Boot process stops on virtual machine

[marvin_ita]

I've upgraded a F16 virtual machine under VirtualBox to F17, now the boot process simply stops, but the VM is not stucked: If I issue a ctrl-alt-del it goes in runlevel 6 and reboots.

I'm able to boot in rescue mode. I suspect something network related is stopping the boot process: sendmail agent takes a full minute to start and just before the boot process stops I can see high activity on the virtual ethernet card. I tried to disable sendmail from rescue mode and to disable the virtual network card in Virtual Box, but nothing solves the problem.

Removing the quiet kernel parameter doesn't show anything more... any ideas?

Thank you

SOLVED: I never think at the most easy solution: after changing video driver from VBox specific to standard Vesa everything works. Strange I had the problem even booting in runlevel 3......

How do you change the video drivers? Are you able to run the "real" Gnome 3 or just a fallback version of it?

Actually, I use KDE. I've edited /etc/X11/xorg.conf and changed drivers from 'vboxdrv' (if I remember correctly) to 'vesa'. The problem with VirtualBox graphic drivers is that the xorg server version provided with F17 is still unsupported at the moment.
