attached you find the xm dmesg output of my xen-unstable machine, first domU starts correct, second/third crashes (see log).

dom0 and domU were both compiled with smp support (smt
enabled) on a
dual xeon 2.8.

did i missed something at kernel configuration?


No. I reported this problem some time back and am still seeing it
daily: http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=267

Sounds like a critical bug. Is anybody taking a look at this? BTW, is this specific to PAE?

It's on our 'most critical' list, but help is always appreciated. You
need a machine with >= 4GB to repro it. xm-test can throw it up, but
having a simpler repro recipe would be a big help
There's a 'vcpu crashed' x86_64 issue too, though I forget the bug
number.
I have not seen it since last Friday. The defects is http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=358
