Document that and we're getting there.
The documentation in the current patch series says

The mssim backend supports snapshotting and migration, but the state
of the Microsoft Simulator server must be preserved (or the server
kept running) outside of QEMU for restore to be successful.

mssim today lacks the functionality of marshalling and unmarshalling the
permanent and volatile state of the TPM 2, which are both needed for snapshot
support. How does this work with mssim?
