Virtualize within an already virtualized host, yes, why? who knows.
Here's what you will need:
A Mac running 10.5 (Leopard)
VMWare Fusion
Centos Install ISO
Ubuntu OpenVZ Image
Time
Coffee
Lack of sanity
Let's get to my crazy directions, which might or might not work :) (they did for me)
Vmware Fusion install of CentOS 5.2 using netinstall image (7.2MB :) )
HTTP Install with the following values
Web site Name: mirror.centos.org
CentOS Directory: centos/5.2/os/i386
Bare bone install, nothing extra
Gave Vmware Fusion 40GB Disk
Bridged Network
1 CPU
1024 RAM
Install vmware-tools
Installing OpenVZ
Grab YUM Repos
cd /etc/yum.repos.d
wget http://download.openvz.org/openvz.repo
rpm --import http://download.openvz.org/RPM-GPG-Key-OpenVZ
Install Kernel
yum install ovz-kernel-ent
Reboot and Select new kernel
chkconfig off un-needed services like cups/bluetooth etc
Disable firewall/SELinux
Add the following (this is only for IPv4)
vi /etc/sysctl.conf
net.ipv4.ip_forward = 1
net.ipv4.conf.all.rp_filter = 1
kernel.sysrq = 1
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0
Next install OpenVZ container mgmt and quotas
yum install vzctl vzquota
Start up OpenVZ
/sbin/service vz start
Next install packages needed for templates
yum install vzpkg vzyum vzrpm43-python vzrpm44-python vzctl-lib
Next change directory into
cd /var/lib/vz/template/cache
wget template of choice from here http://download.openvz.org/template/precreated/
I downloaded this http://download.openvz.org/template/precreated/ubuntu-8.04-x86.tar.gz
Lets create a container now. $IPADDR is a IP Address on your internal network.
vzctl create 101 --ostemplate ubuntu-8.04-x86
vzctl set 101 --onboot yes --save
vzctl set 101 --ipadd $IPADDR --save
vzctl set 101 --nameserver $IPADDROFDNS --save
vzctl set 101 --numothersock 120 --save
Increase DISKSPACE by default its a 1GB
vi /etc/vz/conf/101.conf
Turn off quota's if your just messing arould like me
vzquota off 101
Start up your container (OpenVZ speak for Guests in the VMware world)
vzctl start 101
Set root password
vzctl exec 101 passwd
SSH to IP Address you set
linux:~ jdunn$ ssh $IPADDR
jdunn@IPADDR's password:
Linux ubuntu-vps.joedunn.com 2.6.18-92.1.18.el5.028stab060.8ent #1 SMP Mon Feb 9 22:44:56 MSK 2009 i686

Now if your crazy and just want to mess around, lets install Gnome :)
sudo apt-get update
#Go grab a coffee when you run the next command
sudo apt-get install ubuntu-desktop
sudo /etc/init.d/gdm start
sudo apt-get install vnc4server xinetd
# Might need to set the display
DISPLAY=1.0
vi .vnc/xstartup and add gnome-session & instead of the default tdm
# Might need to break the lock on the Xauthority file
sudo xauth -b
#Lets Start up VNC
vncserver -name vzdesktop
#Now Lets Connect
on Leopard do the following
cmd + k
type: vnc://IPADDR:5901
Enjoy
#If you only want an application to run
ssh -Y $IPADDR
Application to run say 'firefox'
