[Bug 1307408] [NEW] VMWare - Destroy fails when Claim is not successful

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

If Claim is not successful, compute manager triggers a call to destroy instance.
Destroy fails since the compute node (cluster) is set only after claim is successful.

This issue occurs when multiple parallel nova boot operations are
triggered simultaneously.
