Every SPICE channel is a TCP socket that is established after the initial handshake. IIRC, the first connection is kept for the graphics (which you can use) but the connection of others seemed to fail over your ssh tunnel. I'd guess the proxying over ssh tunnel needs more tweaks. I see that oVirt has some how-to with this, perhaps that can be helpful to you: https://ovirt-infra-docs.readthedocs.io/en/latest/Phoenix_Lab/Ssh_Spice_Tunnel/index.html > I started virt-manager on the client with the debug option > (--dubug) and attached the resulting output, containing a few > spice errors, to this email. > > In case you require more information please let me know. > > Thanks, > Thomas Cheers, Victor
