Yeah nvidia + vfio works, you can see my archlinux guide if you're interested
7) The fact that XEN doesnt support resetting pcie devices after a shutdown/reset, which means that for most radeon cards you have to restart the host after the first run or use some hacks (ejecting the card, etc)
Works on kvm
Yeah there's a few patches still needed, specially on intel, i see you're using an nvidia card on your host, so if you're using the nvidia drivers you'll probably need to patch it too, and also you'll need the lastest qemu-git (or qemu 1.7 when it gets released) that support the new pcie reset interface on kernel 3.12, as for seabios the lastest release doesnt require any additional patches, also most of my posts here are outdated you should probably check out my...
Qemu-kvm with nvidia cards works using vfio-pci, there has been success reports of people using geforce 660gtx
You might need to patch qemu and kernel to get it working, see:, as of kernel 3.12 the patches wont be required anymore see:
It might need only one installation, but i think you'll need an account for each vm, since each machine will be its own pc
Yeah, using linux cgroups (if you're using kvm) you can assign a share or percentage of the cpu resources to an application, or you can just give more priority to the VM thread
Yes i believe its possible, right now i "reserve" 2 cores, 4gb of ram to the host and a cheap radeon 5450, and my windows 8 guest runs on 6 cores, 8gb of ram and a radeon 6950, if i had another GPU i could easly create 2 windows gaming VM's, once i get some money i plan to get another GPU and more ram to do this.
Right now using the IGP as the primary device doesnt seem to work using vfio from the reports i've seen, you should disable it. Once you build the kernel you'll see 2 files, the kernel and the headers to install both do this: Code: sudo pacman -U linux-mainline-* Then you'll need to upgrade grub: Code: sudo grub-mkconfig -o /boot/grub/grub.cfg Attached here is the kernel package, updated to 3.9.6 with this patch applied:...
