For provisioning I have a beaker plug= in, other plugins can be added if needed. Even without beaker one can also = provide an installed machine and skip the provisioning step. Runperf would = then only apply the profiles (including fetching the VM images from public = sources) and run the tests on them.

As for others they can eithe= r use beaker plugin as well or they can just prepare the machine prior to t= he execution as described in the previous paragraph. FWIW I'm not aware of anyone else taking on this work upstream. Whatever you can do for upstream will be the QEMU disk/network/etc preformance regression testing effort. Someone might show up with engineering time and machine resources, but the chance is low.
