Try adding:

device_model_version = "qemu-xen"
device_model_override = "/usr/bin/qemu-system-x86_64"
bios = “seabios"

to your VM conf. This gets my VMs to start booting, at which point they triple fault repeatedly - but the triple faulting doesn’t show device model errors for me.

The commit I reference in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=737905 works if you build packages manually though.
