I count it as an added security. A firewall running on the same hardware is not outside. There is no difference sp long the insulation is software-based. The only difference could be if the host OS is more secure than the guest one. Evidently, a guest OS is as secure as the host OS is, or less. > I think that VM-based sandbox is safer than no sandbox at all. I think that VM is yet another distraction (like firewalls, anti-virus software are) rather that a solution of safety problems of existing OSes and protocols. -- Regards, Dmitry A.
