Reverting to 0.8.8 for libvirtd - and virt-manager 0.8.6 - works connecting to the 0.8.3 systems. Dropping to 0.9.2 didn't. Is this by design that, say, 0.9.x isn't backwards-compatible in terms of using virt-manager on it to manage 0.8.x systems? Or is it a bug I should file somewhere? Thanks, Whit
