@Davidj-0 From what I understand, the xcp host must already be turned on. The VM will only start at the defined time, when for some reason, it has been turned off previously.
My plan was to have the servers power up when they received power. Then the "auto power on" XOCE VM would start and, via scheduling, power on other VMs in a predefined order.
Does the "Appliances" feature only exist in the XCP-ng command line or in the XCP-ng Center?
According to this link this feature does not exist on XO: https://xcp-ng.org/forum/topic/6311/managing-vapps-with-xoa
