That error is from libvirt, not qemu, so you are asking on the wrong list. But when asking on the libvirt list, be sure to mention what version of libvirtd is running on nova-compute-lnx001. Meanwhile, when libvirtd gets in a stuck lock state, you can often restart libvirtd to get past that point, with no negative consequences to your running qemu guests. --=20 Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org ------enig2GBDLBXCHGMLGPNPXSNDP Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (GNU/Linux) Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBCAAGBQJRQOfdAAoJEKeha0olJ0Nqb3oH/3H8l+tXStraavddE58jBdiO L4mY4j1rhLacRTriS+OE6YYNrvwmhUuVGMSGhbpnowG5OqLgmW6rSY8oTGm8HMTB R9KjyA0cfGt6Oc9dVB10h43ptmoA65j/ZWOatfLd2a+5pHWNkogT229occsm9Ifj 1hCTv88jipEgQnTXdM1aHFIM2t1PQUPa8ilXdZlXnfbH3Vnzv0TrJZbprkXlqhGq VbykPy3650+GKcYSnfu2hSlWPlDq8lm5mL0znVPKaOHzpNCshQEgn8h+FajeNuF0 NHgEruchE3LSOS6Mc+WuAs+jDYKHxDVDeNeBipIe+SF8rqyE95BE7oixasbRdD0= =rW5y -----END PGP SIGNATURE----- ------enig2GBDLBXCHGMLGPNPXSNDP--
