Snow Leopard (kernel 64 bit) crash after starting VB 3.0.6

I just upgraded to VirtualBox 3.0.6, that is supposed to support Snow Leopard 64 bit kernel, but as soon as I start my virtual machine (Win XP SP2 - 32 bit), my whole system crash and my Mac reboot automatically. I have Snow Leopard 10.6.1. I have a 64 bit processor, 64 bit EFI, 64 bit kernel mode boot, and 64 bit kernel (everything is supported). When I boot in 32 bit kernel mode, VBox works fine.
Thanks,
Tommy

Post a bug report with the Crash Report attached. Also the Vbox.log file might be interesting.

Is VT-x enabled?

I am not sure about exact what VBox installs but I have a feeling that it installs a kernel extension. Regardless of booting into 32 or 64 bit mode you can run a 64 bit or 32 bit application the limitation comes in with kernel extensions, they have to run as part of the kernel and have to match it. A 32 bit extension in a 64 bit kernel or a 64 bit extension in a 32 bit kernel will cause a crash.
I currently run a couple of 64 bit OSs under VBox on OS X with the 32 bit kernel.
I have not seen any virtualization software for OS X that runs in 64 bit native mode. Both VMWare Fusion and Parallels are 32 bit, it will likely be a while before they go 64 bit native. I would expect VBox to be the first.

VB is already 64 bit for Mac OS X 10.6 since 3.0.6. This is one of the first reports where it doesn't work. Another user had the same problem but he ran 3.0.4. After the upgrade to 3.0.6, it worked just fine.

It does the same thing on me. Crashes when running SL in 64 bit mode. The system reboot is random for me as well. It could do it at any time during the VB session with WinXP and IE8.

Is there a Fix for this ?
I`m running on a Snow Leopard 10.6.2 host with ALL 64-bit extensions and kernel working flawlessly, however Virtualbox 3.1.4 is able to reboot my machine completely, no crash, no report, straight back to POST screen. I`ve never seen an app crash like that since MSDOS days. My VM runs with VT disabled. It is also notably slower and memory hungrier than the same setup that previously ran Leopard 10.5.7
