I've had this problem with Fedora 15 Live CD --- when trying to install it into the VirtualBox VM running on the Fedora 14 host. It would do the countdown, and just hang. Then I tried the DVD installation, and instead of just hanging, it politely told me that I am using the wrong kernel for this architecture. That was a clue what to look for --- I tried to install the 64bit version into VirtualBox The host was also 64bit, so I thought it would Just Work. But it doesn't. After downloading the 32bit version of the LiveCD, it worked perfectly. Then I RTFM: http://www.virtualbox.org/manual/ch03.html#intro-64bitguests which explained a lot of things for me. ;-) HTH, :-) Marko
