I disagree: the hardware virtualization mechanisms provide an extra level of protection. Just like the non-virtualized protection mechanisms do. No virtualization developer is under the impression that it's magical or bulletproof. You rely on the operating system's security mechanisms continuously, and developers work hard to fix bugs and vulnerabilities when they appear. Same goes for virtualization -- the security semantics are just different.
