[Qemu-devel] Write cache enable from guest at runtime

[Stefan Hajnoczi]

Hi Christoph,
I have written up thoughts on write cache enable, including a
workaround to change O_SYNC on a file without kernel changes:

http://wiki.qemu.org/Features/WriteCacheEnable

Guest ability to control write cache enable is useful and I'd like to
see it in QEMU soon.  Any thoughts about what I've posted?  Care to
submit your patches?

Stefan
