23.10 Setting up the DHCP server for virtual guests

HP recommends that you map (for the

DHCP

server) the MAC addresses to the IP addresses,

particularly if you want to monitor the virtual machine guests (

virtual guest

s). Here, within the /etc/

dhcpd.conf

file, is a map for virtual machines vm001 and vm002, which are used as an example.

group {
option subnet-mask 255.255.252.0;
option routers 192.0.2.1;
option domain-name-servers 192.0.2.51,192.0.2.52;
option ntp-servers ntp1.example.com,ntp2.example.com;
option domain-name "example.com";

host vm001 {
hardware ethernet 00:16:3E:AB:CD:01;
fixed-address 192.0.2.150;
option host-name "vm001";
}

host vm002 {
hardware ethernet 00:16:3E:AB:CD:02;
fixed-address 192.0.2.151;
option host-name "vm002";
}
}

MAC addresses for some Xen virtual machines begin with the octets 00:16:3E; the final three
octets are chosen arbitrarily.

Likewise, MAC addresses for some KVM virtual machines begin with the octets 52:54:00; the
final three octets are also chosen arbitrarily.

A convention used in this map is that the value of the last two (hexadecimal) digits of the MAC
address matches the (decimal) value of the host name. For example, a host named vm011, would
correlate to a MAC address ending with the octet 0B.

23.11 Uninstalling atftp and installing tftp

1.

1. Log in as root on the CMS.

2.

Use the rpm command to erase atftp:

# rpm -e atftp

3.

Use the rpm command to install tftp, for example:

# rpm -Uvh tftp-0.48-1.6.x86_64.rpm

4.

Edit the /etc/xinetd.d/tftp file as follows:
a.

Change the following to enable tftp:

disable = no

b.

Set the path:

server_args = -s /opt/repository/boot

c.

Save the file and exit.

5.

Restart the xinetd service:
