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.

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

With Libvirt v8.7.0+, the <maxphysaddr> sub-element
of the <cpu> element specifies the number of vCPU
physical address bits [1].
[1] https://libvirt.org/news.html#v8-7-0-2022-09-01
New flavor extra_specs and image properties are added to
control the physical address bits of vCPUs in Libvirt guests.
The nova-scheduler requests COMPUTE_ADDRESS_SPACE_* traits
based on them. The traits are already defined in os-traits
v2.10.0. Also numerical comparisons are performed at
both compute capabilities filter and image props filter.

When people transition from three ironic nova-compute processes down
to one process, we need a way to move the ironic nodes, and any
associcated instances, between nova-compute processes.
For saftey, a nova-compute process must first be forced_down via
the API, similar to when using evacaute, before moving the associated
ironic nodes to another nova-compute process. The destination
nova-compute process should ideally not be running, but not forced
down.

Ironic in API 1.82 added the option for nodes to be associated with
a specific shard key. This can be used to partition up the nodes within
a single ironic conductor group into smaller sets of nodes that can
each be managed by their own nova-compute ironic service.
We add a new [ironic]shard config option to allow operators to say
which shard each nova-compute process should target.
As such, when the shard is set we ignore the peer_list setting
and always have a hash ring of one.
Also corrects an issue where [ironic]/conductor_group was considered
a mutable configuration; it is not mutable, nor is shards. In any
situation where an operator changes the scope of nodes managed by a
nova compute process, a restart is required.

Nova Hyper-V driver is not tested in OpenStack upstream and no maintianers.

list_instances and list_instance_uuids, as written in the Ironic driver,
do not currently respect conductor_group paritioning. Given a nova
compute is intended to limit it's scope of work to the conductor group
it is configured to work with; this is a bug.
Additionally, this should be a significant performance boost for a
couple of reasons; firstly, instead of calling the Ironic API and
getting all nodes, instead of the subset (when using conductor group),
we're now properly getting the subset of nodes -- this is the optimized
path in the Ironic DB and API code. Secondly, we're now using the
driver's node cache to respond to these requests. Since list_instances
and list_instance_uuids is used by periodic tasks, these operating with
data that may be slightly stale should have minimal impact compared to
the performance benefits.

In I008841988547573878c4e06e82f0fa55084e51b5 we started enabling a
bunch of libvirt enlightenments for Windows unconditionally. Turns
out, the `evmcs` enlightenment only works on Intel hosts, and we broke
the ability to run Windows guests on AMD machines. Until we become
smarter about conditionally enabling evmcs (with something like traits
for host CPU features), just stop enabling it at all.

Libvirt has implemented the capability to expose maximum number of
SEV guests and SEV-ES guests in 8.0.0[1][2]. This allows nova to detect
maximum number of memory encrypted guests using that feature.
The detection is not used if the [libvirt] num_memory_encrypted_guests
option is set to preserve the current behavior.
Note that current nova supports only SEV and does not support SEV-ES,
so this implementation only uses the maximum number of SEV guests.
The maximum number of SEV-ES guests will be used in case we implement
support for SEV-ES.

The CPU power management feature of the libvirt driver, enabled with
[libvirt]cpu_power_management, only manages dedicated CPUs and does not
touch share CPUs. Today nova-compute refuses to start if configured
with [libvirt]cpu_power_management=true [compute]cpu_dedicated_set=None.
While this is functionally not limiting it does limit the possibility to
independently enable the power management and define the
cpu_dedicated_set. E.g. there might be a need to enable the former in
the whole cloud in a single step, while not all nodes of the cloud will
have dedicated CPUs configured.
This patch removes the strict config check. The implementation already
handles each PCPU individually, so if there are an empty list of PCPUs
then it does nothing.

For live migration the libvirt driver already supports generating the
migration URL based on the compute host hostname if so configured.
However for the non live move operations the driver always used the IP
address of the compute host based on [DEFAULT]my_ip.
Some deployments rely on DNS to abstract the IP address management. In
these environments it is beneficial if nova allows connection between
compute hosts based on the hostname (or FQDN) of the host instead of
trying to configure [DEFAUL]my_ip to an IP address.
This patch introduces a new config option
[libvirt]migration_inbound_addr that is used to determine the address
for incoming move operations (cold migrate, resize, evacuate). This
config is defaulted to [DEFAULT]my_ip to keep the configuration backward
compatible. However it allows an explicit hostname or FQDN to be
specified, or allows to specify '%s' that is then resolved to the
hostname of compute host.

Libvirt's node device driver accumulates and reports information
about host devices. Network capabilities reported by node device
driver for NIC contain information about HW offloads supported
by this NIC.
One of possible features reported by node device driver is
switchdev: a NIC capability to implement VFs similar to actual
HW switch ports (also referred to as SR-IOV OVS hardware offload).
From Neutron perspective, vnic-type should be set to "direct" and
"switchdev" capability should be added to port binding profile to
enable HW offload (there are also configuration steps on compute
hosts to tune NIC config).
This patch was written to automatically translate "switchdev" from
VF network capabilities reported by node device driver to Neutron
port binding profile and allow user to skip manual step that
requires admin privileges.
Other capabilities are also translated: they are not used right
now, but provide visibility and can be utilized later.
