4.6 Spool contents
z/VM can emulate card reader, line printer, and card punches for users. While the equivalent
“real” devices are no longer used, these virtual devices can be useful. In general, simple
usage of z/VM as a base for running multiple z/OS guests will not involve these devices.
However, various internal z/VM services (such as TCP/IP) write logs to the virtual printer or
send messages and logs as input to the virtual card reader. You may want to review this
information. In the fullness of time (probably a long time), these could fill the spool space
provided with the distributed z/VM 6.2 system.
