I am currently running a 3 node cluster (oes2sp2 Linux) connected to an EMC SAN. This cluster was commissioned, fully patched, etc 250 days ago. It's been running smoothly and hasn't missed a beat :-) The nodes are bare-metal installs.

Now I've been tasked with investigating the possibility of virtualizing the nodes using VMWare (and making use of VMotion).

This will give us the ability to have 6 virtual nodes rather than 3 physical nodes.

What is the general feeling of the community with regards to:

1. Virtualizing cluster nodes
2. How complex is the setup on VMWare
3. Could I do a rolling migration from physical to virtual

Many thanks in advance for any comments, tips, advice, etc
