The Euclyptus implementation on Ubuntu Enterprise Cloud requires KVM.
To check if your hardware supports KVM, run the command "kvm-ok" or
follow these steps (from ):

If your hardware does not support KVM, has the error you have indicated
seem to show, you will can:
1/ Use some other hardware that supports Intel VT or AMD-V (this is more
and more common now days).
2/ turn to an implementation of Eucalyptus which is based on Xen,
meaning not an Ubuntu implementation as Ubuntu does not support Xen as a
virtualisation layer (only as a guest). Please see the Eucalyptus site
 for more info.
