Our recent tech report on performance evaluation of Xen vs. OpenVZ is generating quite a buzz. It’s the second most viewed tech report from outside HP. Virutal strategy magazine picked up on it and wrote an article. A few people including Simon Cosby, CTO of Xensource responded. Slashdot picked it up yesterday. I am pleasantly surprised that there is not much FUD generated by the Slashdot readers in the comments. Some of the comments are quite informative. Virtualization.info and OpenVZ blogs have written about it too.
Let me point out a few facts straight away. Both technologies have their place. Xen trades off performance for security and isolation and if you want to run multiple operating systems Xen or VMware is the only way. OS level container technologies like OpenVZ beat these hypervisor-based technologies easily on performance, but they may not be appropriate for some situations.
