Hi all. Now that we're starting the process of integrating the PowerVM compute driver into nova[1], we're needing to change the namespace of the out-of-tree driver[2] so OOT consumers don't run into conflicts. You can track this change on gerrit[3]. The upshot: As you upgrade from newton to ocata, OOT nova-powervm consumers will have to change: compute_driver = powervm.driver.PowerVMDriver to: compute_driver = powervm_ext.driver.PowerVMDriver Feel free to contact us in IRC on #openstack-powervm if you have questions or concerns.
