Rather, they provide increased parallelism which greatly improves processing power. <BR /><BR />System security is handled on a coarse-grained level by the VMM which ensures isolation between VMs, and on the fine-grained level by each OS which ensures isolation between processes running within a VM and the enforcement of user privilege levels.</DIV> <BR />Intel VT-x provides features related to VMM traps and privilege levels.
