A SUSE Linux Enterprise Server installation needs at least two devices: a DASD and a network connection device. For an IPL from tape, a tape device should also be accessible. Devices are configured and attached to an LPAR in the IOCDS (input output configuration data set). This example defines one DASD, one OSA-2 network device, and a tape device for LPAR Z1. For further information about how to set up the IOCDS for Linux, refer to IBM hardware documentation of your machine .

CHPID PATH=FD,TYPE=DSD,PART=(Z1) 
CHPID PATH=FE,TYPE=OSA,PART=(Z1) 
CHPID PATH=10,TYPE=CNC,PART=(Z1)

CNTLUNIT CUNUMBR=FD00,PATH=FD,UNITADD=((00,1)),UNIT=3990-2 
IODEVICE ADDRESS=(FD00,1),CUNUMBR=FD00,UNIT=3390

CNTLUNIT CUNUMBR=FE20,PATH=FE,UNIT=OSA,UNITADD=((20,1)) 
IODEVICE ADDRESS=(FE20,1),CUNUMBR=FE20,UNIT=OSA,PART=Z1

CNTLUNIT CUNUMBR=100A,PATH=10,UNIT=3480,UNITADD=((0A,1)) 
IODEVICE ADDRESS=100A,CUNUMBR=100A,UNIT=3480,PART=Z1

Proceed with Section 2.4.1, “LPAR Installation”.

The first step is to attach and format one or multiple DASDs in the system to be used by the Linux guest in z/VM. Next, create a new user in z/VM. The example shows the directory for a user LINUX1 with the password LINPWD, 256 MB of memory (extendable up to 1024 MB), 32 MB of expanded RAM (XSTORE), some minidisks (MDISK), two CPUs and an OSA QDIO device.

	Assigning Memory to z/VM guests
When assigning memory to a z/VM guest, make sure that the memory size suits the needs of your preferred installation type. See Section 1.1.1.1, “Memory Requirements”. To set the memory size to 512 MB, use the command CP DEFINE STORAGE 512M. After the installation has finished, reset the memory size to the desired value.

MDISK 151 3390 0253 2800 DASD40 MR ONE4ME TWO4ME THR4ME

This example uses minidisk 201 as the guest's home disk. Minidisk 150 with 200 cylinders is the Linux swap device. Disk 151 with 2800 cylinders holds the Linux installation.

Now add (as the user MAINT) the guest to the user directory with DIRM FOR LINUX1 ADD. Enter the name of the guest (LINUX1) and press F5. Set up the environment of the user with:

DIRM DIRECT 
DIRM USER WITHPASS

The last command returns a reader file number. This number is needed for the next command:

RECEIVE <number> USER DIRECT A (REPL)

Assign the directories to the guest with DISKMAP USER DIRECT A. You can now log in on the guest as user LINUX1.

If you do not have the dirmaint option available, refer to the IBM documentation to set up this user.

Proceed with Section 2.4.2, “z/VM Installation”.
