Osama,

Beyond that, KVM is excellent for desktop virtualization as well.  You
can use the "testdrive" utility in Ubuntu to easily fire up desktop or
server ISOs in a KVM virtual machine, without knowing much of anything
about KVM or virtualization.  You might also consider virt-manager,
for a wizard-based approach to creating VMs.

The only time I'd recommend you consider VirtualBox is if you need to
run virtual machines on a system who's CPU does not support VT
extensions.  In this case, VirtualBox will be about 10x faster than
KVM.
