This works well except I notice that if the host makes new changes the guest does not see it. This just means the guest has to reboot every time before running 'make modules_install install -j 8' and it is unexpected and not user friendly. I wanted to see if someone was working on fixing this yet. I've tested with both cache=loose and cache=fscache. We use msize 131072, no security and virtio-9p-pci.
