The root disk image is moved to a separate disk slot while the rescue image will take it's place. If the instance requires it, a temporary config drive is created as well. Unrescuing the instance will move the root disk image back in place, removing temporary images. DocImpact Implements: blueprint hyper-v-rescue Change-Id: I6059ae35a77d675f54b98b2b43b5762e1d24365b

# 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.

notes=The attach volume operation provides a means to hotplug

additional block storage to a running instance. This allows

|
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

this operation is not considered to be mandatory to support.

|
|
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.

[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.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.

graceful reboot requires guest co-operation and a non-graceful

|
reboot can be achieved by a combination of stop+start. Therefore

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

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

[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.

|
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

status=condition(storage.block==complete)
|
|
notes=If the driver wishes to support block storage, it is common to
|
|
provide an iSCSI based backend to access the storage from cinder.
|
|
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.

a mandatory storage feature to support.

In a private cloud environment this may be considered to be a

superfluous requirement. Therefore this is considered to be an

optional configuration to support.
