• Change state of localvmhost to vmhostinuse (edit the database directly, do not use the Virtual Hosts utility on the website)
• Assign vm guests to localvmhost
• Create node in priviledge tree

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

...

Install the VMware Server RPM:

...

Verify the host-only network was configured correctly:

...

Modify the /etc/hosts file to include entries for the VM host and guest computers:

Configure the sshd Service to Listen on the Virtual Private Network 

...

Add the VM host's public key to its own authorized_keys file to allow it to SSH to itself without a password prompt: 

...

Configure the vcld.conf file to use vcl.key:

...

Save a copy of the original dhcpd.conf file:

ddns-update-style none;
shared-network vmnet1 {
        subnet 192.168.0.0 netmask 255.255.0.0 {
                ignore unknown-clients;
                option routers 192.168.0.1;                host vmguest-1 {
                        option host-name "vmguest-1";
                        hardware ethernet 00:50:56:1a:01:01;
                        fixed-address 192.168.1.1;
                        filename "/tftpboot/pxelinux.0";
                        option dhcp-server-identifier 192.168.0.1;
                        next-server 192.168.0.1;
                }
        }
}

The DHCP daemon should only listen on the virtual private network (vmnet1) to avoid conflicts with other production VCL networks.  Configure the dhcpd service startup script to only listen on the vmnet1 interface:

start() {
    [ -x $dhcpd ] || return 5
    [ -f $conf ] || return 6

    pidofproc $prog >/dev/null 2>&1
    RETVAL=$?
    [ $RETVAL -eq 0 ] && return $RETVAL

    echo -n $"Starting $prog: "
    daemon $dhcpd vmnet1 $DHCPDARGS 2>/dev/null
    RETVAL=$?
    echo
    [ $RETVAL = 0 ] && touch $lockfile
    return $RETVAL
}

Configure the dhcpd service to automatically start at runlevels 3-5:
