12458	Vbox 4.3.4 not starting 64 bit guests	Nils		"Debian 64 bit host, debian 64 bit guest.
Vbox 4.2 ran everything fine
Vbox 4.3.4 didn't start the 64 bit guests. It also (in the settings) didn't even have the option of selecting 64 bit guests. Starting the VM let it run Grub, and then it hung after the message about loading the initial ramdisk. Compiling the kernel modules didn't change anything (except allow the kernel module to load via modprobe)
Downgrading to 4.2 ran everything fine again."	defect	closed	other	VirtualBox 4.3.4	worksforme	64bit		Linux	Linux
