This kernel requires the following features not present on the cpu : pae ...... Unable to boot - please use a kernel appropriate for your CPU.

[Dr. Who]

I am trying to set up Hadoop on my Windows XP "Hp Pavalion zt3000" that has pae.

1) I installed the most recent version of VirtualBox.

Then I set up the machine "JomoLInux", The memory, 353 MB and the virtual drive .... 12.5 Gb

2) The machine came up with no problem and I started it.

It said that it had no operating system.

3) Then I downloaded Ubunto 13.04 32 bit for desktop.

Then I set up a virtual drive in VirtualBox and assign the Ubunto iso to this drive and rebooted.

4) This is the error message that I received :

"This kernel requires the following features not present on the cpu : pae ...... Unable to boot - please use a kernel appropriate for your CPU."

5) I then powered down the VirtualBox and went to "Settings" -> "System" -> "Processor". And the Extended features _ Enable PAE/NX was geyed out by default. This means that it was turned "off" and I could not turn it on.

6) I then figured out how to turn on PAE via the API

VboxManage modifyvm Jomo-LInux -- pae on

7) I then went back to the UI in Vertual Manage and PAE was checked as "on". However there appers to be a minor problem - it was also greyed out.

8) When I rebooted my system and restarted VirtualBox, when it tried to install Ubunto I still received the same message. Even though it showed PAE as checked as "on" it was actually not turned on. I believe that this a bug in your software.

Sincerely Yours,

Jomo Willacy
