One test that would be also nice to have at some point would
be vepc test. It's not exceptionally hard to ramp up KVM:
https://lwn.net/Articles/658511/
Hmm... perhaps this type of kselftest should be part of the
series that Paolo is upstreaming because otherwise we are
dependent on non-upstream QEMU to test those changes.
Looking back, this would have been already good idea to ramp
up when the original KVM-SGX series was upstreamed because not
that many have motivation to self-compile QEMU (I did but thinking
about potential larger coverage).
