See reply to Jiewen Yao.

As of today microvm does not support confidential computing.  Didn't
investigate yet how much work it would be to add this.  With luck it
would be just a few lines adding a config switch and hook up the
existing setup code for pc/q35 (at least for amd sev which is merged in
qemu upstream already).

Having seen how the tdx patches for qemu bend the q35 machine type to
make it fit, for example adding switches to disable pit+pic, I suspect
microvm might actually be an interesting target for confidential
computing.

take care,
  Gerd
