KC, The reasoning is that the internal handling of VLANs changed in version 1.9.0 and our libvirt implementation only supports the “new” way of configuring VLANs. At the time when i wrote the ovs integration for KVM version 1.9 of OVS was already released for quite some time and we are using some of the features it provides, hence the version dependency.
In general it is very unfortunate that some distributions keep on delivering a very old and buggy version of OVS. For any type of production system i would really advice to use a recent version of OVS.
