[Spice-devel] lots of what looks like "memory issues" to me but I don't know enough to understand the messages...

OK, I created an Xorg.conf , by doing:


Xorg -configure

I edited the file and placed it in /etc/X11/xorg.conf. The edited 
section was:


Section "Device"
         ### Available Driver options are:-
         ### Values: <i>: integer, <f>: float, <bool>: "True"/"False",
         ### <string>: "String", <freq>: "<f> Hz/kHz/MHz",
         ### <percent>: "<f>%"
         ### [arg]: arg optional
         #Option     "EnableImageCache"       # [<bool>]
         #Option     "EnableFallbackCache"     # [<bool>]
         #Option     "EnableSurfaces"         # [<bool>]
         Option      "EnableSurfaces"            "False"   # On seems to 
cause lots of O-O-M issues
         #Option     "DebugRenderFallbacks"     # [<bool>]
         #Option     "NumHeads"               # <i>
         #Option     "SpiceDeferredFPS"       # <i>
     Identifier  "Card0"
     Driver      "qxl"
     BusID       "PCI:0:2:0"
EndSection

And indeed this seems to remove the errors from the log:

I guess my question is:

1: This was the default setup created by jessie "virtual-manager" ...it 
had no Xorg.conf (the norm nowadays)
2: The SPICE / VNC / QXL display  is limited to 65Mb
3: The QXL display driver (in the default setup) seems to use more than 65Mb


Just seems that some default is wrong here? If the limit of 65mb is set 
then why do the options use more than 65Mb
(I assume it's the QXL driver default?)
