Rebooting CentOS guest causes critical error

Postby paulcybercitizen » 26. May 2019, 18:10

I recently installed VB on a Windows 10 PC, and made a CentOS 7 guest. Today, rebooting the guest caused VB to report a critical error. I'm new to VB and CentOS, and would very much appreciate help in debugging.

The host is a Dell XPS 8930 running Windows 10, and the only connected externally via WiFi. The version of VB is 6.0.8 r130520 (Qt5.6.2)

The guest is CentOS 7 downloaded a few days ago.

I rebooted the guest using the "reboot" command in a terminal window, and while it was coming back up, VB reported a critical error and recommended closing the guest and referring to the VB forum. I attached the files mentioned in the message, and the output of the VB command showing the guest configuration. Any help diagnosing the problem would be welcome.

regrettably it seems the part of the log that would have shown the error has gotten truncated. Please zip the log, it will fit if zipped.

Just recently we resolved another issue that was getting a VERR_PGM_HANDLER_NOT_FOUND, and again it had to do with restoring a saved state. Take a look at the thread VERR_PGM_HANDLER_NOT_FOUND error and see if shutting down the VM helps in your case too...

I launched the VM again, and this time there wasn't any error. So is the solution is to never pause the VM? I.e. if I'm going to power down the host, I should first shutdown the guest instead of pausing it?

Until the issue gets addressed, I'm afraid that yes, you should shutdown the guest. It's the best practice after all...
