Public bug reported:
when doing suspend with pci device, nova tries to detach the pci device from
libvrit dom.
after calling guest.detach_device nova checks the dom to ensure the detaching
is finished.
if that detach failed (because of using old qemu in my case) the
_detach_pci_devices method failed with the following error instead of raising
PciDeviceDetachFailed
