Remember to close the firewall on the test machine.
Cd/var/lib/tftpboot into the shared directory.
CP isolinux.cfg Pxelinux.cfg/default Copy the accepted files to Pxe.linux and rename them to default
Systemctl Restart Xinetd.service Restart daemon
vim/etc/dhcp/dhcpd.conf Edit the DHCP configuration file,
Subnet 172.25.254.0 netmask 255.255.255.0 {

} again
Systemctl Restart DHCPD
Test:
Set the NIC boot priority on a virtual machine
