You seem to be saying TLB miss, but thinking page fault. When there's a page fault (the shadow page table does not contain a translation for the address in question), there is that multi-level lookup by the guest kernel and hypervisor, to ultimately add a translation to the shadow page tables.

Yes, I think you've nailed it. I seem to have conflated the two issues.
