[Bug 1340167] [NEW] VMware: Horizon reports incorrect message for PAUSE instance

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

When I pause an instance hosted on VMware cluster, it shows 
SUCCESS: Paused Instance: <instance_name>; 
in horizon portal and nothing happens (instance does not go to Pause state)

In nova-compute log it shows: pause not supported for vmwareapi
