I run arch linux on a lenovo laptop. I upgraded the linux kernel to 2.26.30.1-1 today. VirtualBox 3.0.0 still starts fine, but when the virtual XP machine starts to boot, it claims there is something wrong and it needs to check the disk. It does this and then looks like it's going to boot... then the screen just goes black and stays that way forever. Meanwhile CPU usage is ~ 100%. If you do not allow the disk check operation, it will fail to boot but drop you to the "something went wrong menu," from which you can boot into safe mode. However, once booted into safe mode, window resizing (main window) does not work right, etc.

I asked on the arch linux forum about this and someone offered a link which suggested that someone had already reported this to the virtualbox bug list, but I don't see any recent reference to it, so wanted to be sure people knew it was occurring. At least with arch linux, the problem only appears when moving to the 2.26.30.1-1 kernel.

I have a similar situation.
After upgrading to 2.6.31RC2 kernel, the windows XP boots up to just about the login screen then dies with a blue screen which flashes by so quickly I can't see anything and then reboots, over and over. If I enable VT-x, the whole computer instantly hangs when I try to start the virtual machine, but that is not new, it has been doing it since v2.2.

My Window7 and Ubuntu 9.04/32bit virtual machines work fine.

Host is Ubuntu 9.04, 2.6.31-RC2 kernel, on an Intel Core2 Quad Shuttle system.
VirtualBox is v3.0, WindowsXP has all the service packs up to about a month ago.
