AFAIK there are some issues with that benchmark not being free.
What I'm basically looking for is a simple comparison of a few key metrics between common setups. For example a simple bonnie++ run on XenPV and KVM+virtio_blk could already give people at least some baseline numbers.

I'd be happy to run some benchmarks. I've got some identical (if humble) machines... Would you want just a Xen vs. KVM? If so, what parameters or setup options would provide the best apples to apples comparison?
The machines are;
- quad core athlon II x4
- 4gb ddr3
- 1x 7200rom 500GB drive
- Fedora 14, stripped (but identical) installs
If these are too low end for useful results, let me know. Otherwise, I'll fire up Xen under Michael's 2.6.32-25-172 kernel with the stock 4.0.1 hypervisor on one machine, and can use the stock KVM/QEMU setup for another.
Assuming all is fine, would it matter whether the VMs were F14 vs CentOS 5.5?
I was thinking 3x runs each of;
- bonnie++
- Recompile Michael's kernel
- ?? Please make suggestions
Digimer,
I would think the latest xen vs the latest kvm would be best. Fully virtualized vs Para-virtualized, is that possible with kvm? I don't believe your specs are too low end, they actually match pretty close to what I have and I don't think the OS matters that much as long as they are identical setups.
Thanks for offering to do the comparison, I am very interested in your results.
