<![CDATA[What OS is XCP-ng 8.3 based on?]]>Is XCP-ng 8.3 based on CentOS 8.5 or something else? I'm having problems getting NUT to work and I'd like to try to get it working on the "parent" OS first.

I absolutely understand the point regarding datacenters. I am using xcp-ng for years in smaller - non datacenter - environments and its great. Therefore I added the nut packages (8.2 and 8.3) and it works like a charm. It's installation is well explained in:

https://xcp-ng.org/forum/topic/4300/performing-automated-shutdown-during-a-power-failure-using-a-usb-ups-with-nut-xcp-ng-8-2/13?_=1742229073030

However, I agree with @Kajetan321 that it would be great if the nut package could be included in the standard "updated" packages repo since its added quite some benefits (imho) for "smaller" IT environments. However, I do not know how much effort it takes to maintain that.

However, if there's a way that's relatively universal, it's doable with the help of the community (ie contributions are very welcome and we'll review it seriously)

Separately, is there any planned work on officially integrating support for Uninterruptable Power Supplies and XCP-ng 8.3?

Dom0 should be considered as a black box and any modification should be avoided as possible.

Maybe some cleanup remains. . .

XCP-ng is a distro by itself. You can find non-critical packages coming from CentOS 7, but only a part of it. The kernel, Xen, OVS and many other critical stuff is packaged by the XCP-ng project itself.

Regarding packages, you should take a look at https://docs.xcp-ng.org/management/additional-packages/
