NAME

Sys::Virt::DomainCheckpoint - Represent & manage a libvirt guest domain checkpoint

DESCRIPTION

The Sys::Virt::DomainCheckpoint module represents a guest domain checkpoint managed by the virtual machine monitor.

METHODS

my $str = $domchkp->get_name()

Return the name of the checkpoint

my $xml = $domchkp->get_xml_description($flags)

Returns an XML document containing a complete description of the domain checkpoints' configuration. The $flags parameter accepts the following constants

Sys::Virt::DomainCheckpoint::XML_SECURE

Include security sensitive information in the XML dump, such as passwords.

Sys::Virt::DomainCheckpoint::XML_SIZE

Inlude dynamic per-<disk> size information

Sys::Virt::DomainCheckpoint::XML_NO_DOMAIN

Supress <domain> sub-element

$domchkp->delete($flags)

Deletes this checkpoint object & its data. The optional $flags parameter controls what should be deleted via the Sys::Virt::DomainCheckpoint::DELETE_* constants.

$parentchkp = $domchkp->get_parent();

Return the parent of the checkpoint, if any

my @checkpoints = $domchkp->list_all_children($flags)

Return a list of all domain checkpoints that are children of this checkpoint. The elements in the returned list are instances of the Sys::Virt::DomainCheckpoint class. The $flags parameter can be used to filter the list of return domain checkpoints.
