# README  : Contains summary about this CD
# Author  : Muhammad Kamran Azeem (kamran@wbitt.com)
# Created : 20110103
# Revision: 20110103
# Summary : This CD is CENTOS 5.5 x86_64 (64 bit), rebuilt by WBITT team, as Hypervisor Edition.
#################################################################################################
Detail:-
1) This is a bootable CD. (Of-course ;)
2) The CD contains four groups only: 
* core [Not visible in installer.]
* base
* xen (Named/shown as group: Virtualization)
* kvm (Named/shown as group: KVM)

3) These groups can be used in your kickstart files.
4) The groups are designed in such a way, that if you do not select any group (uncheck all of them at the time of installation), 
you will get a minimal installation, containing yum and wget. In minimal install you won't get any protection. 
5) SELINUX and IPTABLES are not installed in the minimal (@core) installation.
all other packages if needed must be copied, or installed from the CD directly.
Or whatever way you prefer, including, but not limiting to using YUM.
6) The base contains xterm. If you select that, xterm and its (minimal) necessary X packages will also get installed automatically. (Vesa drivers)
7) If you decide to use kickstart, then please note, that the software in this CD is (should be) compatible with your current kickstarts.
8) The complete CD can be copied to an NFS/HTTP/FTP server, and can in-turn be used for network based installations, of the same.
9) The CD has both KVM and XEN hypervisors. Includes kernel-xen. 
10) If you select the category "Virtualization" at the install time, and do not check "customize software selection", XEN will be installed.
