I'd like to be able to set the disk caching properties in the web gui. The caching properties are:

-writeback: highest performance, high risk of data corruption on power failure.
-writethough: uses host paging file, has perfomance problems with qcow2.
-none: no host caching.
-default: writeback for qcow2, writethrough for all others.

With the qcow2 format either writeback or none supposedly performance better than writehrough.

Would these settings be a good candidate for addition to the gui? Is there a way I can play with these from the shell?
