The following script will install PXE Boot server. Change the variables to your environment.
- SERVER_IPADDR is IP adress of PXE Boot server.
- DHCP_SERVER_INTERFACESv4 is network interface name for DHCP. DHCP will be provided via this network interface.
- DHCP_SUBNET is network address for DHCP.
- DHCP_NETMASK is subnet for DHCP.
- DHCP_DNS is DNS for DHCP.
- DHCP_ROUTER is gateway for DHCP.
- DHCP_CLIENT_HOSTNAME is hostname of client.
- DHCP_CLIENT_IPADDR is IP address of client.
- DHCP_CLIENT_MACADDR is MAC address of client.
NFS root filesystem is set to the following.
- Set root user password to “fedora”.
- Create user which name is “fedora” and password is “fedora”.

2 Run Fedora 26 thin client with NFS
This article runs Fedora 26 thin client on virtual machine on KVM. Virtual machine on VirtualBox and real machine too can run Fedora 26 thin client with enabling network boot. Please check your BIOS setting.
Enable “NIC” of “Boot device order” and make it top of order with virt-manager.
iPXE sends DHCP requests, receives DHCP response from PXE Boot server, download and run boot image.
syslinux’s menu is displayed. After 1 second, “Fedora 26 thin client” will be selected automatically.
Fedora 26 thin client is started.
Login is displayed.
