virtualbox.org

Host: Windows 10
Guest: UBUNTU 20.04

Crashes everytime on Power Off -> Restart

Kindly help.

Start the guest from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the guest from within the guest OS if possible. If not possible, close the Virtualbox window for the guest with the Power Off option set.

Right-click the guest in the main Virtualbox window's guest list, choose Show Log. Save the far left tab's log, zip it, and post the zip file, using the forum's Upload Attachment tab.

Attached the log.

One screenshot also attached for the crash. (Could not attach screenshot!)

This happens when the 3d Accel is selected, otherwise restart works.

Please review.

Another major problem is that after installing the Guest Additions 6.1.12, and after restart, the shared folders goes missing from the folders. I've to re-run the GA software again and every time to get the shared folders back in the folder listings!
Looks like the kernel is not replaced properly after restart.

Please help!
Thanks

Look slike the auto mount option does not work...

Need to run the command every time I reboot to access the shared folder:

sudo mount -t vboxsf VM_Shared /media/sf_VM_Shared/

A new Nvidia driver version for your host video was put out with a file that has a portion of its security signature incompatible with Virtualbox's hardening. (The jury is still out on whether it is Nvidia or Virtualbox at fault, or both.). Get on with Nvidia's help or forums.
