The AMD Opteron family has different xlevel levels depending on the generation. I looked up Gen1, Gen2 and Gen3 hardware and adapted the levels according to real silicon.
The reason this came up is that there is a sanity check in KVM making sure that SVM is only used when xlevel is high enough. Using real hardware levels, they now are. Reported-by: Bernhard M.
