I manage a production standalone CGP instance on FreeBSD on VMWare and a 
production gonna-be-a-micro-cluster node running on a FreeBSD VM on 
XenServer. I HAD a second node up for a month of smoketests with one 
domain for that wannabe-cluster on a FreeBSD VM on KVM/CentOS. All 
worked smoothly with that until my boss said "why are we virtualizing 
these CGP nodes anyway?" and we realized that the reasons we had 3 years 
ago for wanting to do so were no longer valid. We're returning to 
running on hardware.

So I can't say for sure that a cluster on VMWare would work, but a 
single server does and a microcluster on somewhat disparate VMs works as 
well. CAVEATS: We don't use the VoIP/SIP/Signals functionality (except 
to the extent that CGP abstracts XMPP down into the same modules) and I 
only set up the simplest possible cluster: 2 nodes, both combined 
front+back.
