24.2. Configuring DHCP for Diskless Clients

After configuring a tftp server, you need to set up a DHCP service on the same host machine. For instructions on setting up a DHCP server, see the Configuring a DHCP Server.
Enable PXE booting on the DHCP server by adding the following configuration to /etc/dhcp/dhcpd.conf:
```
allow booting;
allow bootp;
class "pxeclients" {
   match if substring(option vendor-class-identifier, 0, 9) = "PXEClient";
   next-server server-ip;
   filename "pxelinux.0";
}
```
- Replace server-ip with the IP address of the host machine on which the tftp and DHCP services reside.
Note
When libvirt virtual machines are used as the diskless client, libvirt provides the DHCP service and the stand alone DHCP server is not used. In this situation, network booting must be enabled with the bootp file='filename' option in the libvirt network configuration, virsh net-edit.

Now that tftp and DHCP are configured, configure NFS and the exported file system. For instructions, see the Section 24.3, “Configuring an Exported File System for Diskless Clients”.
