Hello,
I updated my patch for fence_xvmd to add network interface select option
posted before.
This patch fixes the following issues ATST:
1. fence_xvmd selects wrong network interface to listen on if host has
multiple interfaces and target interface is not for default route.
As a result, fence_xvmd does not repond to fence_xvm's request.
2. fence_xvmd cannot start if default route is not set.
The following patch is for cluster-3 HEAD.
The same problem exists in cluster-2 (rhel5's cluster) and I opened
bugzilla bug for that version: rhbz#459720.
