 AN!Wiki :: Xen vs. KVM Benchmark - Nov. 2010

This is an attempt at an impartial performance comparison between the Xen and KVM hypervisors. All component specifications and software versions are up to date as of Nov. 09, 2010.

Specs

I use servers with the following specifications. They are not impressive, but they are consistent.

  • Specs - ASUS M4A785T-M/CSM
  • Specs - AMD Athlon II X4 600e Processor
  • Specs - Kingston KVR1333D3N9K2/4GB, 4GB (2x2GB) DDR3-1333, Non-ECC
  • Specs - Seagate ST9500420ASG

Platform Setup

All machines are relatively Red Hat Enterprise Linux version 6.0 x86_64 installations, updated as of November 15, 2010. Both machines, and the VMs inside them, were created using a very slightly modified version of the kickstart file below. Modifications are only to host names, user accounts, etc. Packages should be identical.

Post install, the packages below were installed.

 

Any questions, feedback, advice, complaints or meanderings are welcome.
