vmur.53bf56 The <z/VM virtual unit record device driver> cannot be loaded without z/VM
Explanation
The z/VM virtual unit record device driver provides Linux with access to
z/VM virtual unit record devices like punch card readers, card punches, and
line printers. On Linux instances that run in environments other than the
z/VM hypervisor, the device driver does not provide any useful function and
the corresponding vmur module cannot be loaded.
User response
Load the vmur module only on Linux instances that run as guest operating
systems of the z/VM hypervisor. If the z/VM virtual unit record device
has been compiled into the kernel, ignore this message.
