The situation
videocard n�1 Nvidia Ge-force(used on host linux)
videocard n�2 Ati radeon(used on guest windows 7)
host is Slackware 14.2,kernel 4.18.15
I had set vfio to pass a ati card to windows7 guest
Configure /etc/modprobe.d/vfio.conf
options vfio-pci ids=1002:68f9,1002:aa68
configure /etc/modprobe.d/blacklist.conf
blacklist radeon
configured /etc/default/grub
And of course make the initrd and reboot
I use virt manager and passed the pci devices
This is the xml of libvirt for windows7 guest

The guest start,but return error code 12 "no more resources avaliable"
I suspect is a problem with hdmi..my cards(the audio card and the ati card)
use the same driver(snd-intel-hda) and I cannot blacklist it(no sound at all)
Any solution?

Can I pass the card gpu but no hdmi?

Hdmi must go with the video..probably is this the problem?
