Another of Dike's projects is to implement UML over KVM, which will bring further speed advantages but "I need to make UML run under KVM first."

When a question from the audience asked what needs to be done in the Linux space to manage virtualization. Dike said there needs to be a common way of managing heterogeneous virtualized environments and "people are thinking about that."

One solution to the management challenge is libvirt, an API that allows software to interact with the virtualization capabilities of Linux.

Another comment from the audience was that the management aspect is "a much bigger problem than the kernel level stuff."

"The big companies look for chances to write big bloatware [but] don't expect management to be complete before the virtualization wars," he said.
