Sorry, meant xend-debug.log, but it doesn't matter, as there is plenty
of good info in the xm dmesg for this particular problem.
Judging by the messages, I would say that the guest is completely and
utterly crashing itself.
The first failuer is that the guest is either executing garbage, or
using an instruction that is not supported by Xen. I'm not 100% sure if
anyone has been able to boot Solaris 10 on HVM. This may be something
that needs fixing in the hypervisor.
It may be worth trying the Xen unstable version, to see if it's fixed
the problem (there's been quite a few fixes for various decoding bugs
and such).
Once it's failed to decode the instruction, it will probably not
recover, and in your case, the guest crashes out with a "shutdown",
which is essentially the consequence of a triple-fault - non-recoverable
multiple faults, basicly.
What makes me wonder a bit is the fact that the second domain
(auto-restarted) fails in a different manner, as does the third attempt
to restart the domain - I'm not sure if this is just because of some
timing of the failure condition (depending on the exact
circumstances/timing of the startup) the guest may fail in different
places because it triggers a different part of the code at different
times.
