VMware is ahead of all of us. But XenSource has unique gearing ratios to catch up. Xen is a community product so we get the benefit of that development ability, a rate of feature set development.
VMware will tell you we are behind them in terms of the infrastructure around VMware. Our architecture and approach are different. VMware wants to buy, own, or build anything around virtualization, from backup to HA [high availability]. XenSource has a rich, open approach to the eco-system, and we work with the best vendors in every category.

Microsoft's forthcoming hypervisor, code-named Viridian, will include components from XenSource, making you partners and competitors. What's that relationship like?
If Microsoft will have a hope of being the platform of choice for virtualization, they will have to deal with different guest types. We deliver the enablements to let Linux to run as a first-class enlightened guest OS on top of the Viridian hypervisor. It will only be credible if it can virtualize things other than Windows.
