Ubuntu

The kernel requires the following features not present on the CPU

Asked by SDECHA

Under VmWare Workstation (Version 5 or 6) it is not possible to start the lts 8.04 Server .
The complete Message is: The kernel requires the following features not present on the CPU
0:6
Unable to boot - please use a kernel appropriate for your CPU

This messages comes on different Laptops and Desktops with VmWare or VirtualBox.
What is the reason for this?

We had to restart the System in recocery mode and installed the linux-generic kernel. Now it's working.

You most likely have the wrong server image.

Try using the i386 image or the amd64.

Hello,
i downloaded the ubuntu-8.04-server-i386.iso and installed this Version under VmWare-Workstation 5.5.6 ,Version 6 and VirtualBox but it was the same result (same Message) on Laptops and Desktops.
All Systems are 32 Bit-Systems with single Prozessors.

I linked your question against bug #151942, which seems related. I'm also going to reopen your original bug report, if you please could check if you're able to boot a hardy desktop installation cd.

I cam across this error when trying to run Ubuntu 8.0.4.4 server on VirtualBox (version 3.1.2). The solution was to enable PAE/NX (Settings -> System -> Processor -> Extended features checkbox).

Hope this helps.

Cheers ws
