[virt-tools-list] [PATCH virt-viewer 2/2] app: Allow to connect to channel using unix socket

[Pavel Grunt]

Only method for connecting to channel opened later was ssh, however
this method failes when unix socket is used:

    <graphics type='spice'>
      <listen type='socket' socket='/tmp/spice.sock'/>
    </graphics>
