I fixed error in hvm profile and got a similar qemu-dm.strace ( /usr/lib64/.../qemu-dm).

Hm, I'm getting:
[2009-02-23 15:26:18 4380] WARNING (image:482) domain win7: device model
failure: pid 5409: died due to signal 7; see /var/log/xen/qemu-dm-win7.log
Hm, signal 7 - SIGBUS. I wonder if
Using stub domains doesn't work either.

I see:
