if ret is None:raise libvirtError('virConnectOpen() failed')
libvirt.libvirtError: virConnectOpen() failed

This is what it looks like when there is no local running hypervisor. This particular traceback needs to be caught earlier in the application (aka test for Xen if trying to build Xen images locally) but is a good example of what we need to catch and gracefully handle.
