The completely fix this bug we also need
https://review.openstack.org/#/c/69262/. This patch makes sure that the
driver lists only the instances of it's nodes. Currently, it lists all
the vm's that are with the hypervisor even the ones not managed by its
nodes.

Title:
  VMware driver: Nova compute fails to start when multiple nova compute
  services are running per vCenter.

Status in OpenStack Compute (Nova):
  In Progress
Status in The OpenStack VMwareAPI subTeam:
  In Progress

Bug description:
  Nova Compute fails to start when there are multiple nova compute
  services  running on different VMs(nova compute VMs) and each Vm
  managing multiple cluster in a vCenter and instances are provisioned
  on them.

  Explanation:

  Lets say, one nova compute vm(C1) is managing 5 clusters, and
  another(C2) managing 5 clusters. C1 manages n number of instances.
  Suppose in C2 compute service gets restarted, it fails to start.

  Reason:
  on the start up of the nova-compute,  it checks the instances reported by the driver are still associated with this host.  If they are  not, it destroys them.
  method _destroy_evacuated_instances calls the driver list_instances, which lists all the instances in the vCenter, though they are managed by different compute. Instead it should return only the vms which are managed by c1/c2.

  log file attached.
