Thanks Sergey,

I switched the BIOS from APIC to PIC, and added 'nolapic nosmp' to the kernel
line and now it boots OK. However I would like to use smp support to get my dual
core's working.

I will try again a custom kernel dom0 build.
I notice when doing a custom build, xen patches the kernel to
offer a "Subarchitecture Type" set to default 'Xen Compatible'. I can imagine you
would use this setting for domU kernel, but for dom0 should it not be set
to PC Compatible and family set to Opteron?

Eg:

Subarchitecture Type (PC-compatible)
Processor family (Opteron/Athlon64/Hammer/K8)  --->

Thanks
John
