my vfio gpu passthrough setup on a 5900x.
I don't recommend using it as is. read the win10.sh script for reference
this setup has been tested with latency sensitive audio stuff with no issue. I livestream from the vm no problem
assumes you have a win10.img disk image and
virtio-win-0.1.185.iso which you can get from https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso .
the script also assumes that your sudo doesn't ask for password
you also need to have vfio-isolate installed. I also have vendor-reset to fix the reset bug on my rx570.
libcgroup is also needed for cpu isolation (which is enabled by default in the script)
you also need to set up a br0 bridge device, example with nmcli using interface enp42s0
nmcli con add type bridge con-name br0 ifname br0 autoconnect yes
nmcli con add type bridge-slave ifname enp42s0 master br0
# use nmcli to set static ip on br0 if needed, as if it was your main connection
nmcli con down "Wired connection 1"
nmcli con up br0
nmcli connection add type tun ifname tap0 con-name mytap mode tap owner `id -u`
nmcli connection mod mytap connection.slave-type bridge connection.master br0
I use barrier to share mouse between linux and windows
to start the vm, you need to cd to the path where the script and the disk image are located and
start ./win10.sh
