Mandriva 2008 has the guest additions for VirtualBox 1.5 installed by default. The openSUSE 10.2 kernel suffers from the race condition mentioned above. The Ubuntu 6.06 Server and 6.10 kernels suffer from the race condition mentioned above. Kernels 2.6.18 to 2.6.18.2 contain a race condition (which was unfortunately backported to the Ubuntu 6.06 Server and 6.10 kernels) that can cause boot crashes in virtual machines.

Generally, all 2.4 and 2.6+ kernels work however, we recommend 2.6.13 or above for better performance. Install a 3rd party VESA graphics driver or disable hardware virtualization.
