Proxmox for my gaming computer?

[ioconnor]

I'm new and asking questions, possibly stupid ones, so I don't go down a wrong path here. With that in mind...

Proxmox is advertised as taking 1-3% overhead. I'm thinking promox might work nicely on my gaming computer. So I could power up windows 7 and run games without noticing promox was in the stack. Graphical games that need the GPU and the large local screen.

Ideally I'd be able to hit some key combination and go back to proxmox and power up a linux distro and do real work. Possibly sharing mutual disk space with the windows 7 machine.

Finally if that works would it be wrong to assume I could also do it with say a system 76 bonobo laptop?

Thanks for the help.

For now KVM main use on the server side,"1-3% overhead" is for CPU/Disk/Ethernet performance.
Future maybe we can expect project like http://virgil3d.github.io/

It's my view and maybe wrong...

No unfortunately that will not work. No virtualization solution has yet mastered having proper acceleration on the guest VMs, with Virtualbox coming close (but not close enough for gaming).

Although I am not sure it will work, if you absolutely need both virtualization and gaming, maybe you can try installing the (expensive) Windows Hyper-V Server as a host, play games on it and install guest machines as you see fit.

The openVZ/KVM overhead on Proxmox is indeed small enough for servers, but 3D graphics will simply not work.

*edit* Just looking at my answer I realized that you can also have Win7 as host, put Virtualbox on it, play games on it and run guests inside Virtualbox.

you can use pci passthrough to pretty much give the physical graphics card to any KVM VM and Ive seen people claiming that this works quite well. keep in mind that this is not first hand experience tho

Thank you all for your comments. In the meantime I gave Proxmox a spin. I like Proxmox and it works fantastically as a server... Gaming on the other hand...

Once again thanks for all the good comments.
