Virtual Computer Virtual Computer, based in Westford, Mass., calls its client-side hypervisor Distributed Desktop Virtualization. To learn more, read the related review."We're working on a deal now with Lenovo that will have our hypervisor running on a whole different class of machine, everything from laptops down to desktops," CEO Dan McCall told eWEEK. "Lenovo is seeing a convergence between the thin client and the desktop PC. Taking laptops aside-because that's a different segment of the market [since they are not "tethered" machines]-there's actual overlap between the high end of the thin-client line and the low end of the desktop line, with the low end of desktops probably getting more performance than thin clients."Both those segments, however, can now run client-side virtualization, McCall said, indicating that previous laptop generations didn't have the horsepower to run a local client plus the virtualization agent at the same time. Virtual Computer gives users some choices within deployments, which could include a mix of desktops, laptops and other mobile devices. For example, McCall said, a NxTop-powered laptop could be running Windows 7 locally on the client while at the same time providing a separate window into a server-based deployment of something else, such as Linux or another Windows version. "We try not to get too religious about how you want to run virtualization," McCall said. "We allow you to lay down our product, NxTop, at the base layer for all these devices-which are all essentially personal computers. Then you make the choice about whether you want to run your workload in the data center on VMware ESX or a Citrix XenServer environment, or run your virtual machine locally. "That's really the innovation we're providing to this market right now," he said. VC's NxTop (pronounced Nextop) 3.1 RC1 will become available for download April 19.
