melanie witt 3051a0d5d5 Make scheduler.utils.setup_instance_group query all cells
To check affinity and anti-affinity policies for scheduling instances,
we use the RequestSpec.instance_group.hosts field to check the hosts
that have group members on them. Access of the 'hosts' field calls
InstanceGroup.get_hosts during a lazy-load and get_hosts does a query
for all instances that are members of the group and returns their hosts
after removing duplicates. The InstanceList query isn't targeting any
cells, so it will return [] in a multi-cell environment in both the
instance create case and the instance move case. In the move case, we
do have a cell-targeted RequestContext when setup_instance_group is
called *but* the RequestSpec.instance_group object is queried early in
compute/api before we're targeted to a cell, so a call of
RequestSpec.instance_group.get_hosts() will result in [] still, even
for move operations.

This makes setup_instance_group query all cells for instances that are
members of the instance group if the RequestContext is untargeted, else
it queries the targeted cell for the instances.

Closes-Bug: #1746863

OpenStack Nova

OpenStack Nova provides a cloud computing fabric controller, supporting a wide variety of compute technologies, including: libvirt (KVM, Xen, LXC and more), Hyper-V, VMware, XenServer, OpenStack Ironic and PowerVM.

Use the following resources to learn more.

API

To learn how to use Nova's API, consult the documentation available online at:

Operators

To learn how to deploy and configure OpenStack Nova, consult the documentation available online at:

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers

For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.

Any new code must follow the development guidelines detailed in the HACKING.rst file, and pass all unit tests.
