This might be a feature request. It would be awesomely nice to have the kernel module (kmod-openvswitch) for Fedora. Userspace installation is not that cool. Please, could you include it?
ping?
The kernel module 'openvswitch' is available in Fedora 17 /lib/modules/3.5.2-1.fc17.x86_64/kernel/net/openvswitch/openvswitch.ko
