I get the following error after upgrading via Migration Assistant my laptop from a 2-core to a 4-core processor:

cpum#1: X86_CPUID_FEATURE_ECX_MOVBE is not supported by the host but has already exposed to the guest [ver=17 pass=final] (VERR_SSM_LOAD_CPUID_MISMATCH).

How can i resolve the same?

The solution may be as simple as clicking the big yellow "Discard" button, which will delete the saved state (same as pulling the power cord).
