If HA is configured and enabled the "stopped" VM's are suppose to be moved when the host goes offline (if unexpected) - now I have seen this reaelly does not seem to happen as expected.
You should opne a case with VMware this catalog issue is something they do need to work out - and will only do it if people are opening lots of cases on it.
(Also keep in mind if you place a host in maint mode - even if you select the move offline vm's - you will have a window where VCD operations fail) -- As the host is "in an invalid state" while it is going into maint mode, but the catalog vm's still exist on it until the VERY last set of operations to place in maint mode. (A major issue if you have a dense system)
Example:
Host A has 100 running VM's, 200 catalog VM's
When you tell the host to go to maint mode it might take an hour+ to get all the running VM's moved - during this all catalog VMs are still on this host and can not be used to instantiate new VMs... Do you have an issue window. (To solve we have a VCO script to place hosts in maint mode in a more cloud friendly way)
