They switched the default cache to writeback in qemu 1.2 which is

F17 shipped with qemu version 1.0.1 which I think defaults to writethrough.
If you don't change the command I'd think you should get writeback automatically
after the upgrade.
Indeed, I would suggest to go with QEmu defaults there and not try to
override. I/O and consistency there are very complex issues, I would say
don't try to change the default unless you really know the issues at
hand and the specifics of the target system :-)
