The filter-scheduler doc was pretty old and I was recently asked to give
some guidance on how to create a custom filter.
A doc is better than any chat, so let's make that better.

The docs were using variable names from the filter code rather
than the actual config options.

Nova has two pages in documentation listing things supported on several
architectures/hypervisors. This patch adds initial state of AArch64
into support matrix.
Document minimal qemu/libvirt for aarch64. Version 3.6.0 was first one
which worked for us with Nova without a need for extra patches.

The affinity and anti-affinity server group policy is enforced by the
scheduler but two parallel scheduling could cause that such policy is
violated. During instance boot a late policy check was performed in
the compute manager to prevent this. This check was missing in case
of rebuild. Therefore two parallel evacuate command could cause that
the server group policy is violated. This patch introduces the late
policy check to rebuild to prevent such situation. When the violation
is detected during boot a re-scheduling happens. However the rebuild
action does not have the re-scheduling implementation so in this case
the rebuild will fail and the evacuation needs to be retried by the
user. Still this is better than allowing a parallel evacuation to
break the server group affinity policy.
To make the late policy check possible in the compute/manager the
rebuild_instance compute RPC call was extended with a request_spec
parameter.

Now that Queens supports attaching virtual GPUs to an instance, we need to
properly document which hypervisors support that, how to use that feature and
what the existing caveats are.

This adds a mention of the nova-scheduler service requiring
placement 1.17 and also links to the placement upgrade notes
from the more general upgrade notes, since we are now firmly
in a place where placement needs to be upgraded before nova.
Since we consider placement global, this removes the 1.14
note about nova-compute since we assume that if you're going
to upgrade placement to get 1.17 for the scheduler, and control
services should be upgraded before computes, then the computes
are going to get a new enough placement service automatically.

This is a follow up to Ie039322660fd0e2e0403843448379b78114c425b.
A few things are changed here:
* The note about using file injection is removed. File injection
was deprecated in the API in Queens and not something that we
really want users using.
* Mention that creating a flavor is typically admin-only.
* Link to the BDM docs for more details about BDM parameter values.
* Update the manage-ip-address docs to make the examples rely on
using the networking resource CLIs rather than any proxy APIs
that were available in nova.

This imports the "launch instance" end user guide docs from
the openstack-manuals repo. As part of the docs migration
in Pike, these were forgotten. The copied contents come from
the stable/ocata branch of openstack-manuals, and therefore
likely need some updating, but that could be done in follow up
changes. This is an initial import to (1) publish the content
again somewhere and (2) fix broken links in the cinder docs
for booting from volume.

This change introduces a new microversion which must be used
to create a server from a multiattach volume or attach a multiattach
volume to an existing server instance.
Attaching a multiattach volume to a shelved offloaded instance is not
supported since an instance in that state does not have a compute host
so we can't tell if the compute would support the multiattach volume
or not. This is consistent with the tagged attach validation with 2.49.
When creating a server from a multiattach volume, we'll check to see
if all computes in all cells are upgraded to the point of even supporting
the compute side changes, otherwise the server create request fails with
a 409. We do this because we don't know which compute node the scheduler
will pick and we don't have any compute capability filtering in the
scheduler for multiattach volumes (that may be a future improvement).
Similarly, when attaching a multiattach volume to an existing instance,
if the compute isn't new enough to support multiattach or the virt
driver simply doesn't support the capability, a 409 response is returned.
Presumably, operators will use AZs/aggregates to organize which hosts
support multiattach if they have a mixed hypervisor deployment, or will
simply disable multiattach support via Cinder policy.
The unit tests are covering error conditions with the new flow. A new
functional scenario test is added for happy path testing of the new boot
from multiattach volume flow and attaching a multiattach volume to more
than one instance.
Tempest integration testing for multiattach is added in change
I80c20914c03d7371e798ca3567c37307a0d54aaa.
Devstack support for multiattach is added in change

The cells v2 layout documentation clearly states that there are no
upcalls from cells back to the central API services. This mislead
me for sometime as I could not fathom how a compute node in a cell
was supposed to report its resource info.
It turns out nova looks up the placement service in the keystone
catalogue and contacts it directly which to my mind is an upcall. I
wonder if the author of the not felt that the placement service is
not really part of nova?

This filter relies on the flavor.id primary key which will
change as (1) flavors were migrated to the API database and
(2) when a flavor is changed by deleting and re-creating the
flavor.
Also, as noted in blueprint put-host-manager-instance-info-on-a-diet,
this is one step forward in getting us to a point where the only
thing that the in-tree filters care about in the HostState.instances
dict is the instance uuid (for the affinity filters). Which means
we can eventually stop RPC casting all instance information from
all nova-compute services to the scheduler for every instance create,
delete, move or periodic sync task - we only would need to send the
list of instance UUIDs. That should help with RPC traffic in a large
and busy deployment.

With change I2f367b06e683ed7c815dd9e0536a46e5f0a27e6c, nova-compute
now unconditionally requires Placement 1.14 to be available (the

trying to use it).
This change updates the nova-status check for the minimum required
version of Placement and also starts the "Queens" section of the
Placement upgrade notes docs.

Commit ace11d3 adds a serial port device to instances, so the serial
console output can be sent to a virtual serial port concentrator (VSPC).
This patch finishes the implementation by returning the output saved by
VSPC to the end user. The config option 'serial_log_dir' should have the
same value as in the VSPC configuration (i.e. it must point to the same
directory).

3. Removes a note about liberty being the current release.
4. Adds a link in the API reference parameters to actually
