Is networking working in unstable?

hi,

I have been trying to get the latest unstable Xen running, and while I
am able to create domains (from a handrolled initrd) and log in on the
console, I can't seem to get them on the network, no matter if I
specifify ip & netmask in the config-file, or in 'ifconfig eth0 ...'
inside the new domain.

As a side effect of creating my first domain, dom0 loses network
connectivity as well.

Has anyone else had similar problems? It has been a while since I played
with Xen 2.x, so I may be doing something stupid.

Actually, this seems to be a side effect of starting xend. Probably has
to do with xen-br0 coming up. I am running this in gentoo.

Are you sure its not a side effect of starting xend and hence executing
the /etc/xen/network script?

This creates the bridge and attempts to transfer IP addressses from eth0
over to the bridge. I've seen it screw up on machines with ipv6
addresses in addition to the normal ipv4, but Rik recently sent a patch
for this, so it should work.

Could you just check that you have "ip" command installed? It is used
by /etc/xen/scripts/network.
If that is not it try "/etc/xen/scripts/network start" before starting xend,
does it dump any error messages?

Cheers
Gregor
