If the nested hypervisor doesn't intercept INTR we don't support it anyways.

That's a bug.

It's a question of how accurate we want to be.


Really, pushing the whole nesting state over is not a good idea.

Isn't the entire state just one bit? Everything else should be saved to guest memory.

It's not. We can't use the guest memory for hsave because then the guest could break the l1 state, so a malicious hypervisor could break us.
