According to official docs ( (, when using ovs-agent there should also be linuxbridge used for security groups.

Linux bridges handling security groups. Due to limitations with Open vSwitch and iptables, the Networking service uses a Linux bridge to manage security groups for instances.

In my enviroment, I use ovs-agent + ml2 to setup vlan tenant networks and flat provider networks. But when I create vm on tenant network there is no linuxbridge on my compute node. I do not know if it is normal. Should I startup the linuxbridge agent service?
