    compute: Skip driver detach calls for non local instances
    
    Only call for a driver detach from a volume if the instance is currently
    associated with the local compute host. This avoids potential virt
    driver and volume backend issues when attempting to disconnect from
    volumes that have never been connected to from the current host.

Title:
  disconnect_volume calls are made during a remote rebuild of a volume
  backed instance

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Description
  ===========
  disconnect_volume calls are made during a remote rebuild of a volume backed instance

  Steps to reproduce
  ==================
  - Evacuate a volume backed instance.
  - disconnect_volume is called for each previously attached volume on the now remote node rebuilding the instance.

  Expected result
  ===============
  disconnect_volume is not called unless the instance was previously running on the current host.

  Actual result
  =============
  disconnect_volume is called regardless of the instance previously running on the current host.

  Environment
  ===========
  1. Exact version of OpenStack you are running. See the following
    list for all releases: http://docs.openstack.org/releases/

     Multinode devstack

  2. Which hypervisor did you use?
     (For example: Libvirt + KVM, Libvirt + XEN, Hyper-V, PowerKVM, ...)

     libvirt + KVM

  2. Which storage type did you use?
     (For example: Ceph, LVM, GPFS, ...)
     What's the version of that?

     LVM/iSCSI

  3. Which networking type did you use?
     (For example: nova-network, Neutron with OpenVSwitch, ...)
    
     N/A
