Don't confuse quorum and fencing (stonith), they serve different
purposes. Basically, quorum is useful when things are working, fencing
is required when things go wrong. So regardless of quorum disk, you
still need to be able to fence. This requires that each VM be able to
call the hypervisor and force a power off.
Generally speaking, VM-based cluster nodes are good for learning, but
not production. It adds a layer that isn't needed and in HA, simple
should trump all else.

Hi
I wonder if there Best practise or how to, on how to run clusters on say VMWare.
I have built a 2 node cluster with 2 vm's I am hesitant to give rights to each
machine to restart the other node. Plus I would have to install the vmware lib
and....
So what do other people do
Quick search gives me

<< But I am not keen on doing that ..
I am working on centos 6.5
Can I use a network resource to make quorum, ie Can the node can ping the dgw ?
Thanks
