environment as well as run some REXX
™
EXECs (script-like executable files) to
set up Linux. After changing the environment, you can load Linux into the
virtual machine.
3.
The MACHINE statement describes the processor architecture of the virtual
machine. The maximum number of virtual CPUs that can be defined for this
virtual machine is four. The default is one.
4. The CONSOLE statement defines the operating console ( virtual console ) for the
virtual machine. CMS requires console type 3215. If supported by the operating
system, you can specify 3270 or issue the CP command TERMINAL CONSOLE
3270 in the PROFILE EXEC prior to loading the operating system.
5. The NICDEF statement defines this virtual machine’s attachment to a z/VM
virtual switch.
6.
SPOOL statements define the unit record devices. By convention, device
number 000C is for the virtual reader (type 3505), device number 000D is for
the virtual punch (type 3525), and device number 000E is for the virtual printer
(type 1403).
7. LINK statements provide access to another virtual machine’s minidisks.
8. MDISK statements define minidisks owned by the virtual machine. The format
of the statement is:
MDISK devno type start_cyl extent vol_label access_mode
where
devno
Is the virtual device number of the minidisk.
type
Is the disk type of the real disk; typically 3390.
start_cyl
Is the real disk starting location of the first cylinder of the minidisk.
extent
Is the minidisk size in cylinders.
vol_label
Is the volume label of the real disk.
access_mode
Is the access mode. MR means the virtual machine has read/write access.

Overview of the Conversational Monitor System (CMS)
Just as you can interact with Linux or UNIX
®
through a bash or Korn shell, you
can interact with z/VM through CMS. Like a shell, you can use CMS to edit files,
run EXECs (script-like executable files) or programs, modify the virtual machine
environment, or modify z/VM itself. CMS is to z/VM as a shell is to Linux or
UNIX.
Minidisks and the CMS access mode
CMS, like other operating systems running in a virtual machine, can access
minidisks to store and retrieve files. For CMS, each minidisk has an
access mode
