VERR_SSM_UNEXPECTED_DATA when trying to start saved VM

[AnrDaemon]

Code: Select all

Failed to open a session for the virtual machine Windows XP.

Failed to load unit 'HGCM' (VERR_SSM_UNEXPECTED_DATA).

Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

Is there a way to start it? I'd very much like to NOT lose the session.

This seems to be the relevant part.

A VM in a saved state is intended to be continued only in the same VirtualBox version. It often works between different versions, but is not guaranteed to. If you updated or downgraded the VirtualBox version, go back to the previous version, continue the VM and shut the guest OS down properly.

Welp. Thanks. I think I'll drop it then. As much as I dislike the idea, changing VB versions back and forth is probably a longer endeavor than restoring the client session.

[scottgus1]

Just keep in mind that if 'restoring the client session' means getting the guest running and 'NOT lose the session', then you can't do that if you continue using the upgraded Virtualbox version while the guest is save-stated under an older version.

If you don't want to downgrade (takes 5 minutes?) then you have only the option to Discard Saved State (right-click the guest in the guest list). This will result in the guest losing all unsaved-to-disk data that was in the saved state, and the guest will reboot as if it was powered-off without shutdown. Data will be lost.

An uninstall and reinstall of Virtualbox costs only a few minutes. Just depends on how important is the data that was desired in the OP to not be lost.

[AnrDaemon]

"Restoring" means getting the session to the same state from clean boot. It's not problematic, just tedious. Mainly why I were using "save state" rather than shutdown.
Should probably have used hibernate. But I recall I've had issues with hibernation of Win XP in a VM.
