[libvirt] [PATCH v2 0/2] Block assignment of PCI devices below non-ACS capable switch

[Jiri Denemark]

This is a patchset for blocking assignment of PCI devices below non-ACS
capable switch. In case user still wants to assign such device even though it
might not be safe, she can specify 'relaxed_acs_check = 1' in qemu.conf

Special thanks to Chris L. who created a standalone program the PCI check.
This code is a port of that check to libvirt.

Changes in version 2:
- permissive attribute for <hostdev> was removed
- new 'relaxed_acs_check' config option in qemu.conf for relaxing the check

Jiri Denemark (2):
  Tests for ACS in PCIe switches
  Use pciDeviceIsAssignable in qemu driver
