Prepare for new checkpoint and backup APIs by describing the XML
that will represent a checkpoint and backup. The checkpoint XML
is modeled heavily after virDomainSnapshotPtr, since both represent
a point in time of the guest (however, a snapshot exists with the
intent to roll back to that point, while a checkpoint exists to
facilitate later incremental backups). Meanwhile, the backup XML
has enough information to represent both push model (the hypervisor
writes the backup file to a location of the user's choice) and the
pull model (the hypervisor needs local temporary storage, and also
creates an NBD server that the user can use to read the backup via
a third-party client).. But while a snapshot exists with the
intent of rolling back to that state, a checkpoint instead makes it
possible to create an incremental backup at a later time.
Add testsuite coverage for some minimal uses of both XML.
Ultimately, I'd love for push model backups to target a network
driver rather than just a local file or block device; but doing
that got hairy (while <domain> uses <source> as the description
of a host or network resource, I picked <target> as the description
of a push model backup target [defaults to qcow2 but can also be
raw or any other format], and <scratch> as the description
of a pull model backup scratch space [must be qcow2]). The ideal
refactoring would be a way to parameterize RNG to accept
<disk type='FOO'>...</disk> so that the name of the subelement
can be <source> for domain, or <target> or <scratch> as needed for
backups. Future patches may improve this area of code.

An updated version of the XML descriptions, while I still work on
piecing together the pieces needed to demo the XML in action.
Missing changes that were pointed out by John, but also supplies
the <domainbackup> XML that was previously a black box.

XML</a></h2>
+
+ <p>
+ Domain disk backups, including incremental backups, are one form
+ of <a href="domainstatecapture.html">domain state
capture</a>.
+ </p>
+ <p>
+ Libvirt is able to facilitate incremental backups by tracking
+ disk checkpoints, or points in time against which it is easy to
+ compute which portion of the disk has changed. Given a full
+ backup (a backup created from the creation of the disk to a
+ given point in time, coupled with the creation of a disk
+ checkpoint at that time), and an incremental backup (a backup
+ created from just the dirty portion of the disk between the
+ first checkpoint and the second backup operation), it is
+ possible to do an offline reconstruction of the state of the
+ disk at the time of the second backup, without having to copy as
+ much data as a second full backup would require. Most disk
+ checkpoints are created in concert with a backup,
+ via <code>virDomainBackupBegin()</code>; however, libvirt also
+ exposes enough support to create disk checkpoints independently
+ from a backup operation,
+ via <code>virDomainCheckpointCreateXML()</code>.
+ </p>
+ <p>
+ Attributes of libvirt checkpoints are stored as child elements of
+ the <code>domaincheckpoint</code> element. At checkpoint creation
+ time, normally only the <code>name</code>,
<code>description</code>,
+ and <code>disks</code> elements are settable; the rest of the
+ fields are ignored on creation, and will be filled in by
+ libvirt in for informational purposes
+ by <code>virDomainCheckpointGetXMLDesc()</code>. However, when
+ redefining a checkpoint,
+ with the <code>VIR_DOMAIN_CHECKPOINT_CREATE_REDEFINE</code> flag
+ of <code>virDomainCheckpointCreateXML()</code>, all of the XML
+ described here is relevant.
+ </p>
+ <p>
+ Checkpoints are maintained in a hierarchy. A domain can have a
+ current checkpoint, which is the most recent checkpoint compared to
+ the current state of the domain (although a domain might have
+ checkpoints without a current checkpoint, if checkpoints have been
+ deleted in the meantime). Creating or reverting to a checkpoint
+ sets that checkpoint as current, and the prior current checkpoint is
+ the parent of the new checkpoint. Branches in the hierarchy can
+ be formed by reverting to a checkpoint with a child, then creating
+ another checkpoint.
+ </p>
+ <p>
+ The top-level <code>domaincheckpoint</code> element may contain
+ the following elements:
+ </p>
+ <dl>
+ <dt><code>name</code></dt>
+ <dd>The name for this checkpoint. If the name is specified when
+ initially creating the checkpoint, then the checkpoint will have
+ that particular name. If the name is omitted when initially
+ creating the checkpoint, then libvirt will make up a name for
+ the checkpoint, based on the time when it was created.
+ </dd>
+ <dt><code>description</code></dt>
+ <dd>A human-readable description of the checkpoint. If the
+ description is omitted when initially creating the checkpoint,
+ then this field will be empty.
+ </dd>
+ <dt><code>disks</code></dt>
+ <dd>On input, this is an optional listing of specific
+ instructions for disk checkpoints; it is needed when making a
+ checkpoint on only a subset of the disks associated with a
+ domain (in particular, since qemu checkpoints require qcow2
+ disks, this element may be needed on input for excluding guest
+ disks that are not in qcow2 format); if omitted on input, then
+ all disks participate in the checkpoint. On output, this is
+ fully populated to show the state of each disk in the
+ checkpoint. This element has a list of <code>disk</code>
+ sub-elements, describing anywhere from one to all of the disks
+ associated with the domain.
+ <dl>
+ <dt><code>disk</code></dt>
+ <dd>This sub-element describes the checkpoint properties of
+ a specific disk. The attribute <code>name</code> is
+ mandatory, and must match either the <code><target
+ dev='name'/></code> or an unambiguous
<code><source
+ file='name'/></code> of one of
+ the <a href="formatdomain.html#elementsDisks">disk
+ devices</a> specified for the domain at the time of the
+ checkpoint. The attribute <code>checkpoint</code> is
+ optional on input; possible values are <code>no</code>
+ when the disk does not participate in this checkpoint;
+ or <code>bitmap</code> if the disk will track all changes
+ since the creation of this checkpoint via a bitmap, in
+ which case another attribute <code>bitmap</code> will be
+ the name of the tracking bitmap (defaulting to the
+ checkpoint name).
+ </dd>
+ </dl>
+ </dd>
+ <dt><code>creationTime</code></dt>
+ <dd>The time this checkpoint was created. The time is specified
+ in seconds since the Epoch, UTC (i.e. Unix time). Readonly.
+ </dd>
+ <dt><code>parent</code></dt>
+ <dd>The parent of this checkpoint. If present, this element
+ contains exactly one child element, name. This specifies the
+ name of the parent checkpoint of this one, and is used to
+ represent trees of checkpoints. Readonly.
+ </dd>
+ <dt><code>domain</code></dt>
+ <dd>The inactive <a href="formatdomain.html">domain
+ configuration</a> at the time the checkpoint was created.
+ Readonly.
+ </dd>
+ </dl>
+
+ <h2><a id="BackupAttributes">Backup XML</a></h2>
+
+ <p>
+ Creating a backup, whether full or incremental, is done
+ via <code>virDomainBackupBegin()</code>, which takes an XML
+ description of the actions to perform. There are two general
+ modes for backups: a push mode (where the hypervisor writes out
+ the data to the destination file, which may be local or remote),
+ and a pull mode (where the hypervisor creates an NBD server that
+ a third-party client can then read as needed, and which requires
+ the use of temporary storage, typically local, until the backup
+ is complete).
+ </p>
+ <p>
+ The instructions for beginning a backup job are provided as
+ attributes and elements of the
+ top-level <code>domainbackup</code> element. This element
+ includes an optional attribute <code>mode</code> which can be
+ either "push" or "pull" (default push). Where elements are
+ optional on creation, <code>virDomainBackupGetXMLDesc()</code>
+ can be used to see the actual values selected (for example,
+ learning which port the NBD server is using in the pull model,
+ or what file names libvirt generated when none were supplied).
+ The following child elements are supported:
+ </p>
+ <dl>
+ <dt><code>incremental</code></dt>
+ <dd>Optional. If this element is present, it must name an
+ existing checkpoint of the domain, which will be used to make
+ this backup an incremental one (in the push model, only
+ changes since the checkpoint are written to the destination;
+ in the pull model, the NBD server uses the
+ NBD_OPT_SET_META_CONTEXT extension to advertise to the client
+ which portions of the export contain changes since the
+ checkpoint). If omitted, a full backup is performed.
+ </dd>
+ <dt><code>server</code></dt>
+ <dd>Present only for a pull mode backup. Contains the same
+ attributes as the <code>protocol</code> element of a disk
+ attached via NBD in the domain (such as transport, socket,
+ name, port, or tls), necessary to set up an NBD server that
+ exposes the content of each disk at the time the backup
+ started.
+ </dd>
+ <dt><code>disks</code></dt>
+ <dd>This is an optional listing of instructions for disks
+ participating in the backup (if omitted, all disks
+ participate, and libvirt attempts to generate filenames by
+ appending the current timestamp as a suffix). When provided on
+ input, disks omitted from the list do not participate in the
+ backup. On output, the list is present but contains only the
+ disks participating in the backup job. This element has a
+ list of <code>disk</code> sub-elements, describing anywhere
+ from one to all of the disks associated with the domain.
+ <dl>
+ <dt><code>disk</code></dt>
+ <dd>This sub-element describes the checkpoint properties of
+ a specific disk. The attribute <code>name</code> is
+ mandatory, and must match either the <code><target
+ dev='name'/></code> or an unambiguous
<code><source
+ file='name'/></code> of one of
+ the <a href="formatdomain.html#elementsDisks">disk
+ devices</a> specified for the domain at the time of the
+ checkpoint. The optional attribute <code>type</code> can
+ be <code>file</code>, <code>block</code>,
+ or <code>network</code>, similar to a disk declaration
+ for a domain, controls what additional sub-elements are
+ needed to describe the destination (such
+ as <code>protocol</code> for a network destination). In
+ push mode backups, the primary subelement
+ is <code>target</code>; in pull mode, the primary sublement
+ is <code>scratch</code>; but either way,
+ the primary sub-element describes the file name to be used
+ during the backup operation, similar to
+ the <code>source</code> sub-element of a domain disk. An
+ optional sublement <code>driver</code> can also be used to
+ specify a destination format different from qcow2.
