Hi All,
it is possible to use pci/gpu passthrough with xen and libvirt?
If yes, how is the syntax? Can I get an example?
Yes, host PCI devices can be passed to xen guests using libvirt. Below
is example config of a "managed" PCI host device. For more details see
https://libvirt.org/formatdomain.html#elementsHostDevSubsys
