When setting device_model_version =qemu-xen-traditional in prep for VGA

passthru (as qemu-xen does not yet support it apparently), on xl create

it consistently gives:

Parsing config from cygnus.cfg

libxl: error: libxl_dm.c:1300:libxl__destroy_device_model: could not

find device-model's pid for dom 4

libxl: error: libxl.c:1408:libxl__destroy_domid:

libxl__destroy_device_model failed for 4

debian has removed qemu-traditional long time ago

Looks like I'm snookered. From Fabio's comment I inferred that maybe Debian's 4.3 packages have only qemu-xen, which does not support VGA passthru.

So maybe current unstable does. I git cloned that and tried to compile, but it fails. So I downloaded the current 4.4 SUpported, but its compile fails as well.
