Virtualization is the hottest ticket in the I.T. biz. But some society don’t understand that there are multiple ways to virtualize a computing environment.

Consider Microsoft’s Virtual PC for Mac, which provides what appears to be an Intel PC platform running on a PowerPC processor under OS X. that type of virtualization, called emulation, relies on emulating an entire hardware environment — processor and all devices — in software.

that works fine, but it has one significant problem — a huge performance overhead, considering emulating a processor in software takes a lot of processing potential.

An alternative to emulation is native virtualization, which formulates virtual machines on the core host processor, resulting in less overhead considering the processor can execute all directions at hardware speeds. that is the method used by Microsoft’s Virtual PC, which runs only on Intel processors under Windows.

The introduction of processors from Intel and AMD that include hardware

support for virtualization gives native virtualization a performance boost. Products that implement native virtualization and can use hardware assistance include VMware’s Workstation and Parallels’ Desktop. As whether that isn’t decent, other options include:

Paravirtualization, which is like native virtualization but requires guest operating systems to be modified (Xen, for example, now owned by Citrix Systems, and VMware ESX).

Operating system virtualization, which formulates virtual machines (also called virtual environments or virtual servers) from the host operating system (such as SWsoft’s Virtuozzo).

And application virtualization which encapsulates applications (for example, Microsoft Application Virtualization).

I bring all of that up to position the product I want to discuss: MojoPac from RingCube Technologies. Running with Windows XP only, MojoPac in effect provides a portable Windows XP desktop using operating system virtualization to create an isolated Windows XP guest virtual machine that runs alongside the host Windows XP.

The reason…
