Hi Ralf,
I'm having some trouble reproducing this problem.
Could you be a bit more specific about which versions
of xen-unstable and qemu-xen-unstable (aka tools/ioemu-remote)
you are using:
cd $XEN_SOURCE_DIR
$ hg tip
$ (cd tools/ioemu-remote && git log -1;)
Also, which dom0 kernel are you running?
