Ubuntu Server Error Message on Virtualbox
"This kernel requires the following features not present on the CPU: 0:6 Unable to boot - please use a kernel appropriate for your CPU."
downloaded ubuntu server 8.0.4.2
mount the iso instead of cd rom drive
create at one go a 4GB hd (all text based, does not need a lot of space)
run the ubuntu setup-> manual partitions: 2GB for ubuntu, 500MB for swap
NOTE: right control key to "take control of mouse" to host...
computer name: ubuntu, user: username
e.g. a LAMP server as a development environment openSSH server I can use putty/ssh (once networking is setup) no DNS because any future virtual cpu's will be static ip's
finished but received stupid error message:
"This kernel requires the following features not present on the CPU: 0:6 Unable to boot - please use a kernel appropriate for your CPU."
THE SOLUTION
Shutdown the VM. Open the settings on the VM through the Sun xVM VirtualBox manager General -> Advanced -> check Enable PAE/NX Start your VM
