Comment 6 for bug 966849

Well, this particular feature is enabled and working as-is with the binary provided by qemu-kvm. Currently, we have situation where you can have a libvirt based VM that works with <filesystem .../> definition and <devices><emulator>/usr/bin/kvm</emulator>...</devices> but fails if this is changed to /usr/bin/kvm-spice, which enables other goodies related to SPICE. For this reason I wouldn't be too concerned about the possible 9p related issues.. qemu-kvm-spice is already more "unstable" than qemu-kvm but currently it doesn't support all the features the "stable parent" does...
