VM aborted while saving state

[mgrzegor]

I tried to save the state of the VM by selecting File → Close from the popup menu (invoked via a custom Host key shortcut) and, with the “Save state” radio button selected, pressing OK. At first, the VM seemed to save normally, but then the save process appeared to stop prematurely and the VirtualBox interface showed the VM state as “Aborted”.

This occurred after upgrading VirtualBox from 6.0.24 to 6.1.22. Before the incident, the VM had been running for several days and, if I recall correctly, was successfully saved and restored once, and also paused and resumed once.
