[Xen-users] migrating ballooned domains

I'd like to shrink a domain using the balloon driver, and migrate that
shrunk domain to a small host.   When I try this, xend on the destination host
fails with
 line 120, in free
     raise VmError('The privileged domain did not balloon!')

This error is due to the destination xend trying to create a domain
of the original size, rather than allocating just the shurnk size.
I can successfully migrate a domain created small enough to fit on the
destination host at the domain's original size.

Is this a fundamental issue, or just a bug in xend?   I'm still scarred
from the last time I hunted through the xend python so I have not actually
tried to run this down this myself.
