Hi.

My VM started to no longer allow activation by the mouse, only by the keyboard. So I decided to restart the VM (Power + Restart). When I opened the VM again, a critical error message appeared, instructing me to send the logs to them.

What should I do now? Can I continue using the VM?

I attached the logs.

Your guest had what Virtualbox calls a 'Guru Meditation'. Here is a hint to help you start to figure out what happened. Open the log in a text editor and search for the word 'meditation'. This will take you to a few lines that mention the Guru Meditation and some CAPITALIZED_UNDERSCORE_SPACED_WORDS that describe the error. Then, in a web browser, do a search using the CAPITALIZED_UNDERSCORE_SPACED_WORDS, with the text "site:forums.virtualbox.org" added to restrict searching to this forum.

Your guest's Guru Meditation was for VERR_PGM_HANDLER_NOT_FOUND, so search for 'VERR_PGM_HANDLER_NOT_FOUND site:forums.virtualbox.org in a browser.

Searches suggest that your guest started from a saved state, which is what happened:

The log wrote:00:00:03.318763 Console: Machine state changed to 'Restoring'

but something in the environment changed enough that the guest couldn't start from the saved data. Right-click the guest in the guest list and choose Discard Saved State, if you can. Then restart the guest. Unfortunately, whatever was unsaved in the guest before it was save-stated will be lost.

If you start from a full shut-down from within the guest OS, you should not have any problems. Post back if you do.

I just restart the VM and the problem is no longer occurring. I came back to work normally.

So is this an abnormality that can occur when restoring a saved VM instead of shutting down?

A saved state is a conglomeration of lots of sources of data: cpu states, disk positions, source code knows what else. If something changes, then a saved state could become out-of-date and unusable. No real way to predict when it might happen. Hopefully it is abnormal on your PC. It does come up in the forum but not often.

So it's just a computer thing. Don't trust unsaved important data during a saved-state, just like don't trust important data without backups.
