Kernel panic when trying to start a OEL5u5 template vm

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.

File "/opt/ovs-agent-2.3/", line 2531, in xen_set_cpu_cap
File "/opt/ovs-agent-2.3/", line 92, in run_cmd
raise Exception('%s => %s' % (args, err))

The xend.log shows;

[2012-11-12 16:42:01 7581] DEBUG (DevController:139) Waiting for devices vtpm.
[2012-11-12 16:42:01 7581] INFO (XendDomain:1180) Domain 32_EM11g_OVM (3) unpaused.

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.

    Which version of OVS are you using ? 3.1.1 ? Which template are you struggling with ?

    I have had word from Oracle on this and apparently it is a known issue with my server (Dell 815), our processors (Opterons), our OVS version (2.2) and the kernel verion of OEL 5u5 not working in combination together. change any of the variables and it works... which is brilliant except we have to use this server with this version of OVS for the particular 5u5 templates we are installing :D

    We are going to try a work around with live CD and upgrade the kernel once the templates are installed.
