Hi, and thanks again for the reviews.

I thought this was right :-) Why do you believe it to be wrong? L1 wants to add vmcs12->tsc_offset to its own TSC to generate L2's TSC. But L1's TSC is itself with vmx->nested.vmcs01_tsc_offset from L0's TSC. So their sum, vmx->nested.vmcs01_tsc_offset + vmcs12->tsc_offset, is the offset of L2's TSC from L0's TSC. Am I missing something?
