[libvirt] One question about ACS for pci passthrough
Hi all,
In libvirt, it doesn't allow non-ACS switch to assign devices to guests.
Is this required for X86 to support PCI passthrough?
On my power machine, ACS capability can't be found. I think HW doesn't
support it.
I don't know whether this is a special situation, and I have to set
relaxed_acs_check = 1.
Thanks.
