CPU not recognized when installing ubuntu amd64 in VirtualBox

corkscrew22 · 03-30-2009, 04:54 AM

I am running Hardy Heron 8.4.2 amd 64

VirtualBox version 2.1.4 for amd64 cpu ( installed by downloading deb from vb web site and double clicking file)

I am trying to in install Hardy Heron 8.4.2 amd 64 on a virtual machine. Every time I try and install I get the following message
This kernal requires an x86-64 CPU, but only detected an i1586 CPU. Unable to boot - please use kernel appropriate for your CPU.

I have virtulization enabled in the bios. I have enabled in advanced settings, ACPI, IO APIC, VT-x/AMD-V.

This has nothing to do with your bios, nor your real cpu. It has to do with the cpu that virtualbox is emulating. Remember: no piece of hardware inside a vm is real. I think (but don't remember exactly) that the latest versions of virtualbox can emulate an x86_64 cpu, previous versions can only emulate x86, no matter what the host cpu is. You might need to set it up on the options somewhere, I haven't it installed so can't check.

Indeed, i92guboj is right: the problem is not in your hardware nor in Hardy Heron: it is in your virutalbox. Installing Hardy over it your cpu has no direct dialogue to hardy, save those that the virtual box translates in between them.

{ During the coldwar few "minor" agents/assets were executed in the hands of enemy, merely because their pleadings relied mainly on poor interpreters.

}

If you change into better virtual handler you will have no problem installing it as your hardware side is truly very strong to run a hardy. You don't even need to stipulate a NOAPIC switch since you are running a dual-core.

Good luck.

Hope this helps.

You installed the nonfree version right? Most likely, since you downloaded from its web site. The 100%-open-source version is missing some features.

Wikipedia says VBox supports 64-bit guests since 2.1.0, but I can't tell you how. Once the site is back up I would ask the documentation there.

Which virtual handler would you recommend?
