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?
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......
