I just get my private beta trial for HPcloud to be test. As u all know its base on Openstack but then i plan to try out its CLI method to manage the instances . Documentation about HPcloud CLI can get it here . The issue here is the cli (base on ruby) require ruby 1.9.2 and above but in precise pangolin default ruby is 1.8.7. I already file a bug report on this issues. I hope someone can work out or decide that ruby1.9.x will be default in precise.
