VirtualBox crashes guests on host shutdown

[myxiplx]

When I shut down Ubuntu, VirtualBox appears to make no attempt to perform a clean shutdown of my windows guests. The program just closes instantly, crashing the guests.

VirtualBox needs modifying to start a proper shutdown of all guests when the host shuts down, and to block shutdown of the host until all guests have performed a clean shutdown, similar to the way Gedit in Ubuntu causes a warning dialog to appear if a file has not been saved.

I'm having the same problem when Ubuntu 8.04 is the host and Slackware 12.2 is the guest. The Slackware guest has been working just fine since about v1.6 of VirtualBox. It survived the upgrade to 2.0 and to 2.1, but the latest update to 2.1.2 has made it crash each and every time on shutdown.

Strangely I'm not having the same problem when running a Windows XP guest.

I have attached a log file as the error message recommends, but won't bother with the PNG file since it's just an all-black 1024x768 image.

Slackware 12.2 guest crashing on shutdown under VirtualBox 2.1.2 running on Ubuntu 8.04 host

Further investigation: I reinstalled Slackware 12.2 from scratch under VirtualBox 2.1.2. It does not have the crashing problem when shutting down. It seems that some subtle incompatibility in the virtual machines themselves is involved.

ttmrichter: your observation doesn't belong here. Reread the original defect description.

Your problem is discussed in ticket #3124. Add your comments there please. I'll remove them from this ticket.

Please reopen if this problem is still current with the latest release (VBox 3.0.8).
