I actually don't think paravisors make *ANY* sense for Linux.  If you
have to modify the guest, then just modify it to talk to the hypervisor
directly.  This code is... modifying the guest.  What does putting a
paravisor in the middle do for you?

It might help with binary drivers, but we don't do upstream kernel work
to make silly binary Linux drivers happy.

So, no, there's no similar TDX solutions planned, at least for Linux
guests.  Unless I missed the memo.  Kirill?
