[Linux-cluster] clustering inside of vmware -- fencing

[Kevin Anderson]

There is a new implementation of the fence_vmware agent written in
python in the GIT tree:
http://git.fedorahosted.org/git/cluster.git?p=cluster.git;a=tree;f=fence/agents/vmware;h=d07bfd7a8d6f445f15f793626cf493a9edf11833;hb=refs/heads/master

This one uses the new libfence python infrastructure and hopefully does
what you need.  Check it out and let us know.
