標籤：啟動執行個體失敗   nova-compute.log 報出 instance failed network setup after 1 attempt(s)   

在啟動 openstack 的執行個體時報出:650) this.width=650;" src="https://s2.51cto.com/wyfs02/M01/9B/49/wKiom1lg2W3j4JkIAAAr8pdC_kI746.png-wh_500x0-wm_3-wmp_4-s_59788958.png" title="粘貼圖片.png" alt="wKiom1lg2W3j4JkIAAAr8pdC_kI746.png-wh_50" />

後面查看 nova-compute.log，發現：

2017-07-06 14:38:27.839 5943 ERROR nova.compute.manager [req-0cda8b99-7837-493a-bf3c-26c0649be541 22a99702c9074c6c876dc7698cf91375 c66fe3ac25a74149bef9b187ad8d4543 - - -] Instance failed network setup after 1 attempt(s)

後面查看 nova-conductor.log，發現：

2017-07-06 14:30:31.975 6051 WARNING oslo_config.cfg [req-1252606a-8e2c-4488-9a86-3c8ef7038fbc 22a99702c9074c6c876dc7698cf91375 c66fe3ac25a74149bef9b187ad8d4543 - - -] Option "auth_plugin" from group "neutron" is deprecated. Use option "auth_type" from group "neutron".

通過日誌，發現可能是網路方面的問題。通過排查將 /etc/nova/nova.conf

[neutron]

url = http://controller:9696

auth_url = http://controller:35357

auth_plugin = password              《--- 有問題

project_domain_id = default         《--- 有問題

user_domain_id = default            《--- 有問題

region_name = RegionOne

project_name = service

username = neutron

password = passw0rd

service_metadata_proxy = True

metadata_proxy_shared_secret = passw0rd

改成：

[neutron]

url = http://controller:9696

auth_url = http://controller:35357

auth_type = password

project_domain_name = default

user_domain_name = default

region_name = RegionOne

project_name = service

username = neutron

password = passw0rd

service_metadata_proxy = True

metadata_proxy_shared_secret = passw0rd

重啟相關的服務：systemctl restart openstack-nova-compute.service neutron-server.service openstack-nova-api.service

重新建立執行個體OK！！！
