XCP-ng XenCenter
If you’re using XCP-ng, you’ll notice that you can’t use recent version of XenCenter to connect to your XCP-ng server.
XenCenter is open-source and you can download/compile your own version (from here: https://github.com/xenserver/xenadmin ). But if you just want to use, you can download a pre-compiled version from here.
You are a hero to the XenServer community. Thank you.
