Finally got some time. It says "Connection:" is "qemu:///system", and gives the LAN-local hostname. I tried:If you look at the connection details in virt-manager, it should tell you the full URI it used - use exactly the same URI with virt-viewer.I tried to find connection details in virt-manager, could not. Where is this to be found?In the main virt-manager screen, highlight your connection and use the menu bar Edit -> Connection Details. On the 'Overview' tab in the dialog that pops up the first line shows 'Connection: [YOUR URI]' Daniel
and then within a ssh +X IP session
All of them failed the same way, with a popup reading "Cannot find guest domain...".
