Setting the XenServer pool to allow Auto-Start
Gather the UUID’s of the pools you wish to auto-start.
To get the list of the pool’s on your XenServer type:
xe pool-list
Copy the UUID of the pool. If you have just one server, it will still have a pool UUID as seen below:
Then type the following command to set the pool or server to allow auto-start:
xe pool-param-set uuid=UUID other-config:auto_poweron=true
Note: *Replacing UUID with the UUID of the XenServer or pool.*
Important to switch this off if you are going to use HA, DR and Pool upgrade functionality because the auto-start function interfered with High Availability , Disaster Recovery and Pool upgrade.
