Hi Ivo-
Can you mention how you built it?  I checked out xen-unstable, tried
modifying the Config.mk to change the QEMU_UPSTREAM_URL variable,
however when I built with this new url it complained when it tried to
checkout the qemu traditional because the revision doesn't exist at
that url.  So instead I built normally, then went into
tools/qemu-xen-dir and added the git remote for qemu unstable, checked
out the master branch, ran ./configure, then backed up to the main
xen-unstable.hg folder and did sudo make dist and sudo make install.
When I then started the VM with the config containing device model
qemu-xen nothing changed.  I then added the line:

device_model_override="/home/derickso/xen-unstable.hg/tools/qemu-xen-dir/i386-softmmu/qemu-system-i386"

And started the VM, but got a bunch of errors:

derickso@xen:~/xen-unstable.hg/tools/qemu-xen-dir/i386-softmmu$ sudo
xl -v create /etc/xen/ubuntu.conf -V

Any suggestions?
