Okay sorry, maybe I have been lazy at something else too like skipping the documentation. I'll do more research and learn to use properly.
Thanks for pointing it out 
And another for making such a great product. We have been using from sources until now, because in our University its a hard process of getting any licenses approved for purchase. Maybe in the future I can do something about that. 
I hope that the next XO UI includes way to handle large amount of VMs easily.
Currently, we have hundreds of VMs running. If for example, I want to start, stop, migrate or w/e large amount of them with a single command, that is only possible from the Center. XO only shows 20 VMs at once.
For us, there is also second problem with using XO only, because XO is hosted on the Xen server itself, so if Xen server is in maintenance then we cannot access XO interface - of course that could be avoided by adding isolated machine running XO, but up until now we have been to lazy to do it - mainly because of the problem described above 
Otherwise XO is a great product, and we use it for everything else.
Hello,
We are using XCP-ng at our University, and are looking to purchase either Radeon Instinct MI50 or MI60 GPU:s (running on HPE ProLiant Gen10).
So am I correct to assume that vGPU works for these AMD cards? Just want to confirm, as the hardware costs quite a bit
