I have installed VirtualBox 3.0.0 on my opensuse 11.1 desktop. Installation of XP into virtual box seems to go flawlessly. When the virtual xp reboots after instalation, it hangs up during the first few seconds of boot up. I restart the virtual xp and select safe mode and I can see that it hangs up on the windows/system32/drivers/agpcpq.sys.
Apart from the RAM allotment, i think that the VirtualBox settings are all default.
