@dinhngtu it still wouldn't boot with the correct template. That said, I have been testing other VMs which were created on xcp-ng, with the correct templates, and get better performance out of them when they are migrated to a hyper-v host. I believe that this is related to SMAPIv1 limitations - which are known and being actively worked on with SMAPIv3. Unfortunately for us at this point, xcp-ng may not fit our business - hopefully one day soon it will be, but until then, it is what it is.

I'm taking another look and it looks like the tools may be under another name... xen-tools I may be going blind at this point if I've missed it this many times.

@kulmacet Can you recreate this with other VMs, or just this specific oracle linux VM? I would spin up a new debian VM for example and shut this problematic VM off, and see if the issue happens with this VM as well. Outside of that, it's really looking like a hardware issue. Also, double check the ILO and BIOS firmware are at the latest. I can almost guarantee it shipped with ancient versions, and many issues like this have been patched relatively recently.
