Are you talking about vNUMA and the numa balancing in guest?

There's no page table migration in host. Only page table is modified and
page is migrated in a single host.
Live migration also doesn't copy the secondary page tables (i.e.
EPT/NPT) to the target. Instead, it's rebuilt in the target side.
So, I don't quite understand your question here.
