Guru Meditation on Vista 64-bit

Post by dusan.zervan »

I've created virtual machine using Clonezilla backup of real machine with Windows 7 RC 32-bit and Ubuntu 64-bit installed. There is GRUB boot manager installed. Strange thing is, that launching Windows 7 will crash VirtualBox, if VT-x support is enabled. If I disable this, then Windows 7 will start, but Ubuntu will not, because it is 64-bit.

I don't have problems with VT-x on other virtual machines (many kinds of Linux, Windows XP) - only problem is this multi-boot machine. Is this a bug?
