9884	attempting to run a 64 bits guest reboot the linux host (AMD)	zebul6		"I am running '''Archlinux 32 bits''', up to date as of '''2011-11-10'''. with a 3.1 kernel on an '''inspiron 531''' with an '''AMD Athlon(tm) 64 X2 Dual Core Processor 4400+''' AuthenticAMD 

For the record, I am able to run Ubuntu 11.10 64 bits on this box natively

'''The issue/bug''':
When I attempt to run any (either windows 7 64 bits or ubuntu 11.10 64 bits, and I think I could enlarge the list to whatever you like) with virtualbox 4.1.6, it blacken the screen and reboot the box/pc!

I was expecting this to be fixed other time but I see no improvement. This is not a new bug. It happens since at least vbox 4, kernel 2.6.39

I think it has to do with the linux kernel but I can't be sure.

''Scenario: Attempting to install Windows 7 64 bits by booting the iso/dvd''

With PAE/NX enabled with IO-APIC activated, it freezes after displaying ""Starting Windows""

With PAE/NX enabled without IO-APIC activated, it rebooted right after ""Starting Windows"" is displayed after the ""Windows is loading files"" screen

If I enable PAE/NX with IO-APIC, it reboots as soon as ""Starting Windows"" is displayed

One get a similar experience attemting to install ubuntu 11.10 64 bits from vbox (not sure about the config of the VM)

Also booting ubuntu 11.10 64 bits from a real partition with vbox in archlinux 32 bits, gives a reboot as soon as the boot process begins (after grub screen)

Also booting Windows 7 Home Premium 64 bits from a real partition with vbox in archlinux 32 bits) gives also a reboot 

I have gave up trying to use anything 64 bits with vbox because of that reboot.

I got no problem running Ubuntu 11.10 64 bits (from a real partition) from Windows 7 Home Premium 32 bits with virtualbox.
