Making the case for Hyper-V's superiority
Microsoft's Hyper-V will enter the virtualization ring as a relative underdog. But Hyper-V's price and better hardware compatibility poise it to compete with VMware and Xen.
By Anil Desai


Hyper-V no match for VMware ESX performance, features
Hyper-V may have certain advantages over VMware in terms of price, but in terms of management capabilities and functionality, VMware's capabilities far exceed its competition.
By David Davis


Lessening hypervisor importance may benefit Xen
From XenServer and to Sun xVM, Xen-based products have challenged VMware's market share and deemed hypervisor technology less relevant. Lower pricing, better packaging and less emphasis on hypervisors may spell long-term success for Xen.
