Log-off SPICE client system from oVirt guest
Hello everyone! I currently have an MS Windows client running remote viewer which connects to an oVirt Linux VM using SPICE. My applicaiton is running on the VM. (Actually there are several clients each connecting to one VM at a time, with each client connecting to the first available VM every time - I have already achieved this using the oVirt REST API). What I want to do now, is have the MS Windows client (I am using remote-viewer as the SPICE client) log out automatically when the user closes the application's window in the VM. Is this possible? If not, is there a way to get the IP address of the client machine (the one running remote-viewer) from the guest so that I can notify it to log off? Best regards, George.

do I understand correctly that you wish to log out a user at Client machine (the one where actual user physically sits at) when an app in the guest machine closes? If so, I'm afraid that oVirt won't have anything like it integrated in foreseeable future so you'll have to come up with something yourself
If not, is there a way to get the IP address of the client machine (the one running remote-viewer) from the guest so that I can notify it to log off?
IMO the other way is easier: 1) run remote-viewer through a wrapper that will log off the user if told to do so. Wrapper can get the guest IP address from API (GET /api/vms/VM_UUID -> <vm><guest_info><ips><ip address="GUEST_IP">) 2) create a service in a guest that will emit the signal to log off to the connected client when the app in question exits. maybe you could use a new "port" channel of spice but IIRC that would require modification of a client...

Thanks David! I think I am gonna go for a combination of the two approaches: have the client retrieve the IP of the guest and connect to a service running on the guest and once the application running inside the guest closes, notify the client to close the SPICE connection and log off the user.
