"'device_type': 'type-VF'" to the '[pci] alias' configuration option.

Get excited, people. It's finally dying, for real. There is a lot more
doc work needed here, but this is a start. No need for a release note
modification since we've already said that nova-network has been
removed, so there's no point in saying that the service itself has been
removed since that's implicit.

The majority if this doc was talking about ec2 concepts
which haven't been in nova for a looooong time so this
change just deletes the doc and moves the one useful
piece into another part of the admin guide and links to
the keystone docs.

Yet another one of these. This time around, we make the following
changes:
- Put admin-focused stuff in '/admin', and user-focused docs in '/user'
- Merge the '/admin/quotas2' document into the '/admin/quotas' document
- Update references to novaclient to use openstackclient if possible and
include a TODO if not
- s/tenant/project/
Note that there is some duplication between the user and admin docs
here. That's necessary since, for example, showing a user's quotas is
also something an admin will want to do.

These made things significantly less discoverable from the admin guide
and resulted in some duplication of links. Better to just flatten
things. Things are pretty much copy-pasted save for the removal of a
reference to the long-dead nova-objectstore service and the addition of
a TODO to provide overviews of other services.

It doesn't really make sense to describe the "higher level"

While we do not have an automated fix for bug 1849479 this provides
a troubleshooting document for working around that issue where
allocations from a server that was evacuated from a down host need
to be cleaned up manually in order to delete the resource provider
and associated compute node/service.
In general this is also a useful guide for linking up the various
resources and terms in nova and how they are reflected in placement
with the relevant commands which is probably something we should
do more of in our docs.

cache-related conf options into it.

Partial-Bug: #1847302
If we're booting from an existing volume but the instance is not being
created in a requested availability zone, and cross_az_attach=False,
we'll fail with a 400 since by default the volume is in the 'nova'
AZ and the instance does not have an AZ set - because one wasn't requested
and because it's not in a host aggregate yet.
This refactors that AZ validation during server create in the API to
do it before calling _validate_bdm so we get the pre-existing volumes
early and if cross_az_attach=False, we validate the volume zone(s) against
the instance AZ. If the [DEFAULT]/default_schedule_zone (for instances) is
not set and the volume AZ does not match the
[DEFAULT]/default_availability_zone then we put the volume AZ in the request
spec as if the user requested that AZ when creating the server.
Since this is a change in how cross_az_attach is used and how the instance
default AZ works when using BDMs for pre-existing volumes, the docs are
updated and a release note is added.
Note that not all of the API code paths are unit tested because the
functional test coverage does most of the heavy lifting for coverage.
Given the amount of unit tests that are impacted by this change, it is
pretty obvious that (1) many unit tests are mocking at too low a level and
(2) functional tests are better for validating these flows.

This adds AggregateCacheNotification, related payload, and code in
conductor to emit this per-compute with progress information. This
also adds a "progress" phase to NotificationPhase, which allows for
start..progress..progress..end information for a single operation
(cache_images in this case).

These closely related features are the source of a disproportionate
number of bugs and a large amount of confusion among users. The spread
of information around multiple docs probably doesn't help matters.
Do what we've already done for the metadata service and remote consoles
and clean these docs up. There are a number of important changes:
- All documentation related to host aggregates and availability zones is
placed in one of three documents, '/user/availability-zones',
'/admin/aggregates' and '/admin/availability-zones'. (note that there
is no '/user/aggregates' document since this is not user-facing)
- References to these features are updated to point to the new location
- A glossary is added. Currently this only contains definitions for host
aggregates and availability zones
- nova CLI commands are replaced with their openstack CLI counterparts
- Some gaps in related documentation are closed

Thank God. The majority of the removed images are so crufty, it's
actually funny. I don't want to update them and it's unlikely anyone
else does either. The rest are just moved to be with their comrades in

We don't need to do a whole lot here. The key things to note are that
some host level configuration is now necessary, that the 'isolate' CPU
thread policy behaves slightly differently, and that you can request
'PCPU' inventory explicitly instead of using 'hw:cpu_policy=dedicated'
or the image metadata equivalent.

The documentation for emulator threads leaves a lot to be desired, while
the hierarchy of the CPU thread pinning doesn't emphasise the dependency
of this feature on CPU pinning. Resolve both by tweaking or expanding
the wording of key paragraphs and modifying the header levels to nest
the CPU thread pinning and emulator thread pinning docs under the CPU
pinning docs.

This is a follow-up to the previous SEV commit which enables booting
SEV guests (I659cb77f12a3), making some minor improvements based on
nits highlighted during review:
- Clarify in the hypervisor-kvm.rst documentation that the
num_memory_encrypted_guests option is optional, by rewording and
moving it to the list of optional steps.
- Make things a bit more concise and avoid duplication of information
between the above page and the documentation for the option
num_memory_encrypted_guests, instead relying on appropriate
hyperlinking between them.
- Clarify that virtio-blk can be used for boot disks in newer kernels.
- Hyperlink to a page explaining vhost-user
- Remove an unneeded mocking of a LOG object.
- A few other grammar / spelling tweaks.

Track compute node inventory for the new MEM_ENCRYPTION_CONTEXT
resource class (added in os-resource-classes 0.4.0) which represents
the number of guests a compute node can host concurrently with memory
encrypted at the hardware level.
This serves as a "master switch" for enabling SEV functionality, since
all the code which takes advantage of the presence of this inventory
in order to boot SEV-enabled guests is already in place, but none of
it gets used until the inventory is non-zero.
A discrete inventory is required because on AMD SEV-capable hardware,
the memory controller has a fixed number of slots for holding
encryption keys, one per guest. Typical early hardware only has 15
slots, thereby limiting the number of SEV guests which can be run
concurrently to 15. nova needs to track how many slots are available
and used in order to avoid attempting to exceed that limit in the
hardware.
Work is in progress to allow QEMU and libvirt to expose the number of
slots available on SEV hardware; however until this is finished and
released, it will not be possible for nova to programatically detect
the correct value with which to populate the MEM_ENCRYPTION_CONTEXT
inventory. So as a stop-gap, populate the inventory using the value
manually provided by the cloud operator in a new configuration option
CONF.libvirt.num_memory_encrypted_guests.
Since this commit effectively enables SEV, also add all the relevant
documentation as planned in the AMD SEV spec[0]:
- Add operation.boot-encrypted-vm to the KVM hypervisor feature matrix.
- Update the KVM section of the Configuration Guide.
- Update the flavors section of the User Guide.
- Add a release note.

After three months since the quality warning change merged [1]
there has still been no progress in finding a maintainer for
the xenapi driver or someone to get the third party CI running
again - which has been off/broken for more than a release.
This change formally deprecates the driver, logging a warning
on startup along with providing a release note and warnings
in the docs and [xenserver] config group help.
Note that this does not mean the driver will absolutely be
removed in the Ussuri release, but it leaves the option open
to do so if the nova team decides that should happen.
This was discussed at the 2019-09-05 nova meeting [2] and
also at the Train PTG.
