Greetings,

Before posting a bug report, I'm wondering if anyone else has had the following experience. Searching both this forum and the bug pages hasn't turned up anything definitive.

I'm running Vista 64 host, Virtual Box 3.0.6, and Ubuntu 64 guest. Regardless of whether shutting down the guest or trying to save state of the guest, the VM would always end up in an abort state with the dialog box "VirtualBox GUI has stopped". After reading about similar issues, and just trying turning on/off various settings of the VM, I have discovered that the issue is using NAT networking. If I change to the Bridge adapter (Dell wireless), the VM shuts down cleanly, or, if saving state, the VM actually succesfully saves state and is able to restart using the saved state.

Is there something particular about NAT that needs to be done on the host Vista side that would allow shutdown to work? Or is this expected behavior with NAT networking. Or is this a bug to be reported?

Thank you for your time,

I use NAT on several OSes on Vista host and do not see this problem. But there was an issue with 32 - 64 in version 3.0.6 and I hear there is a fix on the way. Maybe you should wait a bit to see if the maintenance release solves your problem.
