Virsh dumpxml

virsh dumpxml {guest-id, VM_MACHINE_NAME or uuid} [--inactive] [--security-info] [--update-cpu] [--migratable]

--migratable with --migratable one can request an XML that is suitable for migrations, i.e., compatible with older libvirt releases and possibly amended with internal run-time options. This option may automatically enable other options (--update-cpu, --security-info, ...) as necessary

virsh dumpxml MACHINE_NAME > /path/to/savefile.xml

virsh dumpxml —migrateable MACHINE_NAME > /path/to/savefile.xml
