* Maximizes availability by segmenting critical processes running on one guest operating system from less essential processes running on another guest operating system or mirror applications on different operating systems for redundancy.
The final approach Solling proposes is the concept of deploying the IPS security feature as a client on the guest operating system, though he doesn't recommend it above the other two, which help AG's solutions typically fall under.
With this feature, PCI hardware directly connected to the computer could be made directly available to the guest operating system. While this is not supported currently, but such a feature could eventually allow one to dedicate a graphics card to one of the running virtual machines, thus allowing it to use hardware acceleration directly, and make it feasible to run 3D applications or even games in a guest VM.
Windows Server 2008 R2 Enterprise ships with four guest operating system licenses to offer costs savings, the company said.
The hypervisor--the part of the virtualization framework with which virtualized guest operating systems interact--creates software facsimiles of the underlying hardware, and the virtualized guest operating system interacts with the virtual hardware.

Multiple Padded Cell applications can run concurrently on a single physical computer, each hosting its own guest operating system. An impenetrable wall around each virtual computer ensures that errant, insecure or malicious code can never compromise the security or reliability of the rest of the system--either inadvertently or via a hostile attack.
