qemu: check actual netdev type rather than config netdev type during init
Hi Laine, I met a problem during testing this bug, destroying the guest which attached a VF interface will report an error: # virsh attach-device rhel65 hostdev.xml Device attached successfully # virsh destroy rhel65 error: Failed to destroy domain rhel65 error: operation failed: failed to kill qemu process with SIGTERM # ps -ef | grep qemu root 11258 4695 0 05:10 pts/2 00:00:00 grep qemu some logs are: 2014-05-20 09:09:55.064+0000: 9794: warning : qemuProcessKill:4254 : Timed out waiting after SIGTERM to process 9908, sending SIGKILL 2014-05-20 09:10:00.067+0000: 9794: warning : qemuProcessKill:4286 : Timed out waiting after SIGKILL to process 9908 2014-05-20 09:10:00.067+0000: 9794: debug : virObjectRef:168 : OBJECT_REF: obj=0x7f7444122840 2014-05-20 09:10:00.067+0000: 9794: debug : virObjectUnref:135 : OBJECT_UNREF: obj=0x7f7444122840 2014-05-20 09:10:00.067+0000: 9794: error : qemuDomainDestroyFlags:2111 : operation failed: failed to kill qemu process with SIGTERM Further information: I try to attach a normal PCI device to guest, and no error happened. Although I think this problem is not related to this bug fix, I just need your confirmation. If so, I will report a new one to track it.

This SIGTERM problem is not related to this fix, I tested on another 82599 machine, and no happened.
In latest libvirt, there is no error like "Unable to determine device index for network device"

attach-interface works well, so I choose to change the status to VERIFIED.
