Using the "mach" program you can easily create a minimal template for virtually any Red Hat OS. The following example creates a template for Centos 5.2 i386.
# Install mach on the host node or your build server
#: yum install mach
# Edit /etc/mach/conf to use the OS version / architecture you want
# Setup the chroot
#: mach setup base
# Setup any additional packages you want in the chroot
#: mach yum install yum
edit /etc/mach/conf to use the centos i386 extras template
run mach setup base
mach yum install yum vim-minimal passwd ssh-clients openssh-server
# Run the script below in the chroot directory (/var/lib/mach/roots/template-name)
# Package the template into /vz/template/cache
#: cd /var/lib/mach/roots/template-name
#: tar czf /vz/template/cache/template-name.tar.gz .
# At this point I create a "template" VE and do any other additional configuration inside the running VE, verify that it works, etc. Then I repackage it again.
''Script to turn mach chroot into vz template:''
Run these commands from /var/lib/mach/root/template. Replace the ROOT_PWD_HASH with your root password hash with your own hash if you want to set the password for the template. (otherwise, you can vzctl enter VEID and change the password).
