  • The Host is not configured for the required networks.

Resolution

1] Place the host Host1 in maintenance.

  Compute --> Hosts --> Select Host Host1 --> Management --> Maintenance

2] Once maintenance is activated, configure networks:

  Click on the hostname Host1 --> Network Interfaces --> Setup Host Networks (Button) --> Configure networks (you can refer to other hosts for the configuration)

3] Activate the host after configuring the networks.

Root Cause

  • The networks were being added via the Clusters with the required option enabled by default and never added via the host . Hence when starting up the vm's the above errors were throwing up . If being added via clusters , the network label requires to be added so that its automatically setup to the Host's network.
