At work I have a pretty beefy workstation for my development work. We run multiple VMs locally for testing and whatnot, however I have a Windows VM that I use for various windowsy items (Outlook etc.).

However, we recently took down some old servers and I got a pretty hefty RAM upgrade (192GB). What I was thinking of doing was having my Win10 VM put into my RAMdrive with daily backups. The general plan:

FSTAB: Create a ramdrive out of 100GB of memory (the max size of the VM)
FSTAB: Mount ramdrive
FSTAB: Move VM files to RAMdisk

kron or something else:
Back up files nightly at xx time. May have to shut down the VM and back up, not an issue.
check every x time frame to see if the VM is running, if not compare the filetiems and back up if the ramdrive is newer. (Probably some other much easier way to do it).

before shutting down primary machine:
Make sure VM is shut down, and backed up.

Is this feasible or just something that is too difficult to get working right to even really do?

Base Specs of my workstation:
HP Z820
2x Xeon - 6 core processors
500GB SATA SDD
2TB HDD

Fedora 28


I've been looking at a lot of things and think it might be doable, the biggest hurdle would be saving changes. In all fairness, nothing is saved locally on the VM that is actually important, so losing a day on it would be fine.

If you had 192gb of ram, wouldn't you?

What did you say? Free RAM? gently caress yes, I will fill my poo poo up (I actually was 3rd in line so instead of 16x16, I have 8 16's and 8 8's. Not complaining!).

For other reasons, it's to speed my VM up as much as possible because I want to see what kind of poo poo I can do.

Just use ZFS and set the volume to async. You don't need to dedicate the ram but will get much of the benefit.
