[Users] Unanble to start spice console.

[snmishra at linux.vnet.ibm.com]

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 -
