I haven't followed the thread; I just saw it here on xen-devel that:

"You might want to communicate to xen-devel that you rely on
[vifname support]"

Currently we use xm and xend, specify vifname in the PV guest's
config in order to get a dom0 network interface of a given name.
That functionality is required for us.

If I misunderstood then I apologise; it seemed that it was being
indicated that this functionality didn't exist with xm and there
were no plans to provide it.

Cheers,
Andy
