(If I don't, Fedora crashes during the boot process.) Anyway, I am not reporting this crash but the fact VirtualBox won't remember the VT-x/AMD-V setting. Each time I restart the virtual machine, VT-x/AMD-V is enabled. Thus, before each start I have to manually disable it. This is tiresome. defect closed other VirtualBox 3.2.4 invalid Linux Mac OS X
