[libvirt] inability to open local read-only connection

[Tavares, John]

It is available via xm, so my point was if it can, why can't libvirt??

In the end, I had to switch to calling virsh until I can get all of problem resolved.

Ideally, virsh to would be able to provide most of the same data as going thru libvirt directly.  It might also be nice if it provided that data in a more machine parseable format.

We should be able to get the uptime of the guest's qemu process itself 
though, and report that back "over the wire" to a requesting client, 
without needing a guest OS agent.  Or even keep track of when libvirt 
launched the guest as wall clock time.

Not the same thing as "how long has the guest OS been up?", but 
potentially useful for management tools.
