[vfio-users] Help Patching Qemu for Vendor

[thibaut noah]

Install qemu-git from the aur and you would have the patches with ti.

You're talking about degraded performances, could you be more specific?
I personnaly have hyper-v features and i don't see any difference
whatsoever.
Did you remember to modify your kernel config?
