RAC on VMware - NMP recommendations?

The following question just popped up on Oracle Community:

Hi all – I had a request from a customer today.  He’s looking for any published recommendations/best practices for running Oracle RAC on VMware vSphere, but using NMP, not PowerPath.  Specifically, he would like assurance that running NMP settings for Round Robin (changing maxiops to 1) are fine, and there’s no need for anything like Fixed Path at all. I’ve looked all over all our sites to no avail, and can’t find anything specific to this on the VMware documents either, but to be honest it’s the first time I’ve gone looking for this topic.  I’m sending to a larger audience in hopes that others have had this question already.

First question – is there anything anyone’s aware of published out there w/r/t NMP settings for running virutlaized RAC?

Second question – any known issues with Round Robin settings using NMP (assuming OEL Linux) within nodes in a virtual RAC cluster instead of using PP/VE?
