Our performance comparisonof XenSource XenEnterprise 3.2 beta to VMware ESX Server 3.0.1 is now available, having been vetted and approved by VMware’s benchmark police.

As hinted at earlier, we have nothing to be ashamed of, and lots to be proud of, given the fact that XenEnterprise hasn’t reached its first birthday yet. In most tests, the results for the two virtualization platforms are essentially indistinguishable; in the Linux test, the value of paravirtualization is borne out strongly.

Thanks to our competitors across Palo Alto for their speed in reviewing and approving the results and paper. While we still find the process to be one-sided and ultimately unfriendly to the marketplace, given the limitations, they came through.
