Satoru Moriya 3e1a3c9f82 Ironic: Support boot from Cinder volume 
This enables Ironic to boot bare metal machines from Cinder
volume. Ironic virt driver needs to pass the remote volume
connection information down to Ironic when spawning a new
bare metal instance requested to boot from a Cinder volume.

This implements get_volume_connector method for the Ironic
driver. It will get connector information from the Ironic service
and pass it to Cinder's initialize_connection method for attached
volumes. And then it puts the returned value into Ironic.

This patch changes the required Ironic API version to 1.32 for using
new API for volume resources.

# Nova Hypervisor Feature Capability Matrix
# =========================================
#
# This obsoletes the information previously at
#
# https://wiki.openstack.org/wiki/HypervisorSupportMatrix
#
# This file contains a specification of what feature capabilities each
# hypervisor driver in Nova is able to support. Feature capabilities include
# what API operations are supported, what storage / networking features can be
# used and what aspects of the guest machine can be configured. The capabilities
# can be considered to be structured into nested groups, but in this file they
# have been flattened for ease of representation. The section names represent
# the group structure. At the top level there are the following groups defined
#
# - operation - public API operations
# - storage - host storage configuration options
# - networking - host networking configuration options
# - guest - guest hardware configuration options
#
# When considering which capabilities should be marked as mandatory,
# consider the general guiding principles listed in the support-matrix.rst
# file
#
# The 'status' field takes possible values
#
# - mandatory - unconditionally required to be implemented
# - optional - optional to support, nice to have
# - choice(group) - at least one of the options within the named group
# must be implemented
# - conditional(cond) - required, if the referenced condition is met.
#
# The value against each 'driver-impl-XXXX' entry refers to the level
# of the implementation of the feature in that driver
#
# - complete - fully implemented, expected to work at all times
# - partial - implemented, but with caveats about when it will work
# eg some configurations or hardware or guest OS may not
# support it
# - missing - not implemented at all
#
# In the case of the driver being marked as 'partial', then
# 'driver-notes-XXX' entry should be used to explain the caveats
# around the implementation.
#
# The 'cli' field takes a list of nova client commands, separated by semicolon.
# These CLi commands are related to that feature.
# Example:
# cli=nova list;nova show <server>
#
[targets]
# List of driver impls we are going to record info for later
# This list only covers drivers that are in the Nova source
# tree. Out of tree drivers should maintain their own equivalent
# document, and merge it with this when their code merges into
# Nova core.

storage capabilities to be expanded without interruption of
service. In a cloud model it would be more typical to just
spin up a new instance with large storage, so the ability to
hotplug extra storage is for those cases where the instance
is considered to be more of a pet than cattle. Therefore

notes=The attach interface operation provides a means to hotplug
additional interfaces to a running instance. Hotplug support
varies between guest OSes and some guests require a reboot for
new interfaces to be detected. This operation allows interface
capabilities to be expanded without interruption of service.
In a cloud model it would be more typical to just spin up a

[operation.maintenance-mode]
title=Set the host in a maintenance mode

notes=This operation allows a host to be placed into maintenance
mode, automatically triggering migration of any running
instances to an alternative host and preventing new
instances from being launched. This is not considered
to be a mandatory operation to support.
The driver methods to implement are "host_maintenance_mode" and

[operation.evacuate]
title=Evacuate instances from a host
status=optional
notes=A possible failure scenario in a cloud environment is the outage
of one of the compute nodes. In such a case the instances of the down
host can be evacuated to another host. It is assumed that the old host
is unlikely ever to be powered back on, otherwise the evacuation
attempt will be rejected. When the instances get moved to the new
host, their volumes get re-attached and the locally stored data is
dropped. That happens in the same way as a rebuild.
This is not considered to be a mandatory operation to support.

notes=Provides a quick report on information about the guest instance,
including the power state, memory allocation, CPU allocation, number
of vCPUs and cumulative CPU execution time. As well as being
informational, the power state is used by the compute manager for
tracking changes in guests. Therefore this operation is considered

[operation.live-migrate]
title=Live migrate instance across hosts
status=optional
notes=Live migration provides a way to move an instance off one
compute host, to another compute host. Administrators may use
this to evacuate instances from a host that needs to undergo
maintenance tasks, though of course this may not help if the
host is already suffering a failure. In general instances are
considered cattle rather than pets, so it is expected that an
instance is liable to be killed if host maintenance is required.
It is technically challenging for some hypervisors to provide
support for the live migration operation, particularly those
built on the container based virtualization. Therefore this
operation is not considered mandatory to support.

[operation.force-live-migration-to-complete]
title=Force live migration to complete
status=optional
notes=Live migration provides a way to move a running instance to another
compute host. But it can sometimes fail to complete if an instance has
a high rate of memory or disk page access.
This operation provides the user with an option to assist the progress
of the live migration. The mechanism used to complete the live
migration depends on the underlying virtualization subsystem
capabilities. If libvirt/qemu is used and the post-copy feature is
available and enabled then the force complete operation will cause
a switch to post-copy mode. Otherwise the instance will be suspended
until the migration is completed or aborted.

[operation.pause]
title=Stop instance CPUs (pause)
status=optional
notes=Stopping an instances CPUs can be thought of as roughly
equivalent to suspend-to-RAM. The instance is still present
in memory, but execution has stopped. The problem, however,
is that there is no mechanism to inform the guest OS that
this takes place, so upon unpausing, its clocks will no
longer report correct time. For this reason hypervisor vendors
generally discourage use of this feature and some do not even
implement it. Therefore this operation is considered optional
to support in drivers.

[operation.reboot]
title=Reboot instance
status=optional
notes=It is reasonable for a guest OS administrator to trigger a
graceful reboot from inside the instance. A host initiated
graceful reboot requires guest co-operation and a non-graceful

this operation is considered optional.

[operation.rescue]
title=Rescue instance
status=optional
notes=The rescue operation starts an instance in a special
configuration whereby it is booted from an special root
disk image. The goal is to allow an administrator to
recover the state of a broken virtual machine. In general
the cloud model considers instances to be cattle, so if
an instance breaks the general expectation is that it be
thrown away and a new instance created. Therefore this
operation is considered optional to support in drivers.

notes=The resize operation allows the user to change a running
instance to match the size of a different flavor from the one
it was initially launched with. There are many different
flavor attributes that potentially need to be updated. In
general it is technically challenging for a hypervisor to
support the alteration of all relevant config settings for a
running instance. Therefore this operation is considered

[operation.set-admin-password]
title=Set instance admin password
status=optional
notes=Provides a mechanism to (re)set the password of the administrator
account inside the instance operating system. This requires that the
hypervisor has a way to communicate with the running guest operating
system. Given the wide range of operating systems in existence it is
unreasonable to expect this to be practical in the general case. The
configdrive and metadata service both provide a mechanism for setting
the administrator password at initial boot time. In the case where this
operation were not available, the administrator would simply have to
login to the guest and change the password in the normal manner, so
this is just a convenient optimization. Therefore this operation is
not considered mandatory for drivers to support.

[operation.snapshot]
title=Save snapshot of instance disk
status=optional
notes=The snapshot operation allows the current state of the
instance root disk to be saved and uploaded back into the
glance image repository. The instance can later be booted
again using this saved image. This is in effect making
the ephemeral instance root disk into a semi-persistent
storage, in so much as it is preserved even though the guest
is no longer running. In general though, the expectation is
that the root disks are ephemeral so the ability to take a
snapshot cannot be assumed. Therefore this operation is not
considered mandatory to support.

[operation.suspend]
title=Suspend instance
status=optional
notes=Suspending an instance can be thought of as roughly
equivalent to suspend-to-disk. The instance no longer
consumes any RAM or CPUs, with its live running state
having been preserved in a file on disk. It can later
be restored, at which point it should continue execution
where it left off. As with stopping instance CPUs, it suffers from the fact
that the guest OS will typically be left with a clock that
is no longer telling correct time. For container based
virtualization solutions, this operation is particularly
technically challenging to implement and is an area of
active research. This operation tends to make more sense
when thinking of instances as pets, rather than cattle,
since with cattle it would be simpler to just terminate
the instance instead of suspending. Therefore this operation
is considered optional to support.

[operation.swap-volume]
title=Swap block volumes
status=optional
notes=The swap volume operation is a mechanism for changing a running
instance so that its attached volume(s) are backed by different
storage in the host. An alternative to this would be to simply
terminate the existing instance and spawn a new instance with the
new storage. In other words this operation is primarily targeted towards
the pet use case rather than cattle, however, it is required for volume
migration to work in the volume service. This is considered optional to
support.

notes=Block storage provides instances with direct attached
virtual disks that can be used for persistent storage of data.
As an alternative to direct attached disks, an instance may
choose to use network based persistent storage. OpenStack provides
object storage via the Swift service, or a traditional filesystem
such as NFS may be used. Some types of instances may
not require persistent storage at all, being simple transaction
processing systems reading requests & sending results to and from
the network. Therefore support for this configuration is not
considered mandatory for drivers to support.

This isolates the compute layer for knowledge of the specific storage
technology used by Cinder, albeit at a potential performance cost due
to the longer I/O path involved. If the driver chooses to support
block storage, then this is considered mandatory to support, otherwise
it is considered optional.
