+-----------
+
+Show SPICE server information.
+
+Return a json-object with server information. Connected clients are returned
+as a json-array of json-objects.
+
+The main json-object contains the following:
+
+- "enabled": true or false (json-bool)
+- "host": server's IP address (json-string)
+- "port": server's port number (json-int, optional)
+- "tls-port": server's port number (json-int, optional)
+- "auth": authentication method (json-string)
+         - Possible values: "none", "spice"
+- "channels": a json-array of all active channels clients
+
+Channels are described by a json-object, each one contain the following:
+
+- "host": client's IP address (json-string)
+- "family": address family (json-string)
+         - Possible values: "ipv4", "ipv6", "unix", "unknown"
+- "port": client's port number (json-string)
+- "connection-id": spice connection id.  All channels with the same id
+                   belong to the same spice session (json-int)
+- "channel-type": channel type.  "1" is the main control channel, filter for
+                  this one if you want track spice sessions only (json-int)
+- "channel-id": channel id.  Usually "0", might be different needed when
+                multiple channels of the same type exist, such as multiple
+                display channels in a multihead setup (json-int)
+- "tls": whevener the channel is encrypted (json-bool)
+
+Example:
+
+-> { "execute": "query-spice" }
+<- {
+      "return": {
+         "enabled": true,
