Back around fedora 16 I tried all the different virtio cache modes and experimentally discovered that cache=none was nearly infinitely faster than cache=default and cache=writeback was even a little faster than cache=none. So I set all my VMs to cache=writeback.
I've been copying my virtual machine defs to each new fedora since then, but now it seems to be dog slow with disk IO again. I'm planning to experiment with different settings again, but I have to wait for my Windows XP virtual machine to finish doing a windows update which may take all night at the rate it is writing to disk :-(. Just thought I'd ask if there is some known difference in the virtio modes in fedora 18? _______________________________________________ virt mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/virt
