There is a different side to that argument, according to Sjöstedt. He agreed that bare-metal hypervisors will make it easier to replace PCs. But that doesn't necessarily mean companies will be switching vendors all the time. It could also help organizations upgrade to PCs with the latest processors more easily than they can now, Sjöstedt said.
How PC vendors will see the issue remains to be seen. Both virtualization companies have Intel in their corner. VMware is in talks with the PC vendors, but hasn't got any deals in the bag that it can announce, according to Sjöstedt. Citrix is in the same position: some hardware vendors are interested, but that isn't anything the company can disclose publicly, a Citrix spokesman said via e-mail.
For the CIO, bare-metal hypervisors could let them entertain the idea of having users buy and bring their own PCs to work, according to Margevicius. A personal and a work operating system could run side by side, and be completely separated from each other.
The bare-metal hypervisor will definitely make the process of letting users buy their own PC or Mac much easier, according to Austin. One thing administrators could do that they can't with any other platform is to send out "a kill pill" from a central location when a user leaves the organization, he said.
VMware is seeing the same trend toward user-owned PCs, but has decided to approach it with a different product. It's accelerating development of a host-based virtual desktop solution for employee-owned PCs called View Manager Local Mode, according to Scott Davis, CTO for VMware's Desktop Business Unit.
Bare-metal hypervisors and employee-owned PCs are a bad fit because the IT department would have to bring in the computer, wipe it and then install the hypervisor, according to Davis. Bare-metal hypervisors are a better fit on devices that are owned by the company, and, for example, located at remote office or branch office locations.
"I have talked with a couple of oil refineries. They want managed end-points out on the rigs, where the network isn't robust enough for VDI and there is no IT personnel," said Davis.
VMware will ship View Manager Local Mode before Client Virtualization Platform. But VMware isn't saying when; "soon" is as far as Davis will go.
