# cat /etc/fedora-release ;uname -ri
Fedora release 19 (Schrödinger’s Cat)
3.11.1-200.fc19.x86_64 x86_64

Fedora 19 box has one NIC called p10p1.
p10p1 gets IP address over DHCP.
# cat /etc/sysconfig/network-scripts/ifcfg-p10p1

install open vswitch via yum
# yum install openvswitch

start open vswitch
[root@localhost ~]# systemctl enable openvswitch.service

configure open vswitch bridge
# ovs-vsctl add-br ovsbr0

associate ovsbr0 to phsical interface p10p1
Please note that you will lost internet connectivity after issuing following command.
# ovs-vsctl add-port ovsbr0 p10p1

after issuing following commands, you will get internet connectivity again.
[root@localhost ~]# ifconfig p10p1

start the VM
# virsh start f19-vm1

on the VM, confirm that the VM gets an IP address over DHCP.
