Hello, oVirt 3.2.1 on F18 One mgmt server + one host. At some point the host had some problem and was rebooted at reboot ther was a problem because I got detected unhandled Python exception in '/usr/share/vdsm/vdsm' watching at http://www.ovirt.org/Troubleshooting I verified that for some reason vdsmd.log was root.root. So I set correct permissions and restarted the node. Now it stays at "unassigned" status from an engine point of view, that I don't know what means... In node messages Jul 14 16:55:02 management02 vdsm vds WARNING Unable to load the json rpc server module. Please make sure it is installed.
