On execution of nova host-update compute-01 --maintenance enable I see that it errors out with VMwareVCDriver and other side effect of this is that it puts the first host in the Cluster in the maintenance mode. Better to mark this operation in VMwareVCDriver as NotImplemented to avoid this side effect until a permanent solution is added.

Hi,
The problem occurs when there is more than one host in the cluster
Thanks
Gary

[Gary Kotton (garyk)]

These operations are unable to supported with the cluster. Following your suggestion they will be NotImplemented. The work around would be for the administrator to set them accordingly in the VC.

    VMware: bug fix for host operations when using VMwareVCDriver

    Currently the driver does not have a mapping between a Nova 'host'
    and a VMware 'cluster'. A host operation would update the state of
    one of the hosts in one of the configured clusters.

    The solution is for the driver to raise a NotImplemented exception.
