I'm having this same issue on a fresh install of 8.2.1. Either installing the xolite.html file on the host or going through lite.xen-orchestra.com. I thought, and have seen in screen shots, that XO LITE would at least let me configured some basic networking functions like bonding. But the only thing available to me is Dashboard, Tasks, and VMS.
Also the "Patches" section just spins forever.
If you are just staring out with XCP-NG how are people configuring basic functionality of the HOST before going the route of installing Orchestra?
I'm a long time user of Citrix Xenserver 6.x and 7.x and have done a lot of things on the CLI. In fact that is how I installed XCP-NG 8.2.1 was via a PXE boot to bare metal. But some tasks I always went back through xencenter to configure because there wasn't an easy way to do it on the CLI w/o writing a ton of code.
So, what is the purpose of XO Lite on 8.2.1 if it doesn't do anything? It does look nice!
