I have a pretty ugly patch against qemu 0.8 which allows the location of data
used with the -snapshot feature to be somewhere other than /var/tmp. I have a
use-case where I am creating many gigabytes of changes to disk in snapshot mode.
When 0.9 came out, I looked, but it seemed less than trivial to update my
patch, which was a pretty ugly hack to begin with.
I don't suppose anybody else thinks this would be a useful feature? Or at least
someone who can rattle off the top of their heads the sorts of things I should
keep in mind while trying to put it together myself?
A further extension, which I would like, but is also more complex to add, would
be the ability to specify -snapshot, _per device_.
I also thought that would be useful earlier but now qcow2 overlays
provide much better flexibility and don't litter the commandline
syntax. I think the currently available choice between -snapshot (for
the simplest possible use case) and qcow2 overlays (for anything more
complex) is a perfect balance for usability and there's no need to add
more switches.
