Using VB64 on WindowsVista64 Will not run Ubuntu64

Post by mrhobbeys »

I have an AMD 64 Turion 2x

When I try to run Ubuntu 64 I get this error from Ubuntu;

"This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot - Please use a kernel appropriate for your CPU."


VB 2.0.4 Win 64

Did you check the manual (chapter 1.6) to see if you have the proper hardware and settings?

Same error here. Ubuntu 8.04 wants a 64-bit CPU but only see a i686 CPU. It is Virtualbox not showing a 64-bit CPU.

It only happens intermitantly. Otherwise it runs like a champ. Might have something to do with host system coming out of sleep mode.

A complete power down of the host seemed to fix it last time. It just happened again. I will post back if I figure it out.

Check if there is a known bug for your motherboard. Maybe a BIOS update can fix this.

Using VB64 on WindowsVista64 Will not run Ubuntu64

Same problem for me. I'm running 64-bit Vista on a Lenovo T61 (Core 2 Duo T8300 CPU). I installed the latest BIOS and enabled VT-x in the BIOS. All the required settings in the VM are enabled, I think (VT-x, IO APIC, PAE/NX). I've rebooted several times, and re-installed VBox 2.10.

Any suggestions?

Strange -- it's working now. I uninstalled and deleted previous VDI files. Apparently my previous uninstalls weren't really working. I had a hard time getting Windows to really uninstall VB. After I got it out of my system, I then rebooted and reinstalled. This time everything worked fine. So maybe the problem was that I installed 2.10 on top of 2.06 or something. Anyway, I'm not quite sure why it started working, but I'm happy at this point.
