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.

Log files

Log files from xend start including ifconfig before and after starting xend.

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

After cleaning up some problems it seems to be working now.  I'll try to drop the -1 karma when bodhi is back up.
