No, never tried that. Have since moved the box to plain 64-bit Debian
Lenny using KVM to run (currently) 6 HVMs, with 4 more in various stages
of testing (all using kvmbr0 bridge device on top of a bond0 made up of 4
gigabit NICs).

Yeah, the Ubuntu launchpad and forums for hardy are full of libc6 issues
regarding bus errors and truncated libraries, with no real solution as
yet (that I saw).

What's annoying is I was able to do the same using the supplied networking
scripts in Xen 3.0.3 in Debian Etch. Something changed between that and
Xen 3.2, but I was never able to figure it out. Tried a couple of times
to figure out all the ip, brctl, and ifconfig commands that were going on
in the background, but gave up in frustration (oh, if only a distro had
the balls to unify networking commands like the BSDs do, such that
ifconfig is the only command you need to do all this).

Good luck. Hope you get this one figured out.
