Also interesting to me is that the guest that seems to trigger this
is Debian stretch 64-bit with an older kernel that does not have
L1TF mitigations. I have asked the owner of it not to upgrade their
kernel yet because I think when the guest kernel behaves correctly
it will stop crashing the host and we'll learn nothing.

Sadly I cannot reproduce this on demand.

Cheers,
Andy
