Hello,

My idea was to passthrough GPU to specific VM. According to many informations from the Internet, I'm doing this like that:

1. /opt/xensource/libexec/xen-cmdline --set-dom0 "xen-pciback.hide=(03:00.0)(03:00.1)"
   but still even after reboot I see it on lspci
2. xe vm-param-set other-config:pci=0/0000:03:00.0, 0/0000:03:00.1 uuid=c41704d0-a1f2-6bc1-fe2e-adc26697e636
   for old Nvidia 8600 and GT430 it doesn't work - Windows VM see that device, drivers are installed but all the time I have error 43 and this device is stopped
   for Radeon 7870 it work ok

Audio and USB is working with that metod also.

Is this connected with Vbios of this GPU's ?
