|
|
|
|
<p>
|
|
Attributes of libvirt snapshots are stored as child elements of
|
|
the <code>domainsnapshot</code> element. At snapshot creation
|
|
time, only the <code>name</code> and <code>description</code>
|
|
elements are settable; the rest of the fields are informational
|
|
(and readonly) and will be filled in by libvirt when the
|
|
snapshot is created.
|
|
</p>
|
|
<p>
|
|
The top-level <code>domainsnapshot</code> element may contain
|
|
the following elements:
|
|
</p>
|
|
<dl>
|
|
<dt><code>name</code></dt>
|
|
<dd>The name for this snapshot. If the name is specified when
|
|
initially creating the snapshot, then the snapshot will have
|
|
that particular name. If the name is omitted when initially
|
|
creating the snapshot, then libvirt will make up a name for the snapshot.
|
|
</dd>
|
|
<dt><code>description</code></dt>
|
|
<dd>A human-readable description of the snapshot. If the
|
|
description is omitted when initially creating the snapshot,
|
|
then this field will be empty.
|
|
</dd>
|
|
<dt><code>creationTime</code></dt>
|
|
<dd>The time this snapshot was created. The time is specified
|
|
in seconds since the Epoch, UTC (i.e. Unix time). Readonly.
|
|
</dd>
|
|
<dt><code>state</code></dt>
|
|
<dd>The state of the domain at the time this snapshot was
|
|
taken. When the domain is reverted to this snapshot, the domain's state
|
|
will be set to whatever is in this field. Readonly.
|
|
</dd>
|
|
<dt><code>parent</code></dt>
|
|
<dd>The parent of this snapshot. This element contains exactly
|
|
one child element, name. This specifies the name of the parent
|
|
snapshot of this snapshot, and is used to represent trees of
|
|
snapshots. Readonly.
|
|
</dd>
|
|
<dt><code>domain</code></dt>
|
|
<dd>The domain that this snapshot was taken against. This
|
|
element contains exactly one child element, uuid. This
|
|
specifies the uuid of the domain that this snapshot was taken
|
|
against. Readonly.
|
|
</dd>
|

</dl>
