After a bit more hacking through the code I think this has to do with PolicyKit authentication. The server is currently enabled to do PolicyKit based authentication. And policy kit is disabled or can't be found when building on RHEL4/5 Question: 1. Is Policy Kit available on RHEL4/5 and can the libvirt client be policy kit enabled on the client? 2. Without PolicyKit enabled on the client and server side, is it possible for a non-root user to have Read/Write "qemu:///system" remote access to the server?
