[libvirt] [PATCH 09/18] conf: Add <filesystem model='virtio-{non-}transitional'/>

<filesystem> devices lack the model= attribute which is used by most other device types. To eventually support virtio-9p-pci-{non-}traditional in qemu, let's add a standard model= attribute. This just adds the domain_conf wiring Signed-off-by: Cole Robinson <crobinso(a)redhat.com&gt; --- docs/formatdomain.html.in | 4 +++ docs/schemas/domaincommon.rng | 9 ++++++ src/conf/domain_conf.c | 32
