March 23, 20206 yr I've tried multiple combinations of settings, but I can't get the emulated cpu setting to stick when I create a vm. When initially creating the vm, it lets me select emulated with no errors, but then later after the vm is created the setting changes itself to Host Passthrough. And if I edit the settings and change back to emulated I get an error, "Execution Error the CPU is incompatible with host CPU: Host CPU does not provide required features: svm". I don't want to do Host Passthrough cause this processor only has 2 cores and I may want to run multiple vm's on it in the future. This is my secondary server, and will ultimately be a backup server, so I don't care that much about cpu performance which is why I chose a 2 core unit. It's a celeron G3900, all virtualization technology is supported and turned on in the bios of my motherboard which is a SUPERMICRO MBD-X11SAE-M-O, running the latest bios revision.

Picking host passthrough shouldn't prevent you from running multiple VM on the same cores. Perhaps you are confusing that with PCIe passthrough?

OK, I thought that was a problem. So I thought that if you passthrough a core, the intention is for that core to be dedicated to the vm. If that's not the case, then I guess I'm fine. Thanks,
