Wondering if I can do the following. I find my self not using the server from 12am to 6am and during this time, the server is eating up power, doing a rough calc, I will be saving roughly $10 a month just shutting it down during off hours. I understand a VM host needs to be up and alive 24/7/365 but would like it if I can shut it down cleanly, then auto start at 6am.
Xen Orchestra can schedule VM shutdowns, not sure how to get an XCP-NG host to auto power up and down, depends on the motherboard and if there is an external method to get it done.
