Sys::Virt::DomainSnapshot - Represent & manage a libvirt guest domain DESCRIPTION
The "Sys::Virt::DomainSnapshot" module represents a guest domain managed by the virtual machine monitor. METHODS
my $str = $domss->get_name() Return the name of the snapshot my $xml = $domss->get_xml_description($flags) Returns an XML document containing a complete description of the domain's configuration. $domss->delete($flags) Deletes this snapshot object & its data. The optional $flags parameter controls what should be deleted via the "Sys::Virt::DomainSnapshot::DELETE_*" constants. $domss->revert_to($flags) Revert the domain to the state associated with this snapshot. The optional $flags control the state of the vm after the revert via the "Sys::Virt::DomainSnapshot::REVERT_*" constants. $parentss = $domss->get_parent(); Return the parent of the snapshot, if any $count = $domss->num_of_child_snapshots() Return the number of saved snapshots which are children of this snapshot @names = $domss->list_child_snapshot_names() List the names of all saved snapshots which are children of this snapshot . The names can be used with the "lookup_snapshot_by_name" @snapshots = $domss->list_child_snapshots() Return a list of all snapshots that are children of this snapshot. The elements in the returned list are instances of the Sys::Virt::DomainSnapshot class. CONSTANTS
SNAPSHOT CREATION The following constants are useful when creating snapshots Sys::Virt::DomainSnapshot::CREATE_CURRENT Set the defined snapshot to be the current snapshot Sys::Virt::DomainSnapshot::CREATE_DISK_ONLY Only snapshot the disk, not the memory state Sys::Virt::DomainSnapshot::CREATE_HALT Stop the guest after creating the snapshot Sys::Virt::DomainSnapshot::CREATE_NO_METADATA Do not save any metadata for the snapshot Sys::Virt::DomainSnapshot::CREATE_REDEFINE Replace/set the metadata with the snapshot Sys::Virt::DomainSnapshot::CREATE_QUIESCE Quiesce the guest disks while taking the snapshot Sys::Virt::DomainSnapshot::CREATE_REUSE_EXT Reuse the existing snapshot data files (if any) Sys::Virt::DomainSnapshot::CREATE_ATOMIC Create multiple disk snapshots atomically SNAPSHOT DELETION The following constants are useful when deleting snapshots Sys::Virt::DomainSnapshot::DELETE_CHILDREN Recursively delete any child snapshots Sys::Virt::DomainSnapshot::DELETE_CHILDREN_ONLY Only delete the child snapshots Sys::Virt::DomainSnapshot::DELETE_METADATA_ONLY Only delete the snapshot metadata SNAPSHOT LIST The following constants are useful when listing snapshots Sys::Virt::DomainSnapshot::LIST_METADATA Only list snapshots which have metadata Sys::Virt::DomainSnapshot::LIST_ROOTS Only list snapshots which are root nodes in the tree Sys::Virt::DomainSnapshot::LIST_DESCENDANTS Only list snapshots which are descendants of the current snapshot Sys::Virt::DomainSnapshot::LIST_LEAVES Only list leave nodes in the snapshot tree SNAPSHOT REVERT The following constants are useful when reverting snapshots Sys::Virt::DomainSnapshot::REVERT_PAUSED Leave the guest CPUs paused after reverting to the snapshot state Sys::Virt::DomainSnapshot::REVERT_RUNNING Start the guest CPUs after reverting to the snapshot state Sys::Virt::DomainSnapshot::REVERT_FORCE Force the snapshot to revert, even if it is risky to do so AUTHORS
