> What's the utility of being able to disable virtualization ?
I consider the option to disable (or rather: enable this function manually if you need it) virtualization to be quite useful because if this feature is disabled, malicious software cannot install a virtualization rootkit, i.e. a rootkit that makes itself a hypervisor and moves the current OS instance into a virtual machine running under this hypervisor.
