WHICH ONE DO I GET!!! http://www.vmware.com/products/datacenter-virtualization/vsphere/small-business/compare-kits.html I thought there was a free one There is just the standalone hypervisor ESXi 5, but you have to manage each host individually. WHAT? I can't use all my ram? What is that! http://www.vmware.com/products/vsphere/pricing.html The Stand alone hypervisor allows you to use all the hosts ram I believe, as long as it isn't clustered Explained Let's use the Essentials Plus kit, you have 3 hosts total, each with dual socket CPU's, each of those CPU's can address 32GB total, so if you have a VM with 32GB ram, the CPU can not run any more VM's. While this may be a turn off at first but as long as you provision things correctly you should have no trouble. Generally I have my Servers running at 60-65% idle 75-85% load. If say a Mail/web/other server uses 2.5GB ram when low load and 3.5GB during peak I would assign it only 4GB, as unused ram is wasted ram. 4. Different Virtualization Companies, differences ect I know I will get a lot of  here this is a general overviewVMWARE Vmware probably is usually regarded to as the leader of virtualization, has the best market share and most features(that works most of the time anyways). Vmware probably costs more and is a bit more picky on hardware support, but the stuff they sell is rock solid. Generally most of the modern servers are supported, I haven't seen any dells that have not been on the support list 2950 and up. I would generally pick VMware if a client of mine needs up time and stability. Vmware server is a dead host based hypervisor vmware offered up till Jan 2010 Hyper-V Microsofts take at virtualization, cluster-able and easy to use. Comes free with server 2008(ESXi is also free), feels like any other host based hypervisor, if you use windows 7 mode or vmplayer this will be vary familiar, Hyper-V 3.0 is coming out with windows 8 and promises to offer some decent features we'll just have to wait and see. This is a good cheap solution if your hardware is older and not on the HCL or first time virtualizing this is a good choice. Citrix Bare metal, a lot like VMware only I hear lots of horror stories regarding the instability, I really don't use citrix due to bad past expirences with them, but they are much cheaper than VMware and offer features like vmware does HA/DRS/FT they just have different names and act slightly different. If anyone wants to give there .02 on this feel free, I do hear Citrix VDI solution is much better than Vmwares, but then again we have Windows Terminal Server for a reason.  Which is right for meIt depends on your environment really First time virtualizing, no budget, or small infrastructure to virtualize?? Chances are you have a windows 2008/2008r2 server on site, hyper-v is simplistic, somewhat clusterable, and included in your server. The other option would be convert the physical host to a vm using Vmconverter, install ESXi 5 installed onto the server and import the VM's and you are done! Too many servers need to consolidate, uptime is the game, or want to use the most of your hardware? Citrix of Vmware would be the best, for small businesses I would recommend the Essentials Plus kit is a good place to start, anything more Enterprise or Enterprise plus Large environment 99.99% up times, need to make sure each vm has a nice host? Enterprise or enterprise plus, preferably plus but that all depends on your budget an needs, Storage DRS is amazing and only in + if anyone wants to add citrix stuff here feel free 5. Common Virtualization Techniques (Best practices, network set ups, Allocation of resources) Now that you have an overview of Virtualization let's look more into the setups, I will mostly be addressing Vmware/Citrix here, some of the things apply to hyper-v as well but not as much In a virtual environment you want to keep out Single Points of Failure (SPoF) and make things as modular as possible, if set up correctly you can do a Virtual environment server upgrades and network upgrades without any downtime which is pretty cool. Networking Storage A common malpractice is keeping storage local to the host, this is a no no for most places. Keeping storage network based allows you to restart VM's on other hosts if said host with all the VMs on it fails, keeping uptime high; shared storage is key to a virtual environment. Without shared storage you will lose HA/DRS/FT and many other key features, planning for a centralized NAS/SAN is a good idea. generally your host will be fine with a small SSD, USB drive, or 2 HDD's in raid 1, you will want to keep it with something decently fast and a good of space for host swapping if it occurs, host swapping is bad, ballooning is okay if kept under control. But I'll take a performance hit! This is true you are limited to network throughput, but there are counters to this. DO's  Put your storage area network on a Vlan, subnet, separate physical network than your client machines! Not only will this increase security but will also cut down on the total traffic on the network Use jumbo frames when possible! Teir your storage! If possible run stagnate data on a different server that would be cheaper IE archive data on a NFS share, keep commonly accessed no high performance Storage Processors Use port aggregation! Binding ports together for better throughput is a smart idea Invest in 10Gb/E! It is pretty cheap now, your storage will love you! Thick Provision SQL servers and DB servers, thin provisioning will cause a sizable performance hit! Use an appropriate RAID, a 20 Disk raid 0 array is fast but deadly Monitor your logs, just because "it's up" doesn't mean your thin provisioned servers aren't gobbling up GB's you don't have! Choose the appropriate storage protocol for the job, NFS and Iscsi will give different performance! Don't  Cheap out on your NAS! This hosts all your data spend the bucks and make sure it is working Confuse Snapshots as backups for everything! Some servers like DC's will have a hissy fit with other DC's Skimp on Network adapters! Remember Network is the only way these things will talk to the ESXi hosts and VM's Not use consumer grade switches Do the opposite of Do's Some players in storage solutions are Netapp, emc, Equallogic/Dell, HP. for more on networking and serious discussions look HERE Now lets dig more into networking Making things modular and redundant are key to this environment, to tie all this together you'll need a good solid network, as a refresh NFS - Network file share, one of the slower storage techniques but very cheap and easy to maintain, can be greatly improved by use of jumbo frames. TCP/IP based Speeds Vary on Network Speed, latency is a bit higher than others iScsi - Block level access to data over the network, better performance than NFS by a long shot, gets a bump from jumbo frames but isn't as noticeable as NFS gains, TCP/IP based, Speeds from 10Mb/s-10Gb/s, latency is comparable to that of a normal disk if set up on a vlan, network, or subetnet made for storage. Cheap and easy to maintain, good if you have an existing ethernet network FCoE - uses the Fibre Channel WWN protocols over Ethernet instead of... Fiber! much faster than Iscsi since it does not have a TCP/IP overhead, speeds range from 4-10Gb/s latency is much lower, costs a bit more. Fibre Channel(FC) - FCoE but runs over Fibre The more net interfaces you have the better, generally you'll need 6 for a HA/vMotion environment, 1 Management 1backup mgmt, 1 Vm traffic, one for vMotion, 2 for Storage, You can piggy back VM network traffic to the vm management nic, and not see any real network hit, best would be to have one NIC for VM traffic and one for failover. Gig should be standard practice, for your storage and vmotion interfaces 10GB should heavily considered. for more about vlans, subnets and general networking click here Resource an allocation! Resource Pools! Resource pools help you divvy up resources in an environment where resources are scarce, combined with reservations help make sure resources are always available for vm's running in the pool. Provisioning! Just because you can over provision doesn't mean you should giving a host more ram than it needs and having it idle at 25% and expand to no more than 50% is wasting resources, running machines at 50-80% ram usage at all time is fine, unused ram is wasted ram. You also should take out anything not needed, virtual floppy drives, extra CPU cores, CD drives, USB support, ect... This will reduce the amount of overhead the VM needs in order to run, it will use up ram and for CPUs the scheduler does not need to check as often for cores idle and can get to VM's needing higher accesses(not really noticable except in stressed environments). I'll add more as wanted and address points or clarify things as needed just give me a heads up on what you want me to address.

Hmm I will check on that I am sure it can use more, maybe I was using 4 Yeah but, >10 cable runs + extra switches to make up for port loss + >10 nics costs would probably be the same if not more overall than a dual/single 10Gb/E cable run and switch to a few boxes Yeah but most server equipment has iscsi support be hardware or software, and for an ESX data store it is safe to say iscsi is generally supported. Thanks for the constructive critisim I will go back over some things after work or on lunch VVVV- Ah okay I guess I was using 4 then, 32 is a good number 8 is just wow really low, 32 is just right.

markus876 posted:I'm not sure that you should be generalizing these two options like this. Going off this http://www.vmware.com/files/pdf/storage_protocol_perf.pdf (they only used GIG and some of the charts all cap at 125MB/s) Talking Vanilla iscsi vs NFS (no jumbo frames, ToE, ect) iscsi will give you a better performance, it isn't much(Thought it was better than that to be honest) but it is there, and latency is generally lower. Since both are really easy to install configure I would still say iscsi would be a better option over NFS due to lower latency, and higher throughput. Of course it totally depends on the budget and resources you have to work with as well. I see what you are say about NFS vs. iscsi, NFS is very simplistic I just work with iscsi much more than NFS now so iscsi seems rather easy to manage. FreeBSD and OpenFiler are the two main NAS OS's I use I can say Freenas 7 offered great iscsi performance but always had troubles with NFS, might have been something I was doing. Openfiler seems neck and neck, but I notice lower latency with iscsi which is one reason I generally tend to use it over NFS. But yeah I'll give the part in the OP a rework tonight. Karthe posted:We recently got into virtualization, but unfortunately neither I nor my cohort had any prior experience with it, aside from whatever personal dabbling we'd done in the past. As such, I feel like our VM environment is almost too simple - we've not dabbled in resource pools, I had no idea about not thin-provisioning SQL environments, we only have 10/100 switches and no NAS/SAN...Things have been Running Alright(tm), but there are just so many red flags in our setup that I hope to god we never have to deal with a serious virtual host catastrophe.  this thread is good to ask questions in, no one here knows it all so ask anything regardless you trivial it may seem.

Are you running iscsi by chance? I see those hiccups sometimes with iscsi, software iscsi has to offload on CPU so seeing spikes is somewhat normal. As long as your VM's seem to me functioning fine I wouldn't lose too much sleep over it

It might not be your cup of tea but If you want to learn scripting/PowerCLI, you can script a datacenter rebuild whit shared storage adapters and what not. Once you set the script all you need to to is run it again to pick up where you left off. I might do a script like that and post it if anyone is interested, 3 hosts, 2 NAS, windows DC AD/NTP/DNS/gateway. Might save some people time who are learning but run into the 60 day limit

Anyone else getting crashes with installing vmware tools on Windows Server 8 beta? I totally lost the GUI and it locks up shortly after boot.

Bitch Stewie posted:So with just a pair of vSphere Standard hosts running 4.1 SP2, if/when we want to go to 5.0, is it worth upgrading or it just as simple to start over since other than the network and storage config there isn't that much to configure on each box? If you don't have the stuff on box and everything via shared storage, you might just want to wipe them and load 5 fresh. Ofcourse it depends if you have scripts inplace to reset everything and how many you have. We did 4.1 ESX migrate to 5 and it worked fine other than a flaky HW controller but that was HW not a issue with 5

stubblyhead posted:Has anyone gotten USB passthrough to work in VirtualBox? I've been struggling with it all weekend and just can't get it to connect, and it sounds like it's a pretty common problem. Can VMware Player do this with less hassle? Works fine for me, VMware player does it with ease and will sometimes automatically connect the USB even if you don't want it to.

Erwin posted:This is a dumb question but I don't think the VMware Update Manager documentation explains how to upgrade the VM hardware from 7 to 8 on your Update Manager VM. I feel like if I try to remediate it, it'll just explode halfway through power down the VM=>rightclick=>upgrade virtual hardware, I believe the binarys for the virtual hardware are kept on the ESXi host not vCenter or VUM. Not sure the way via VUM Orchastrator might do it but I am not sure http://pubs.vmware.com/vsphere-50/index.jsp?topic=/com.vmware.vsphere.upgrade.doc_50/GUID-A45CBEE5-C4D2-484E-A699-A5A577244DE0.html Dilbert As FUCK fucked around with this message at 21:34 on Mar 27, 2012 |

adorai posted:only partially related to virtualization, but can anyone recommend an FM1 motherboard that supports IOMMU? I want to build a new combo VMware / NAS box, passing my disk controller into the NAS VM via IOMMU. Don't know of any F1's but this AM3 http://www.newegg.com/Product/Product.aspx?Item=N82E16813131767 supports IOMMU. It's the board I use, it also supports 32GB ram which is an awesome +

This x100 this I started out doing VMware, now my shop runs hyper-v, I hate hyper-v so much it is so much lackluster than ESXi, but head and shoulders over citrix(atleast for what I do) in terms of stability/performance

My templates are Core/Ram 1:2 per windows instance 1:1 per linux instance but usually it turns into custom ratios depending on what the VM is doing

FISHMANPET posted:So as I read through Masterping vSphere 5 and VMware vSphere Design, I'm mentally planning my departments virtualization build out (and my boss is listening to me on this, so I can't gently caress it up) and I decided to look for 10 Gb Switches. How much data are you moving again? Not saying that 24Port 10Gb isn't awesome but how many can you get at that price? It might be more feasable to order some <12 port 10Gib as a backbone for Iscsi/NFS and vMotion, and run everything else on Gig or aggregated gig.

FISHMANPET posted:University pricing, so pretty much as many as I want. And right now we're probably a year out from anything (that's when the richest department's infrastructure goes out of contract) though when I actually think about it that's not a lot of time. Well depending on your environment and what throughput you need you may want to look at Fibre Channel, it may provide better performance for things that need high I/O and low latency like DB servers, front end web servers(that get constantly hit), and the like. It is a bit of a hit 8Gb/s but you latency is non exsistant if done right. 10Gb would be great for things like Vmotion, FT, or backup lines to the Data stores; and use Gig => 10Gig for web/other traffic. 10Gb is a great investment, and will give you a lot of growing room that you might want, but you might waste money on buying what you may not ever utilize fully. If you set VM affinities right such as things like Spam filter servers for email on the Machine running the Email server you will cut a lot of traffic out, same with other servers that have to access each other, like servers that access a DB server or what not. just my 2c but, Depending on your environment I would do like this High I/O servers/DB servers => Fiber Channel High usage Mission Critical servers => 10Gb/E Other servers and web(access) => 1Gb/E Run Affinities to keep servers that have relations to run on the same host Cause to utilize those 10Gb switches ya going to need 10Gb network cards E: You might also want to look into SSD caching for some of the servers it can really prove useful Dilbert As FUCK fucked around with this message at 05:07 on Apr 6, 2012 |

FISHMANPET posted:We'll most likely be getting a Compellent SAN with an SSD tier, so that's taken care of (I assume that's what you mean by SSD caching?). more here http://www.unifiedcomputingblog.com/?p=108 As far as your net admin goes re assure him that you can have a stand-by/failover nic for port aggregation Of course I don't know how many servers you have or want to consolidate so only take what I say as something to consider.

FISHMANPET posted:So I'm reading through Scott Lowe's "Mastering VMware vSphere 5" and I have to ask, does it get any better? I just started the networking chapter, but after 4 chapters of "Launch the vSphere Client if it is not already running, and connect to a vCenter Server instance." I'm getting pretty exhausted of being taught how to bush buttans. You can always do everything via powerCLI to make it a bit more challenging, but if you did the 4 then 5 will seem dry
