KEEP ORDER AFTER AN UNPLANNED SHUTDOWN
Secure the infrastructure of your Pool to a blackout of their VM, for example, caused by a power failure.
Plan an auto-run policy establishing a delay for the start of each VM. During the delay, all the resources and services that the machine needs are enabled during the delay, and ensuring that they are ready at boot time
XenToolBox auto-run function gets priority over the auto-start function that Xen sets by default. When we include a VM in a XenToolBox boot planning, the auto-start function gets deactivated. In the same way, when a VM is deleted from a XenToolBox boot planning, the auto-start function that was set in Xen, gets re-activated.
