14.15.2.2. Creating a snapshot for the current domain
The
virsh snapshot-create-as domain command creates a snapshot for the domain with the properties specified in the domain XML file (such as <name> and <description> elements). If these values are not included in the XML string, libvirt will choose a value. To create a snapshot run:
# virsh snapshot-create-as domain {[--print-xml] | [--no-metadata] [--reuse-external]} [name] [description] [--diskspec] diskspec]
The remaining options are as follows:
--print-xmlcreates appropriate XML forsnapshot-createas output, rather than actually creating a snapshot.--diskspecoption can be used to control how--disk-onlyand external checkpoints create external files. This option can occur multiple times, according to the number of <disk> elements in the domain XML. Each <diskspec> is in the form disk[,snapshot=type][,driver=type][,file=name]. To include a literal comma in disk or infile=name, escape it with a second comma. A literal--diskspecmust precede each diskspec unless all three of <domain>, <name>, and <description> are also present. For example, a diskspec ofvda,snapshot=external,file=/path/to,,newresults in the following XML:<disk name=’vda’ snapshot=’external’> <source file=’/path/to,new’/> </disk>
--reuse-externalcreates an external snapshot reusing an existing file as the destination (meaning this file is overwritten). If this destination does not exist, the snapshot request will be refused to avoid losing contents of the existing files.--no-metadatacreates snapshot data but any metadata is immediately discarded (that is, libvirt does not treat the snapshot as current, and cannot revert to the snapshot unless snapshot-create is later used to teach libvirt about the metadata again). This option is incompatible with--print-xml.
