Nearly two years after VMware announced its "vClient" initiative to give customers a range of server-hosted and client-hosted virtual desktop options, VMware has failed to deliver one of the initiative's key technologies.

While VMware offers server-hosted desktops with VMware View, its virtual desk infrastructure (VDI) product, the company announced in September 2008 that it would also deliver "Client Virtualization," also known as a bare-metal desktop hypervisor.
Client hypervisors allow desktops to run in a virtual machine installed directly on a user's laptop, rather than in a server inside the data center. The approach allows centralized management of desktops, while potentially giving users better performance than VDI technologies that require applications to run on remote servers.
Client hypervisors may enable "bring-your-own-PC-to-work" scenarios by letting user machines host one desktop for personal applications and a separate desktop environment for work applications.
By January 2009, rival Citrix announced that it was working on its own client hypervisor. At the time, a VMware spokesperson projected that VMware's client virtualization, still in development, would be released in the second half of 2009.Both Citrix and VMware struggled to deliver client hypervisors within their self-imposed timelines, but Citrix beat VMware to the market in May of this year with XenClient.
VMware's bare-metal desktop hypervisor is still under wraps, and no release date is being specified.
"It's not an easy computer science problem to solve," acknowledges Bogomil Balkansky, VMware's vice president of product marketing.
Gartner has speculated that developing all the necessary drivers needed by PC users is a challenge, as is persuading PC vendors to ship and support client-side hypervisors.
When asked if VMware will deliver the client hypervisor in 2010, Balkansky says "we don't have a timeline."
Balkansky seems to indicate that development of PCoIP, VMware's protocol for allowing remote access to workstations and servers from thin clients, is taking precedence over work on the bare-metal hypervisor.
"On the desktop side, we've been focusing our attention on the user experience with the PCoIP protocol," he says.
