Cannot find compute service

edit

I setup a controller+network node on Oracle Linux(Kilo), and install a hyper-v compute node following cloudbase doc. But after installation, I can find neutron hyper-v agent, but no related compute services. And I checked that table compute_nodes in nova database is empty. Any idea?

compute service is running correctly on windows 2012 R2. No error message reported on either compute node or controller node.

compute-node.log as below:

The root cause seems I tried using MTU 9000. When I use the default MTU=1500, it works well. But whenever I use MTU 9000, it doesn't work.

What I have updated:

dnsmasq.conf:
dhcp-option-force=26,8950

l3_agent.ini:
[DEFAULT]
network_device_mtu = 8950

ml2_conf.ini:
[ml2]
path_mtu = 8950
segment_mtu = 8950`

nova.conf:
[DEFAULT]
network_device_mtu = 8950

How could I enable mtu 9000?
