Thank you for your interest in this project and Xen!

Firstly, I would recommend to install Xen from source on your test
machine. If you don't have a test machine, you could install it on your
laptop. Alternatively, Xen on ARM works well on the Cubietruck, also
known as Cubieboard 2 [1][2]. Finally, Xen works also well on top of Xen
or KVM virtual machines on x86 (nested virtualization), so that would be
another way to test it.

I fully agree that the best way to get started is by submitting small
patches.  We'll get back to you soon with some examples of potential
small fixes to do. In the meantime, I encourage you to setup a dev and
test environment.
