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.
