Hi,

I have a general question.
How can I make VirtualBox boot a guest from scratch instead of resuming it? In other words, I'd like to make Virtualbox forget about the guest's saved state.
I know, this would be like pushing the physical reset button at a device which is currently suspended to RAM, but for the current OSs this is usually not a big deal.

The reason why I'm asking: all of my guests (Fedora, Win10, Win11) with a saved state (i.e. they all were not expicitelly shut down) are now crashing when I try to start (i.e. resume) them.
All the guests which were shut down still boot properly.

As far as I remember, I installed one Virtualbox update (6.1.32) in the meantime. Before that I was on 6.1.28 (not 100% sure). I suspect this update being the root cause for the behavior.

Thanks

Yep, that'll do it. Saved states don't survive version changes.

Right-click each VM and click Discard Saved State.

If discarding a VM's saved state will be bad, you can downgrade to the previous version, restore the VM then shut it down properly. Then upgrade again.

Oh, great! Thanks and sorry for the dumb question...

Although I use Virtualbox since years, I never felt the need to try out that function before. As I'm running the German version, the translation of the menu item also sounds very common... not exactly related to the saved state.

But, now, after having discarded the state, at least my Win10 guest messed up the display driver... I see a black screen with some weird pixels on it. After few minutes of waiting, Windows restarts automatically (running into the same issue again).

Any ideas?

Please start a new topic for that VM, with a VM log:

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

Right-click the VM in the main Virtualbox window's VM 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.
