For those that are unfamiliar with the project, PyPy is an implementation of the Python language that features a JIT Compiler. I have noticed a huge performance benefit in some personal projects by switching to PyPy. I have always been curious how it would perform on a large and complex project like OpenStack, but my early experiments ran into massive roadblocks around broken dependencies.
It has been six months since I last looked, so I figured it was time to try it again. Support has come a long way and, now that lxml is working, we are close enough to get a Proof-of-Concept running. Read on for instructions on running nova with PyPy.
Start out with a base ubuntu 12.04 (precise) install and run devstack. I won't go through the details of getting devstack running here, because there are already instructions on the devstack site.
