Longtime sysadmin here and in light of Broadcom's...ermm... decisions, I decided to boycott ESXi in the homelab. I thought XCP-NG might be a fun way to go so I went all in. There are so many odd limitations and unusual workarounds that it's no longer feasible.
-
Max VHD disk size is 2TB. The workaround is that you can make several 2TB volumes and then, inside your guest and then use LVM to group them. I decided that to sidestep the 2TB limit, I'd create a 12TB raw disk.

I have had zero luck getting passing through USB drives to my VMs
-
The networking is inelegant compared to vSphere. Perhaps Proxmox is better but I haven't spent much time with that hypervisor yet.
-
Many industry standard appliances won't work in XCP-NG - believe me I tried. I looking at things like Clearpass and other Lab environments such as Eve NG. I'm sure there are others I'm not thinking of.
I think I'll move onto Proxmox, but I only have 1 server, so migrating is going to be.... interesting.
Funny enough, now with wanting to move off, I'm having to come up with interesting ways to migrate that disk to qcow2. It should be possible, but I'm putting a lot of faith in a conversion process that I don't trust yet.
Yes, XCP-NG's platform is improving and the community is growing. I enjoy how vocal the devs are and that they stand behind their product. I think it just needs a bit more exposure to get the support it needs from other industry systems to make it a viable contender.
