Kernel panic when trying to start a OEL5u5 template vm

Question

Hi,
I am in the process of following a guide to setup various oracle vm templates, so far I have installed OVS 2. 2 and got the OVM Manager working, imported the template for OEL5U5 and created a vm from it.. the problem comes when starting that vm.
The log in the OVMM console shows the following;
Update VM Status - Running
Configure CPU Cap
Set CPU Cap: failed:<Exception: failed:<Exception: ['xm', 'sched-credit', '-d', '32_EM11g_OVM', '-c', '0'] => Error: Domain '32_EM11g_OVM' does not exist.
>
StackTrace:
File "/opt/ovs-agent-2.3/OVSXXenVMConfig.py", line 2531, in xen_set_cpu_cap
run_cmd(args=['xm',
File "/opt/ovs-agent-2.3/OVSCommons.py", line 92, in run_cmd
raise Exception('%s => %s' % (args, err))
>
The xend.log shows;

as always any help is much appreciated.

I have set_on_crash="preserve" in the vm.cfg and have then run xm create -c to get the console screen while booting and this is the log of what happens..

clear as mud to me.
are there any other logs that will help me?
I have now deployed another vm from the same template and used the default vm settings rather than adding more memory etc - I get exactly the same error.
