Description Lon Hohberger 2007-03-06 17:47:28 EST
Description of problem:

Fence_xvm and fence_xvmd do not correctly use the contents of

If multiple clusters are run on the same subnet without the multicast packets
being filtered, then it is possible for the following to occur:

* If another cluster has a virtual machine with the same name, it can
inadvertently fence the virtual machine.
* Due to a previous behavioral change, fence_xvmd now returns success if it has
never heard of the domain.

Both lead to false-success scenarios where a virtual machine has not been
correctly fenced.

It may be advantageous to give the virtual machine cluster the name or ID of its
parent (host) cluster in order to prevent these behaviors from occurring when no
authentication is used.

Fixing Product Name.  Cluster Suite was merged into Red Hat Enterpise Linux for
5.0.  In addition dlm, fence and ccs were merged into the cman package, so
bugzilla should reflect package name where those utilities are located.
