NAME

       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 $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.

       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
