   Cool, SPICE coming to guacamole!
   
   I just tried it out, using docker. It basically works, but I'm having trouble with the keyboard layout.
   I'm using a german QWERTZ keyboard, so I set the layout in the SPICE configuration also to German QWERTZ.
   In the linux VM I'm viewing via guacamole -> spice I also used "setxkbmap de nodeadkeys".
   
   When I type capital letters using shift, they work fine, but all other key combinations don't. So Shift + <any number> just types the number and not the symbol associated with it. Example: Shift+1 should type "!".
   
   Here is what xev shows on my laptop when I type Shift+1:
   
   ```

   And here is the xev output for Shift+1 from inside the guacamole spice vm:
   ```

   ```
   For some reason, a Shift_L release event is seen even if I didn't release the key.
   For the working capital letters, it looks like this:
   
   ```
   KeyPress event, serial 37, synthetic NO, window 0x4c00001,
       root 0x529, subw 0x0, time 1833793, (164,-12), root:(1035,420),

       XLookupString gives 1 bytes: (51) "Q"
       XFilterEvent returns: False
   ```
   Somehow a Caps_Lock gets involved there.
   
   There are other inconsistencies, if it would help to show them in detail, let me know.
