[Bug 1737917] [NEW] Networking Option 2: Self-service networks in neutron
Public bug reported:
Hi all Cool Developer of Openstack,I followed the pike install doc and successful running openstack now,and In
Neutron configuration section,Verify operation Networking Option 2: Self-service networks(I choosed Self-Servrice network to deploy on Centos7x64 everything up to date)there we see:
The output should indicate four agents on the controller node and one agent on each compute node.
$ openstack network agent list
+--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+
| ID | Agent Type | Host | Availability Zone | Alive | State | Binary |

+--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+
and I run this command on controller node too after setup and configuration for openstack is over and then got this output:

seems running normally just like what we got in offical docs.and ip netns on controller:

and every virtual machine on openstack runs perfectly(self network or provider network,access to Internet),except one
day I log into compute node,and found the linuxbridge.log seems too big(over 300mb),quickly I use grep to filter out most INFO information and got so many ERROR log like this(also the only one type of error happens every fix period):

Here we see
"AgentNotFoundByTypeHost: Agent with agent_type=L3 agent a
nd host=compute1 could not be found\n"
So I come back to the compute node neutron configration section to check
if there was setup l3 agent on compute node I was missing,But checked
and found there never mentions that we need to install l3 agent on
compute node.
I googled these keywords and found only a little posts about this
problem,and most posts was about dhcp agent cannot found or old release
of openstack,so Is there a bug on neutron what should I do to avoid
this,should I install l3 agent on compute node or just ignore this error
info since all VMs runns as usual?

Here we see
"AgentNotFoundByTypeHost: Agent with agent_type=L3 agent a
nd host=compute1 could not be found\n"
So I come back to the compute node neutron configration section to
check if there was setup l3 agent on compute node I was missing,But
checked and found there never mentions that we need to install l3
agent on compute node.
I googled these keywords and found only a little posts about this
problem,and most posts was about dhcp agent cannot found or old
release of openstack,so Is there a bug on neutron what should I do to
avoid this,should I install l3 agent on compute node or just ignore
this error info since all VMs runns as usual?
