How to Setup XenServer 6.x to Auto-Start Virtual Machines
Setting the XenServer to allow Auto-Start
Gather the UUID's of the pools you wish to auto-start.
To get the list of the pools on your XenServer, run:
xe pool-list
Copy the UUID of the pool. If you have just one server, it will still have a pool UUID.
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.
Setting the Virtual Machines to Auto-Start
Gather the UUIDs of the Virtual Machine you want to auto-start by running:
xe vm-list
Note: This generates a list of Virtual Machines in your pool or server and their associated UUIDs.
Copy the UUID of the Virtual Machines you want to auto-start, and run the following command for each Virtual Machine to auto-start:
xe vm-param-set uuid=UUID other-config:auto_poweron=true
Note: Replace UUID with the UUID of the Virtual Machine to auto-start.
