Migration requires either that you have shared storage (both source and destination can see THE SAME FILE, and if one side sees the file via NFS, then both sides must see the file via NFS [you can't mix local and NFS]). OR, you have to tell migration that you want to migrate storage as well as machine state, by adding the --copy-storage-all flag to your command line. > The directory shown is where images are to be stored.
