I have read a lot about running multiple slaves on a host machine that has the Jenkins master running on it, however, I am a bit confused on how to move forward. I want the Jenkins server to call slaves whenever it is possible in order to distribute the workload. In my case, each Jenkins slave will be building scripts from Unity3d projects. I have installed an Ubuntu VM on my mac where the master Jenkins server is and would like to know how to set it up.
Would I use another OS on the slave VM?
In addition, I am running the VM on VirtualBox, is this the best option or would another VM be better fit for this job?
Finally, if someone knows how to set this up, would it be possible for them to state how to set up a slave on the same machine as the server and connect both of them through ssh?
