Comment 11 for bug 1443607

Hi Darragh,

I'm using Kilo and did not see any traceback with your patch.

I'm using a multi-node setup. So I applied your patch to the Compute node and restarted the q-agt service.

When a VM is launched at the Compute node, the correct MTU 9000 is configured at all interfaces and devices:

1. VM eth0 interface:
$ ifconfig eth0 | grep MTU
          UP BROADCAST RUNNING MULTICAST MTU:9000 Metric:1

2. Compute node:
localadmin@qa5:/opt/stack/neutron$ brctl show
bridge name bridge id STP enabled interfaces
brqb5924fb1-0f 8000.6805ca30255b no eth5.300
       tap1425c7b3-f2
virbr0 8000.000000000000 yes

localadmin@qa5:/opt/stack/neutron$ ip -o l | cut -d' ' -f2,5 | grep eth5
eth5: 9000
eth5.300@eth5: 9000

localadmin@qa5:/opt/stack/neutron$ ip -o l | cut -d' ' -f2,5 | grep brq
brqb5924fb1-0f: 9000

localadmin@qa5:/opt/stack/neutron$ ip -o l | cut -d' ' -f2,5 | grep tap
tap1425c7b3-f2: 9000
