[Users] Unanble to start spice console.

After defining a new VM, hit 'Run Once' and chose to install F18 by attaching an iso. The green arrow comes up next to the new defined VM. When I select to start the console, Error dialog pops up with message - "Error while executing action: A Request to the Server failed with the following Status Code: 500" Engine log has following to report - 013-05-03 14:08:32,363 INFO [org.ovirt.engine.core.bll.SetVmTicketCommand] (http--0.0.0.0-8080-3) [385b5ed5] Running command: SetVmTicketCommand internal: false.
