Bug Report - Debian, HVM, + qemu-xen-traditional "-domain-name: invalid option"

Bug Report - Debian, HVM, + qemu-xen-traditional "-domain-name: invalid option"

[merc1984]

Debian Testing in dom0 & domU, with xen 4.3.0-3 installed as packages
from the repo.

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                 

In /var/log/xen/qemu-dm-cygnus.log it only says:
 -domain-name: invalid option.  

Note that I haven't enabled VGA passthrough at this point, on either
dom0 or domU.  The failure strictly has to do with device_model_version
=qemu-xen-traditional .  Set it back to qemu-xen and domU starts great. 
But I need -traditional for VGA passthru.

In a search of /etc the only occurrance of 'domain-name' is in
/etc/xen/scripts/network-nat, but commenting out that line doesn't
change anything.

I notice that two bugs for this have been filed on libvirt-bin, but I
didn't even have it installed.  And installing it didn't change
anything.

My .cfg file works great with device_model_version = "qemu-xen" and no
other changes except enabling bios = "seabios".  I've tried commenting
out everything except the bare minimum, but nothing changes.

Oh?  I didn't find that anywhere on The Internets.

But I read that qemu-xen does not support VGA passthru yet.

How is it possible to get VGA passthru?  Are there any instructions
anywhere?

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.
