John,

For some, IT and ITs Virtualisation may be as a Playground in which all who battle or engage in battles will lose, and a possible response ....."Last month Microsoft fixed in MS07-049 a thread they classified as important that allowed a break out of the virtual OS to the host OS. We had some disagreement on that rating with Microsoft as we saw it as a significant bigger deal than "just" privilege escalation." .... http://isc.sans.org/diary.html?storyid=3411 .... is not a solution. There may be no solution but only a series of responses which will ever increasing have the Host OS following Virtual Instruction Sets. However that would be a Stronger OS with fewer, if any Conflicts. It would certainly be Virtualisation's AIM...... Streamlined Mainstreaming of Shared Source.

And I think I would definitely agree that such a thing is a significant bigger deal, for it is Raw Pure Stealth?

M$ is insisting that Virtualization vendors implement the Enlightenment "shim layer", to allow the guest image to be aware of and in formal contact with the hypervisor. This will allow a direct path for hacking by breaching the firewall between the guest and the host environment, and probably allow for some interesting DRM and EULA enforcement as well.
