It would be interesting to know the interaction between the patched host and the patched guest. As a simple example, if the host aggressively flushes the TLB, the performance impact on the guest of doing the same could be lower. On the other hand, depending on how the host was patched, the loss of performance of the guest could be different when using some features.
