Please explain. What is this 'disk cache mode' you speak of?
part of the virutal machinery or my base installed OS?
In virt-manager when you look at the VM properties (the light bulb
icon), you can select different bits of virtual hardware and
fiddle with things like the disk cache mode.
Annoyingly, however, all it ever says when you look at it
at first is "default", so you have no clue what the default
setting is. I experimented once a long time ago with all the
different cache modes, and found writeback much faster than
the default (or course, for all I know the default is now
better, but I can't tell because I still can't find out
what "default" means :-).
