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
Assuming all is fine, would it matter whether the VMs were F14 vs CentOS
I was thinking 3x runs each of;
- Recompile Michael's kernel
- ?? Please make suggestions
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
