Hi,
there is no virtual environment I am aware of that works with AIX these days ... but a nice 43p 150 or a B50 or B80 should be affordable these days - and is enough to teach you the very basic administration of AIX.
But knowing how to extend filesystems or delete a user on AIX doesn't make you a system administrator ... AIX is these days so highly virtualized that you will hardly be able to teach yourself all the skills required to work as a system administrator in a mid-to-large size company with current technology with external storage, clustering, TSM backups, Tivoli monitoring and all the fun stuff. So I would highly recommed to get some formal training in the more complex areas like virtualization before you go for a job as a system administrator.
In addition you should have a solid background of other areas in IT like networking, maybe some hardware- and shell scripting skills - and the ability to live for days without food or sleep in case of tough production issues... So if you want to have a life or any further commitments (wife, children, personal interests) - don't take a job in a smaller company - be aware that being a sysadmin is in many cases a 24/7/365 commitment, a permanent challenge - but the greates job you can get - I can promise you it will never be boring at all.
Kind regards

appconfig::sys
AppConfig::Sys(3) User Contributed Perl Documentation AppConfig::Sys(3)
NAME
AppConfig::Sys - Perl5 module defining platform-specific information and methods for other AppConfig::* modules.
SYNOPSIS
use AppConfig::Sys;
my $sys = AppConfig::Sys->new();
@fields = $sys->getpwuid($userid);
@fields = $sys->getpwnam($username);
OVERVIEW
AppConfig::Sys is a Perl5 module provides platform-specific information and operations as required by other AppConfig::* modules.
AppConfig::Sys is distributed as part of the AppConfig bundle.
DESCRIPTION
USING THE AppConfig::Sys MODULE
To import and use the AppConfig::Sys module the following line should appear in your Perl script:
use AppConfig::Sys;
AppConfig::Sys is implemented using object-oriented methods. A new AppConfig::Sys object is created and initialised using the
AppConfig::Sys->new() method. This returns a reference to a new AppConfig::Sys object.
my $sys = AppConfig::Sys->new();
This will attempt to detect your operating system and create a reference to a new AppConfig::Sys object that is applicable to your
platform. You may explicitly specify an operating system name to override this automatic detection:
$unix_sys = AppConfig::Sys->new("Unix");
Alternatively, the package variable $AppConfig::Sys::OS can be set to an operating system name. The valid operating system names are:
Win32, VMS, Mac, OS2 and Unix. They are not case-specific.
AppConfig::Sys METHODS
AppConfig::Sys defines the following methods:
getpwnam()
Calls the system function getpwnam() if available and returns the result. Returns undef if not available. The can_getpwnam() method
can be called to determine if this function is available.
getpwuid()
Calls the system function getpwuid() if available and returns the result. Returns undef if not available. The can_getpwuid() method
can be called to determine if this function is available.
