DevNull posted:I work on the monitor team at VMware and we run several machines dedicated to nested testing. Mostly ESX in ESX, but we have a few WS in ESX as well. It is slower, but we expect the same correctness. You, I understand. You are supposed to test all kinds of wacky configurations your customers may have. It's the customers that I don't get  . But anyway, is VM in VM @ VMWare now supported? I tried it back in the early 2000s (2003 maybe?) when VMs were the new cool thing and VMWare workstation caught me trying to install it in an VMWare VM and basically refused to let me do it. Again, not that I would have had a need for it, but experimenting is fun.

Boris Galerkin posted:How do I do that? Wikipedia says Hyper-V is a Windows thing and I absolutely need a Linux host. You don't, Hyper-v is a windows thing. What could help you quite a bit would be if you would have a virtualization server that will have a windows guest. Now, that server can be linux with qemu+kvm or can be windows with Hyper-v, doesn't matter, the performance will most likely be better than running the machine locally. Given the nature of your work, running the primary development machine in a VM would not even be a consideration.

Potato Salad posted:They can barely support their rdbms. Their erp is an eternally burning heap of fire so outpaced by modern commodity platforms that it's unthinkable that any entity that wasn't married to Oracle by 1998 would have a relationship with them today. From personal experience, while I was doing some performance analysis on a big java application that was using Oracle backend, Oracle linux had the following advantages over RedHat (7.2 era):
And, oh, they were trying to sell me at the time (once per month) their live-kernel patching mechanism. Which is not even theirs. But hey, they sell it and probably support it.

Boris Galerkin posted:I got Windows 10 running on a Linux (Fedora) host using the virt-manager GUI to set it all up. Storage is via virtio and I'm using a spice server for the graphics (I hope those are the right way of saying it). In my personal opinion, the easiest way to go about is with samba. But, instead of setting up samba server on linux, tell windows to be the server. On windows you can do that easily with network share a folder and on linux you can access it by mounting it using the cifs filesystem. Example mount command: code:About the UI: on my system (using KDE) that "bar" is the title bar of the window. Look your DEs configuration if you can make that go away. The menu is not possible to make it go away, only the toolbar (under the View menu). They would go away though if you go full screen, but really they don't take that much space.

Boris Galerkin posted:I’m using gnome but I’ll look into it. I don’t wanna go full screen though, because the only reason I’m doing this is to be able to have Office 2016 look and feel like a “native app”. This current setup is working great because I can snap the entire VM window to the sides and make the window smaller/bigger etc. Inside the actual guest I have eg Excel maximized so I’m just treating the entire VM window like it wee just the Excel app. When I get some more time I’d like to see if I can add “multiple” displays to this so that I can trick Windows into thinking I have a second display that I can throw PowerPoint into. The simplest window that I was able to get was from running qemu by itself: code:

Boris Galerkin posted:Does that command mimic what happens when I start virt-manager and press "run"? Like I already have the VM created, can I just start up the VM with a script like that? Yes, that's what virt manager does too ( well, maybe a bit more complicated) but qemu is what actually runs your VM.

evol262 posted:virt-manager is essentially a frontend to libvirt (like virsh). Sure, a lot more complicated  . But if all he wants is that border-free VM, nothing more, then a few arguments on a shell script is not that crazy.

You have two options here: - Configure the guest network in bridge mode (so it will run on the same network as the host): https://wiki.libvirt.org/page/Networking#Bridged_networking_.28aka_.22shared_physical_device.22.29 - Configure port-forwarding for the NAT: https://aboullaite.me/kvm-qemo-forward-ports-with-iptables/ https://wiki.libvirt.org/page/Networking#NAT_forwarding_.28aka_.22virtual_networks.22.29 The windows samba ports are quote:The following ports are associated with file sharing and server message block (SMB) communications: And, I think (not 100% n this one) that you need a password for the user, though it may be possible to convince windows to let you share without one, but is not straightforward. Also, don't forget, an admin user can use the default windows shares of the entire C drive, called: C$ (the name of the share). So, with an admin account you can mount //WINDOWSVM/C$ Oh, and another thing about the qemu parameters that libvirt passes: look at them and you don't need to set quite a few of them. Actually, most of them, for your purposes are useless. Don't need USB, don't need to set the accel=kvm, don't need -S and -object tls crap, monitoring, all kinds of devices. Removing that can shorten the list quite a bit. Or, just start the machine from virt manager like before and don't worry about it. Volguus fucked around with this message at 15:58 on Mar 2, 2018 |

anthonypants posted:Set a password. Can you access it if is NAT-ed without port forwarding? Edit: Now that I think about it, from the host you should be able to. So, forget about port forwarding if you don't need access from anywhere else Volguus fucked around with this message at 20:33 on Mar 2, 2018 |

Goonerousity posted:This is exactly what I needed, thank you. I’ll stick to windows 10 and full screen virtual machines when I need to write c I used to play wow on linux (most recently last month with the new expansion, now i stopped again) and it's perfectly fine with wine. By perfectly fine I mean 30FPS in Orgrimmar on Mal'Ganis. FreeBSD performance shouldn't be any different from the linux one. Now I'm playing Diablo, and it works as it should. Nothing to complain about here. What im trying to say is that you may not need the passthrough (even though it does provide the best FPS) for normal gameplay. If you're one of those streaming on twitch ... then stick with windows, yes.

Mr. Crow posted:Regardless of the systemd discussion because, agreed, no one's mind is gonna be changed; I'm not sure I've ever heard a single person defend pulse audio. It's a dumpster fire that while kind of works now, needs to be replaced; if only because of the negative stigma it has. I've only heard good things about pipewire. While I've heard only positive things about pipewire too, I'm a bit more reserved about it now, since I am using Fedora 34 that comes with it by default. I have an application (written in Qt) that I use to change the default audio output device. It's more than 5 years old and it works just fine with pulseaudio. Since upgrading to F34, even though pipewire has a pulseaudio compatible API (wrapper or whatever it is), it behaves a bit differently. For example, when the DE starts (KDE), it tells me that it connected to the server, but that there are no audio outputs available. If I quit the app then restart it it works just fine. Now, maybe the pulseaudio layer is not that stable yet, so I've been meaning to write it against pipewire directly. The documentation, however, of that API is ... not quite existent to be honest. I haven't spent that much time on it, but meh I kinda gave up for now. At the moment I just live with it not starting when the DE starts and I start it manually after. I hope they'll stabilize it soon.
