[Qemu-devel] RFE- snapshot data storage location configurable

[dmc <dmc@filteredperception.org>]

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_.

thanks,
