[libvirt] [PATCH 0/3] reattach pci devices when qemuPrepareHostdevPCIDevices() failed

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.
