DISCLAIMER!

This document provides instuctions for configuring a standalone VCL environment running on a single computer which is able to provision VCL reservations using VMware.  It is only provided to help you understand how the various components of VCL operate.  This document DOES NOT describe how to configure a production VCL environment.  The environment described in this document can however be used to learn, test, and help develop VCL.

VMWare Server cannot be installed on a computer running a Xen kernel.  To determine if a Xen kernel is being used:

Panel
uname -a

The following output indicates a Xen kernel is being used:

Panel
Linux blade1g6-4 2.6.18-92.el5xen #1 SMP Tue Jun 10 19:20:18 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

If "xen" appears in the output of the previous command, replace the Xen Kernel with the following commands:

Panel
yum update ecryptfs-utils -y yum install kernel kernel-devel -y yum remove xen kernel-xen -y

Check the grub.conf file to make sure it is not configured to boot using the Xen Kernel

Panel
less /boot/grub/grub.conf

The grub.conf file should NOT look like this:

Panel

# grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE:  You have a /boot partition.  This means that #          all kernel and initrd paths are relative to /boot/, eg. #          root (hd0,0) #          kernel /vmlinuz-version ro root=/dev/sda3 #          initrd /initrd-version.img #boot=/dev/sda default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-92.el5xen)         root (hd0,0)         kernel /xen.gz-2.6.18-92.el5         module /vmlinuz-2.6.18-92.el5xen ro root=LABEL=/ pci=nommconf         module /initrd-2.6.18-92.el5xen.img

The grub.conf file SHOULD look like this:
