Description of problem:
After putting RHEL 6.4 host to maintenance, updating it to RHEL 6.5 via yum update, it is not possible to activate the host. Host is in unassigned state.

it seems that problem might be caused by updating libvirt package during the process

 libvirt                                           x86_64    0.10.2-29.el6                          rhel65-brq                      2.3 M
