It happens after shutdown and reboot. The VM just goes into a weird state with "Guest hasn't initialised the display (yet)" error. If I create another VM with the same configuration and use the same boot disk it works fine. So, if it's not NVRAM, I am not sure what could it be which stays with VM but is not a disk.
