8.10 Server Edition not working in VirtualBox

[M4rotku]

Hey all,

I tried to install 8.10 Server Edition on a virtual machine to play around with it to see if I would be capable of creating a file sharing server. After installing, upon booting from the hard drive, I received the following error:

Boot from (hd0,0) ext3 5ee5ac25-c281-4b04-9fef-12e233ce5ec9
Starting up ...
This kernel requires the following features not present on the CPU:
pae
Unable to boot - please use a kernel appropriate for your CPU.

I realize that this is probably a noobish error, one that would normally go in a beginners section, but I couldn't find a specific beginners area for the server edition. Any help would be appreciated.

Much thanks,
M4rotku

There is a setting in Virtualbox you need change.

1. Close down your boot failed VM
2. Select that VM in the list in the VirtualBox GUI
3. Click on the Settings button (top menu)
4. In "General" select the Advanced tab
5. look at the settings and about half way down you will see:

A tick box with "PAE/NX" next to it

6. Put a cross in the box
7. Try booting now

You can also do this from the command line:

To tick the box:
VBoxManage modifyvm "Ubuntu Server" -pae on

To untick the box:
VBoxManage modifyvm "Ubuntu Server" -pae off

Thanks you, it worked.

I was assuming that it was missing an application by that name. Such an easy solution for a confusing problem.

TYVM.
