Re: Very poor performance on KVM with Ubuntu 12.10 guest

Hi

The file doesn't exist on the host and I had already written off Ubuntu 12.x, the host is command line only, I moved to Xubuntu, which offers better performance, I am hoping I can improve it by using the guest source provided by spice, the Ubuntu guest was partially crashing (launcher I think). 

I've not decided whether to stick with Xubuntu yet.

I also have a problem with en-gb map not mapping some keys despite being configured in spice and on the guest os (#~ not working at all, @' mapping to ¬` and ¬` not working at all)

It is only a problem through spice, but three (four when programming) of these are quite important.

It's not the US map as " would be @, so I am about to Google for it, to see how I can edit it, and which bit is the problem

In addition to what Christophe writes, you can try to disable surfaces
in the guest driver:

# cat /etc/X11/xorg.conf.d/qxl.conf
Section "Device"
         Identifier  "qxl"
         Driver      "qxl"
         #Option  "DPI"   "96 x 96"
         #Option "ENABLE_IMAGE_CACHE" "True"
         #Option "ENABLE_FALLBACK_CACHE" "False"
         Option "ENABLE_SURFACES" "False"
EndSection

they are known pain point in linux guests.
