Chapter 7. Installing RHEL 6 on the cloner 107

4. Edit the duplicated profile by deleting the three LINK MAINT 040x lines, and inserting the

lines that are shown in bold text:

PROFILE LNXDFLT

IPL CMS

MACHINE ESA 10

CPU 00 BASE

CPU 01

CPU 02

CPU 03

CPU 04

CPU 05

SPOOL 000D 2540 PUNCH A

SPOOL 000E 1403 A

CONSOLE 009 3215 T

LINK MAINT 0190 0190 RR

LINK MAINT 019D 019D RR

LINK MAINT 019E 019E RR

LINK LNXMAINT 192 191 RR

LINK TCPMAINT 592 592 RR

Note that:

– The first line performs an IPL of CMS when the user ID is logged onto.

– You should update the MACHINE statement line to set the machine type to ESA with a

maximum number of CPUs that can be defined. In this example, the LPAR has

10 processors, so the value of the last parameter is set to 10.

– The next ten lines define ten virtual CPUs. Be sure to set the number of virtual CPUs

equal to (or less than) the number of physical CPUs.

– The NICDEF line defines a virtual NIC connected to the VSWITCH starting at virtual

address 600.

– The last two lines provide read access to the LNXMAINT 192 disk, as the user’s 191

disk, and the TCPMAINT 592 disk, so that the user has access to TCP/IP services,

such as FTP.

5. Go to the bottom of the file and add the definition for a new user ID named RH6CLONE.

This user ID is given class B, D, and E privilege classes, aside from the typical class G, to

run the FLASHCOPY command (B), the QUERY ALLOC MAP (D) command, and the

QUERY NSS (E) command. Be sure to replace the volume labels in bold and italics (for

example, UM6290) with the labels of your DASD:

USER RH6CLONE LNX4VM 512M 1G BDEG

INCLUDE LNXDFLT

Important: In the past, only two virtual CPUs were recommended for the next step. With

the new cpuplugd service (see 13.7, “Using the cpuplugd service” on page 224), this

recommendation has changed to be the same number as the physical CPUs. This setting

could have the side effect of allowing a single Linux virtual machine to consume a large

amount of CPU resource. You may consider leaving this setting at two for now.
