 OOM. Not releasing?
  Out of memory allocating 3145748 bytes
  Out of mem - stats

 Cursor channel missing.
 No copy paste.
 No agent at all.
  agent should probably be thought to run with Xspice too. That way
   mouse emulation in Xspice can be avoided entirely. But how do you
   get an input device to belong to Xspice :1.0 and not to Xorg :0.0?

 Keyboard:
  * repeat (xset r 100) does nothing. This is because spice client
   of course does repeat. But would be nice to transmit this.
 
 Video: youtube seemed choppy, some frames were repeating (cpu 30%~, so not
  cpu bound). Possible multimedia time? Isn't this set by the driver, i.e.
  should be identical with in vm qxl driver?

 Performance:
  didn't check.
