Sys::Virt::DomainCheckpoint(3)

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
        Include dynamic per-<disk> size information

    Sys::Virt::DomainCheckpoint::XML_NO_DOMAIN
        Suppress <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.

Sys::Virt::DomainCheckpoint::LIST_DESCENDANTS
    Only list checkpoints which are descendants of the current checkpoint

Sys::Virt::DomainCheckpoint::LIST_LEAVES
    Only list leaf nodes in the checkpoint tree

Sys::Virt::DomainCheckpoint::LIST_NO_LEAVES
    Only list non-leaf nodes in the checkpoint tree

Sys::Virt::DomainCheckpoint::LIST_TOPOLOGICAL
    Sort list in topological order w.r.t. to parent/child relationships.
