For nova we're working on a devstack plugin that will add a repo config to the host and then upgrade a set of packages from that repo. The idea being to decouple the compile step from the job. basically: echo deb http://host/path main > /etc/apt/sources.list.d/bleeding_edge.list apt-get udpate apt-get install $package_list but you know with error handling etc. I'm sure it can be abstracted to handle multiple repos and package lists if you're interested? The devstack plugin could be taught to installed from a per-compiled tgz rather than a deb/rpm if you wanted but really packages aren't that hard. The challenge for you guys is the kernel side of things but if I understood correctly you can get the kenrel module from the ovs source tree and just compile it against the stock ubuntu kernel (assuming the kernel devel headers are available) is that right?
