I discovered about a few months ago that XCP-NG does not support NFS shares which was a huge dealbreaker for me. Additionally, my notes from my last test indicated that I could not mount existing drives without erasing them. I’m aware that I could have spun up a TrueNAS or other file sharing server to bypass this, but maybe not if the system won’t mount the drives in the first place so it can pass them to the TrueNAS . I also had issues with their xen-orchestra which I will talk about below shortly. They also at the time, used an out of date CentOS build which unless I’m missing something, is no longer supported under that branding.

For the one test I did which was for a KVM setup, was my Home Assistant installation, I have that running in Proxmox and ccomparativelyit did seem to run faster than my Proxmox instance does. But that may be attributed to Home Assistant being the sole KVM on the system and no other services running (Aside from XCP-NG’s).

Their Xen-Orchestra for me was a bit frustrating to install as well, and being locked behind a 14 day trial for some of the services was a drawback for me. They are working on the front end gui to negate the need for this I believe, but the last time I tried to get things to work, it didn’t let me access it.
