Description of problem:

There is a problem with vds_installer: after host installation (RHEL6.3), I can't run vm with spice console attached. 
libvirt fails with the following error:

 Thread-792::ERROR::2012-05-09 12:07:17,633::vm::602::vm.Vm::(_startUnderlyingVm) vmId=`28fdeb28-23c3-43d0-b344-446c150d87e5`::The vm start process failed
