vdsm logs

Environment:
RHEVM 3.0 ic139 with RHEL6.2 host, vdsm-4.9-96.el6.x86_64

"vdsClient -s 0 getVdsCaps" fails with "unexpected exception" when there are two "redhat-release-server" packages installed, therefore the host moves to "Non-responsive" after the installation's reboot.

rpm -qa | grep redhat-release
redhat-release-server-6Server-6.2.0.2.el6.x86_64
redhat-release-server-6Server-6.1.0.2.el6.x86_64
