What is the différence when the VC is physical because when I started the VC VM, it took control of everything and everything 'came back' automtically. Looks like HA agent of each ESX gave up after a few minutes trying to heartbit his friends. Then it is the VC that reinitialized agents on every ESX one by one (logged on VC). Am I right ? Best regards, Cyril Thanks,

Well because all VM's were shutdown by HA, the isolation response kicking in means that the startup will not occur automatically if all servers are going down. they are all waiting on eachother to start up the VM's they closed down...

I have my VC in a VM (ESX3.5U1) and the whole network went down for 5 minutes. All VM on all nodes shut down (Isolation response) but none went up when network back until I turn un the VC VM manually ! So Why ? Best regards, Thanks, Cyril Nice article, congratulations,

Just to clarify, when does the 14-day trial license come into play? If the licensing service is unavailable? Will that prevent ESX server from starting? Thanks, Great, thanks for the quick reply.

Just one question... Suppose there were a situation with power where all the ESX hosts and VirtualCenter went offline. And when they come back up, the VirtualCenter service doesn't start properly... This table seems to indicate that ESX should start with a 14-day trial license, but what about the VMs? Do they start automatically, or do you have to connect to the ESX server manually to start them? Does it depend on how HA is configured? Thanks, That table is a great resource!
