On closer inspection: the problem is not limited 13.0-RC3.

If I save the state of a guest whilst 12.2-RELEASE-p3 runs:

* no problem after starting from the saved state.

If I upgrade to 12.2-RELEASE-p4, restart the guest then save the state, 
I can start from the saved state, however:

* no response to keyboard input

* ACPI shutdown does not begin a shutdown routine.
