remote-viewer silently exits if qemu spice/vnc server closes connection.
This seriously confuses users. As they do not know the what have happened.
It would be fine a have pop-up message with a message something like:
"You were disconnected from virtual machine."
+ A reason (optionally): lost connection, qemu crashed, etc...
+ Button: OK
If the server crashes than it probably cannot send a message to the client with the reason of dropping the connection.
Disconnecting by another client - it is easy to prevent by setting a password
Disconnecting because the shutdown - I believe a pop up saying "You have turned off your VM" is not very useful
Maybe I miss some useful usecase - feel free to reopen with it.
