virsh save-image-define file xml command will update the domain XML file that will be used when the specified file is later used during the
virsh restore command. The xml argument must be an XML file name containing the alternative XML with changes only in the host physical machine specific portions of the domain XML. For example, it can be used to account for the file naming differences resulting from creating disk snapshots of underlying storage after the guest was saved. The save image records if the domain should be restored to a running or paused state. Using the options
--paused dictates the state that is to be used.
