Installing Ubuntu 8.04 server on VirtualBox
June 11, 2008 23 Comments
If you are getting the following error on installing Ubuntu 8.04 server on VirtualBox:
The kernel requires the following features not present on the CPU 0:6 Unable to boot - please use a kernel appropriate for your CPU
Then, you need to enable the PAE support for the virtual machine.
Follow the screens:
1. Open the settings for the machine (Ctrl + S).
2. Check the Enable PAE/NX bit.
Hi, I tried this but had to realize that I don’t have such a button.
I only have the 3 Button ACPI/IOAPIC/VT.
Is it possible that this is a new feature only available in newer Versions? I’m still on 1.5.6
Yes, I was right in my previous post – PAE is obviously available from 1.6.0 – see http://forums.virtualbox.org/viewtopic.php?t=6101
Again – the thing that also helps is hinted here at tombuntu: http://tombuntu.com/index.php/2007/09/05/making-ubuntu-server-work-in-virtualbox/
Henning I tried the method listed above but it didn’t suited me for the following reasons:
1. First I have to download that bulky kernel and install it, its both bandwidth and time consuming.
2. By installing older kernel you are degrading urself (unless it’s the only option left i wudn’t recommed it)
3. There was an easier option available.
But still thanks for pointing out the link at-least it’s good that an alternative exists.
Thanks for this info! I found this blog entry with google and it was just what I needed to have my test server running.

Works great. Thanks for taking the time to post this.
Thanks a bunch, that works a treat! What is PAE and why is it needed after installing the guest additions?
Your tip worked 100% for me.
I’m running a ubuntu server 8.04 LTS over a Win xp.
Thank you very much for this tip!
