Since fec8f9c49af we try to use predictable file names for 'memory-backend-file' objects. But that made us provide full path to qemu when hot plugging the object while previously we provided merely a directory. But this makes qemu behave differently. If qemu sees a path terminated with a directory it calls mkstemp() and unlinks the file immediately. But if it sees full path it just calls open(path, O_CREAT ..); and never unlinks the file. Therefore it's up to libvirt to unlink the file and not leave it behind.

Zack, can you please check if this patch is suitable for your use cases?
