[Linux-cluster] How do I add a fence_vmware with system-config-cluster

[Ram]

Hello
We are using RHEL 5.4 on VM nodes.
When I configure the cluster using system-config-cluster I do not get an 
option of fence_vmware in the User Interface
I am able to run fence_vmware successfully on commandline , but I am not 
sure how do I put in into the cluster.conf

Can someone please help with a sample cluster.conf  or option to add in 
system-config-cluster.


Thanks
Ram
