NOTE:

當VM開機後等很久才要到IP，或是出現169.254.X.X這Metadata位址無法連線上的都是Metadata的原因。但請先確認farbirc網路是互通的。

Metadata (MD) not working

• In /etc/neutron/plugins/plumgrid/plumlib.ini on each node

  nova_metadata_ip = 169.254.169.254
  nova_metadata_subnet = 169.254.169.254/30
  nova_metadata_port = 8775
  metadata_proxy_shared_secret = secret
  enable_pg_metadata = True
  

  NOTE:檢查 /etc/nova.conf 裡的metadata_proxy_shared_secrete是否與這裡的metadata_proxy_shared_secrete一致。

  metadata_proxy_shared_secret = secret
  

• Install openstack-nova-api on compute

yum install openstack-nova-api
systemctl enable openstack-nova-metadata-api
systemctl start openstack-nova-metadata-api

• Check nova.conf

  metadata_proxy_shared_secret= secret
  service_metadata_proxy=True
  

  NOTE: metadata_proxy_shared_secret= secret 必須跟/etc/neutron/plugins/plumgrid/plumlib.ini裡的一樣

• 檢查memtadata listen port on Conpute to verify MetaData is working

curl 127.0.0.1:8775

• Check VM has MD.

Note: Already created Tenants might not work, check by creating a new tenant. For already created tenants, delete all VNFs and delete default SG to enable new MD configurations to be pushed
