I recently stumbled across the fact that all EPYC as well as all newer high-core-count Intel CPUs are actually multi-chip modules and count to some vendors like Oracle with their database as multi-socket systems even if you use only one CPU socket and are therefore forced to license more sockets or use single-die CPUs as you're not allowed to have more than two sockets in the standard edition 2 - at least on non-Oracle hardware. For me, this was shocking because the information about a single CPU type is not easily to get, Intel ARK does not show this and I was unable to find out how a single EPYC does this in the lower core count modules.

For PVE, this is actually quite easy, the licensing agreement states clearly socket, so we're fine here, yet what about other products besides Oracle databases? What is your experience with this with virtualized software that uses processor / socket licensing?
