Are you using the qemu-dm that's in the xen-unstable tree? 

I can't get the SMP kernel to boot. I got a 2.6.16 SMP kernel, made sure
the options were set in the config, and I get the following error
repeatedly:

"Unknown interrupt or fault at EIP 00000060 c0100295 0000294"

Either way, if you'd like to do more testing using xm-test - then it
will need to be patched to have the correct config options.

Thanks,

Dan
