Description Orion Poplawski 2008-08-12 11:37:17 EDT
Description of problem:

With the xen-3.1.2-5.fc8 update, networking on the host is shutdown when xend starts.  It looks like I end up with a peth0 interface with no IP and a tmpbridge (or similar) with the original IP of the host.

Okay, scratch the update part.  Looks like the culprit may have been a failed
attempt to install a F10 guest at the same time as I did the update.  Reverting
to 3.1.2-2 did not help.  I also tried to remove the config for the newer F10 guest but that didn't help.  Now I'm left with a F9 x86_64 guest that had been working for a while but now seems to crash the networking when brought up.  I'll attach the config.

Orion: if you think the update didn't cause this, could you kill the -1 karma in bodhi

Your networking issue is strange. This:

  device eth0 already exists; can't create bridge with the same name

suggests that when this:

  create_bridge ${tdev}

is called, that tdev=eth0; but clearly from your ifconfig output, tdev=tmpbridge

dunno, try add "set -x" to network-bridge and looking at the output in xend-debug.log
Comment 5 Orion Poplawski 2008-08-15 17:18:43 EDT
After cleaning up some problems it seems to be working now.  I'll try to drop the -1 karma when bodhi is back up.
