The z/VM *MONITOR record device driver uses z/VM system services to provide
monitor data about z/VM guest operating systems to applications on Linux.
On Linux instances that run in environments other than the z/VM hypervisor,
the z/VM *MONITOR record device driver does not provide any useful
function and the corresponding monreader module cannot be loaded.
User response
Load the z/VM *MONITOR record device driver only on Linux instances that run
as guest operating systems of the z/VM hypervisor. If the z/VM *MONITOR
record device driver has been compiled into the kernel, ignore this message.
