# -- Notes for updating from Icehouce
|
|
|
|
OVS.bridge_mappings is deprecated for ofagent. It was removed in Kilo.
|
|
Please use AGENT.physical_interface_mappings instead.
|
|
To mimic an existing setup with bridge_mapping, you can create
|
|
a veth pair, link one side of it to the bridge, and then specify
|
|
the other side in physical_interface_mappings.
|
|
For example, if you have the following:
|
|
|
|
[OVS]
|
|
bridge_mappings=public:br-ex
|
|
|
|
You can do:
|
|
|
|
# ip link add int-public type veth peer name phy-public
|
|
# ip link set int-public up
|
|
# ip link set phy-public up
|
|
# ovs-vsctl add-port br-ex phy-public
|
|
|
|
and then replace the bridge_mappings with:
|
|
|
|
[AGENT]
|
|
physical_interface_mappings=public:int-public
|
|
|
|
After Icehouce, most of the functionality have been folded into
|
|
a single bridge, the integration bridge. (aka. br-int)
|
|
The integration bridge is the only bridge which would have an
|
|
OpenFlow connection to the embedded controller in ofagent now.
|
|
|
|
- ofagent no longer uses a separate bridge for tunneling.
|
|
Please remove br-tun if you have one.
|
|
|
|
# ovs-vsctl del-br br-tun
|
|
|
|
- ofagent no longer acts as an OpenFlow controller for physical bridges.
|
|
Please remove set-controller configuration from your physical bridges.
|
|
|
|
# ovs-vsctl del-controller ${PHYSICAL_BRIDGE}
|
|
|
|
The support of ancillary bridges has been removed after Icehouce.
|
|
While you can still use these bridges to provide connectivity,
|
|
neutron-ofagent-agent no longer reports port state changes (up/down)
|
|
for these bridges. If it is a problem for you, please consider
|
|
tweaking your configuration to avoid using ancillary bridges.
|
|
We recommend to use a provider network instead as the following:
|
|
|
|
- Make l3-agent external_network_bridge configuration empty.
|
|
eg.
|
|
[DEFAULT]
|
|
external_network_bridge=
|
|
|
|
- (Re-)create a network (and subnet) for public connectivity with
|
|
a flat provider network.
|
|
eg.
|
|
neutron net-create $PUBLIC_NETWORK -- \
|
|
--router:external=True \
|
|
--provider:network_type:flat \
|
|
--provider:physical_network=$PUBLIC_PHYSICAL_NETWORK
|
|
|
|
- Associate your neutron router to the above network.
|
|
eg.
|
|
neutron router-gateway-clear $ROUTER_ID
|
|
neutron router-gateway-set $ROUTER_ID $PUBLIC_NETWORK
|
|
|
|
- Add the corresponding entry to bridge_mappings.
|
|
eg.
|
|
[OVS]
|
|
bridge_mappings=$PUBLIC_PHYSICAL_NETWORK:$PUBLIC_BRIDGE
|
|
|
|
The port naming scheme for ofagent has been changed after Icehouce.
|
|
If you are using security groups, you should switch firewall_driver
|
|
accordingly.
|
|
From:
|
|
[securitygroup]
|
|
firewall_driver=neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
|
|
To:
|
|
[securitygroup]
|
|
firewall_driver=neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
