Thanks for the suggestions, David!

<div><br></div><div>Potentially you could then look at concurrency by running sysbench on multiple guests to gauge degradation of performance due to concurrent I/O across nodes (if any exists), here I'd be particularly curious if high I/O on one compute node, due to replication caused a performance "hit" on another node.</div>

Each step is implemented as a separate shell script, which allows going slowly to understand every installation step. I thought it might be useful for some people; therefore, I'm announcing it in this mailing list.</div>
