1. If failures occur in connections that are using ssh,
   you must ensure that in the system installed ssh
   and an application like ssh-askpass for your DE,
   also the environment variable SSH_ASKPASS was set.
   For example: SSH_ASKPASS=/usr/bin/ksshaskpass
   You can do it in $HOME/.bash_profile file at least.

2. Adding devices implemented partially.

3. In Spice client viewer:

    * the Smartcard manager is not implemented yet.
