Thanks for adding also these very useful tests, currently I use nearly 
always debian on pv domUs.
Briefly looking at your patches it seems that you use pygrub also for 
domUs installation, I use the installer kernel and initrd directly 
instead, for example:
kernel = "/boot/domu/wheezy/vmlinuz" (from .../images/netboot/xen/)
ramdisk = "/boot/domu/wheezy/initrd.gz" (from .../images/netboot/xen/)
extra = ...

Is there some "special" reason to install domUs starting with pygrub 
instead of directly?
Since last year with recents grub2 of Sid the domUs don't boot anymore 
with pygrub and I use pvgrub2 instead, I haven't tried installation from 
pygrub instead of directly but perharps it has the same problem.
Is pvgrub2 test now missing on osstest?

Thanks for any reply.
