When I try to attach a pci device to guest OS, libvirtd resets the pci failed.
But I can not use this pci device after attaching pci device failed. I must
rollback the operation by hand.

I think libvirtd should auto rollback the operation when it failed.

Wen Congyang (3):
  remove devices from driver->activePciHostdevs when
    qemuPrepareHostdevPCIDevices() failed
  reattach pci device when pciBindDeviceToStub() failed
  reattach pci devices when qemuPrepareHostdevPCIDevices() failed
