Reproduce with -13:

# virsh -c qemu+ssh://10.66.4.233/system vol-download foo.img /var/lib/libvirt/images/foo1.img --pool default
root.4.233's password: 
error: cannot receive data from volume foo.img
error: End of file while reading data: : Input/output error

Killed


Verified with -14, it's already fixed. Move this to VERIFIED.

# virsh -c qemu+ssh://10.66.4.233/system vol-download foo.img /var/lib/libvirt/images/foo1.img --pool default
