"Correct" way to manage UPS?
Now that I've gotten more serious with my XCP-ng setup, I'm trying to do my UPS system in a better way. Also, I haven't bought new UPSs. The ones I have, they're basic consumer and the batteries are EOL.
So I was thinking about getting an APC tower unit. Then using something like APCUPSD or NUT to control it. I've heard about installing it on the dom0, but is that the "correct" way? I'm not really a fan of installing packages on the dom0.
I feel like I could also use the XAPI to issue shutdown commands. Or have each guest respond with NUT/APCUPSD.
How do I manage UPSs and XCP-ng.
