Some of the required Perl modules are included in your Perl distribution.
Modules not included in your Perl distribution are available from CPAN
(www.cpan.org).See the "Install the Required Linux Packages & Perl Modules"
section of the online installation guide for how to use the provided script to
install the required Linux packages and Perl modules.
Management node system requirements:
- DHCP - VCL requires that a DHCP server, configured to listen on the private
network, be running on each management node.
Management node conditional system requirements:
- xCAT provisioning
In order to provision bare-metal or physical computers, xCAT must be installed
and properly configured. This release supports xCAT 2.x. Imaging support using
xCAT 2.x requires additional files. To enable imaging for xCAT 2.x, see the
page describing how to add support for partimage and partimage-ng in the
Apache VCL wiki.
- VMware vCenter provisioning
In order to provision virtual machines on VMware vCenter you will need the
vSphere SDK for Perl. This can be obtained from:
http://www.vmware.com/support/developer/viperltoolkit/
This is not required if provisioning virtual machines on standalone VMware ESX
or ESXi hosts.
- Windows XP & Windows Server 2003 bare-metal provisioning
The Sysprep utility is required to provision Windows XP and Windows Server
2003 bare-metal images. The utility can be downloaded from Microsoft. It is
included in newer versions of Windows. Sysprep is not required to provision
virtual machine images.
- Jabber notifications
VCL has the ability to send instant message notifications using Jabber. This
feature is optional and can be enabled or disabled by configuring the
"jabber=[yes|no]" property in the vcld.conf file. If the Jabber notification
feature is enabled, the Net::Jabber Perl module is required.
