Not a lot, I've attached good/bad dmesg & xend.logs, but I can't see
much indicative in them, other than some errors about L1 entries in the
good dmesg log which I believe are related to the bug with I patched
(I'll report in other thread).

Yes the hardware is quite a lot different. I've had a good look at the
cpuid flag, found the cpuid utility & wikipedia page, but I can't find
much documentation on the xen cpuid parameter other than some fairly
arcane entries in xmexample.hvm. The cpuid utility produces output in
hex, while the cpuid flag wants input in binary (with extra controls).
Is there any formal documentation that describes cpuid, or an easy way
to generate cpuid parameter values?

Also my DomU is PV rather than HVM and I see that cpuid is only in HVM
xmexample files. Is this just a coincidence or is cpuid a HVM only feature?

thanks,

Anthony.
