By default, home directories on the POWER system are escaped from x86World during the

installation process. All user home directories are then visible to both x86 and POWER applications.

You can optionally set the home directory to not escape if you prefer.

Remote file systems

Non-local file systems can be made accessible from the VxE. This is done by mounting the file system

on the POWER side. You then mount the remote file system directly to a mountpoint within

x86World, or to a mountpoint external to x86World, and then you use the linkx86 command from the

POWER side to create an escape to the mountpoint. Note that you can only use the linkx86 command

to create an escape on the POWER side, and not the x86 side.

x86 configuration and daemons

It might be necessary to migrate x86 daemons onto the POWER system. They can be automatically

started in a VxE on the host system by inserting a suitable script in the X86WORLD_ROOT/etc/init.d

directory and setting up symbolic links to it in X86WORLD_ROOT/etc/rc{2-5}.d. You can use the

tools provided by the supported distribution to perform this configuration (chkconfig or YAST). The

PowerVM Lx86 startup script runs scripts in this directory when the system boots according to the

current runlevel of the POWER distribution. For example, if the current runlevel on the POWER

distribution is 3, the x86 distribution will start the x86 services configured for runlevel 3. By default,

on runlevels 2, 3, 4, and 5 the standard installation only starts syslogd. For more information about

the PowerVM Lx86 startup script, see Chapter 5, “Running the PowerVM Lx86 installation script,” on

page 19.

Environment variables

Environment variables set from within an x86 shell apply only to that shell. If more than one x86 shell

is open on a system, then the environment variables are completely independent of each other.

Installing x86 applications

This procedure describes how to install x86 applications onto a POWER system.

Installing an x86 application onto a POWER system is the next step after you install PowerVM Lx86 and

configure the system. Installing x86 applications consists of the following tasks:

• Install, copy, or set access to the x86 application binaries.

• Transfer data, or set access to application data.

• Create access to required devices, such as remote file systems.

Install, copy, or set access to the x86 application binaries

The x86 application binaries must be either installed in x86World, or made accessible from x86World.

To install binaries into x86World, you can copy them directly into x86World (or to a location accessible from

x86World through an escape or a mount point). If x86 application installation scripts or packages exist, then
