Title:
Open vSwitch Agent ID initalisation prevents reuse of agent with
userspace only vSwitches
Status in OpenStack Neutron (virtual network service):
Fix Released
Bug description:
Problem description
===================
In the Open vSwitch agent, the Agent id is currently based off the mac
address of the br-int.
Userspace Open vSwitch derivatives such as the Intel® DPDK Accelerated Open
vSwitch do not currently create a tap device in the kernel to back the ovs
bridges local port.
This limitation prevents reuse of the OpenVSwitch agent between both switches.
By allowing integration of high throughput vSwitch implementations via
existing agents, NFV workloads can be enabled in OpenStack without significant
extension of the current codebase.
Proposed change
===============
To enable reuse of the ovs agent with the Intel® DPDK Accelerated Open
vSwitch the proposal is to change the generation of the agent_id to use the
hostname instead of the mac address of the br-int.
- mac = self.int_br.get_local_port_mac()
- self.agent_id = '%s%s' % ('ovs', (mac.replace(":", "")))
+ self.agent_id = 'ovs-agent-%s' % socket.gethostname()
For several plugins such as the nec,mlnx,hyperv and onconvergence agents the
hostname is used to create the agent id.
Using the hostname will normalise the agent_id between these 5 neutron agents.
at present the Agent_id is only used in log messages. by using the
hostname instead of mac of br-int log readability will also be
improved as it will be easier to identify which node the log is from
if log aggregation is preformed across a cluster.
Patch
