Hey Folks, I have some wildly disparate CPUs throughout my nova-compute environment and I'm trying to figure out the best way to find the correct cpu_model and any "extra_flags" that might need to be passed. According to "virsh capabilities" I have Broadwell-IBRS, Skylake- Server-IBRS and SapphireRapids-noTSX ... And... my attempts at finding a compatible model/flags has failed miserably. I tried getting all of the "capabilities" in one file and passing that through "virsh cpu-baseline" but that returned something completely incompatible with the Broadwell ... I looked at "virsh domcapabilities" and found that they all support "Broadwell-noTSX-IBRS" ... and nova- compute will start up using that... but, live migrations between the Broadwell and Skylake CPUs to the SapphireRapids doesn't work properly. tl;dr ... any tips on making this work with wildly disparate CPUs? -- Andy Speagle
