We agreed by I2dd906f34118da02783bb7755e0d6c2a2b88eb5d on the support
envelope.
Pre-RC1, we need to add a service version in the object.
Post-RC1, depending on whether it's SLURP or not SLURP, we need to bump
the minimum version or not.
This patch only focuses on pre-RC1 stage.
Given Dalmatian will be skippable, we will need a post-RC1 patch for updating the min
that will bump to Caracal.
HTH.

Previously, live migrations completely ignored CPU power management.
This patch makes sure that we correctly:
* Power up the cores on the destination during pre_live_migration, as
we need them powered up before the instance starts on the
destination.
* If the live migration is successful, power down the vacated cores on
the source.
* In case of a rollback, power down the cores previously powered up on
pre_live_migration.

Building on the previous patch's refactor, we can now do functional
testing of live migration with CPU power management. We quickly notice
that it's mostly broken, leaving the CPUs powered up on the source,
and not powering them up on the dest.

We want to test power management in our functional tests in multinode
scenarios (ex: live migration).
This was previously impossible because all the methods in
nova.virt.libvirt.cpu.api and were at the module level, meaning both
source and destination libvirt drivers would call the same method to
online and offline cores. This made it impossible to maintain distinct
core power state between source and destination.
This patch inserts a nova.virt.libvirt.cpu.api.API class, and gives
the libvirt driver a cpu_api attribute with an instance of that
class. Along with the tiny API.core() helper, this allows new
functional tests in the subsequent patches to stub out the core
"model" code with distinct objects on the source and destination
libvirt drivers, and enables a whole bunch of testing (and fixes!)
around live migration.

Previously, with the `isolate` emulator threads policy and libvirt cpu
power management enabled, we did not power on the cores to which the
emulator threads were pin. Start doing that, and don't forget to power
them down when the instance is stopped.

When we pin emulator threads with the `isolate` policy, those pins are
stored in the `cpuset_reserved` field in each NUMACell. In subsequent
patches we'll need those pins for the whole instance, so this patch
adds a helper property that does this for us, similar to how the
`cpu_pinning` property helper currently works.

We want to cap a maximum mdevs we can create.
If some type has enough capacity, then other GPUs won't be used and
existing ResourceProviders would be deleted.

As of now, the server show and server list --long output
shows the availability zone, that is, the AZ to which the
host of the instance belongs. There is no way to tell from
this information if the instance create request included an
AZ or not.
This change adds a new api microversion to add support for
including availability zone requested during instance create
in server show and server list --long responses.

This was a TODO to remove delete attachment call from refresh after
remove_volume_connection call.
Remove volume connection process itself deletes attachment on passing
delete_attachment flag.

There were cases where the instance said to live in compute#1 but the
connection_info in the BDM record was for compute#2, and when the script
called `remote_volume_connection` then nova would call os-brick on
compute#1 (the wrong node) and try to detach it.
In some case os-brick would mistakenly think that the volume was
attached (because the target and lun matched an existing volume on the
host) and would try to disconnect, resulting in errors on the compute
logs.

the existing ironic-tempest-ipa-wholedisk-direct-tinyipa-multinode
job in the experimental line.
&policies-irrelevant-files is moved to the job defintions to
make workign on jobs simpler when commeting out jobs during devleopemt
yes this is unrelated but it make our lives simpler.

Add some notes and clarify some details:
- You don't *have* to specify an IP protocol: non-IP Ethertypes are
possible
- It is not possible to automatically create ports *without* the default
SG (nor will it ever be possible - proxy APIs are bad)
- Remove the default SG can break access to the metadata service

Now the destination returns the list of the needed mdevs for the
migration, we can change the XML.
Note: this is the last patch of the feature branch.
I'll work on adding mtty support in the next patches in the series
but that's not a feature usage.
