I guess a VM using a single core and 512 MB or 1GB RAM would be a reasonable starting point. A Rpi-2 would be great as well. You could just test from the latest master branch, and it *should* work. Currently, a role called 'Pathagar' is broken, so you may have to disable installing it in vars/default_vars.yml when you give it a go.
Is using a VM, I often tend to use vagrant. You can use a fedora 21/22 minimal or centos minimal image. This is the image I used for testing my XSCE install, where things went smoothly - https://github.com/holms/vagrant-centos7-box/releases/download/7.1.1503.001/CentOS-7.1.1503-x86_64-netboot.box If using centOS you will need to enable the epel repo - *yum install epel-release* Hope this helps.
