Looks like my real problem may be not incorporating a Debian/Ubuntu patch before building 0.9.x, since netcat differs:

Hmm, what was the error message you were getting? We've made efforts at the libvirt level to have useful error reporting here, so that the cause of failure is more obvious. Also, I patched virt-manager a while ago to use a shell script to handle both RH and debian 'nc' versions. Script is here: http://git.fedorahosted.org/git?p=virt-manager.git;a=blob;f=src/virtManager/... Yeah, it's complete and utter crack, but this has been a constant frustration for users, so maybe worth revisiting at the libvirt level (and hey, launching nc over ssh is kinda crack to being with :) ). Even if we solved this in a clean way by providing our own /usr/libexec/libvirt_nc binary, we'd still probably have to play shell script games over SSH to handle connecting to older libvirt (or what if libvirt_nc was installed somewhere other than libexec?) - Cole

That's in the 0.9.0 virt-manager, but fails in my context, which where the systems I'm trying to manage are 0.8.3 from Ubuntu debs, and I'm on the latest versions of this all built from tar. Whit
The error from virt-manager 0.9.0's perspective is: Unable to open a connection to the libvirt management daemon.
