Has anyone had any dealings recently with the cloud frontends as 
follows: Eucalyptus, OpenNebula, or Nimbus? Reading their sites I see 
some pros and cons but I would like to hear first hand experience of 
users if possible. I know I can (and probably will) ask on their lists 
but I would like an unbiased review hence why I ask here. Two points I 
would like to hear on is: 1. How well do they handle HA setups with a 
SAN and such. 2. How do they work with existing setups (remember I have 
spent months perfecting the bond + vlan trunk etc on our setup).
Thanks in advance.
