Because the remote z/VM guest virtual machine is not authorized for IUCV

Add the statements 'IUCV ALLOW' and 'IUCV ANY' to the z/VM directory
entry of the remote z/VM guest virtual machine; then try again to
establish the connection. See "z/VM CP Planning and Administration"
for details about the IUCV statements.
