In some cases management application needs to allocate memory for qemu upfront and then just let qemu use that. Since we don't want to expose path for memory-backend-file anywhere in the domain XML, we can generate predictable paths. In this case: $memoryBackingDir/libvirt/qemu/$shortName/$alias where $shortName is result of virDomainDefGetShortName().
