Couple of libvirtd warnings

[jeremy avnet <brainsik+libvirt@xxxxxxxxxxxxx>]

Hello, I recently upgraded to libvirt 0.8.3 and qemu 0.12.5 and I'm seeing these messages in syslog:

libvirtd: 09:52:34.591: warning : virStorageBackendQEMUImgBackingFormat:623 : Unexpected exit status '1', qemu probably failed

libvirtd: 09:52:34.746: warning : qemudParsePCIDeviceStrs:1422 : Unexpected exit status '1', qemu probably failed

I'm not having any problems, but I'd like to know what these mean.

Thanks!
