VritualBox Whonix restoring snapshot - Error 'lsilogicsas' VERR_SSM_LOADED_TOO_LITTLE

[TNT_BOM_BOM]

Restoring snapshot of Whonix 15/14 + Vbox 6.0.4 on debian buster will give this error:

[Patrick]

VERR_SSM_LOADED_TOO_LITTLE

VirtulaBox upstream bug:

• Error 'lsilogicsas' (VERR_SSM_LOADED_TOO_LITTLE) when opening a saved session

• virtualbox.org • View topic - Problem restoring saved machine

Workaround: shut down VMs before taking snapshots.

Non-solutions: switching virtual hard disk controller to SATA AHCI due to:

• https://github.com/Whonix/Whonix/issues/274
• ATA Freeze
• https://www.virtualbox.org/ticket/10031

Maybe some other vrtual hard disk controller would be affected by neither snapshot restore not ata freeze bug?
