• Install a dhcp server: 
    sudo dnf install -y dhcp-server
  • Edit the configurations of your DHCP server in /etc/dhcp/dhcpd.conf: 
    cat << "EOF" | sudo tee /etc/dhcp/dhcpd.conf
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.240 192.168.1.250;
option broadcast-address 192.168.1.255;
option routers 192.168.1.1;
filename "pxelinux.0";
next-server 192.168.1.71;
}

  • Install the tftp server: 
    sudo dnf install -y tftp-server
  • Start and enable the tftp service: 
    sudo systemctl enable --now tftp
  • Install the syslinux package, which contains the PXE bootloader: 
    sudo dnf install -y syslinux
  • Copy boot files to the TFTP server directory: 
    sudo cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
  • Create a directory for your installation files: 
    sudo mkdir /var/lib/tftpboot/<distro_name_here>
  • Mount the ISO image: 
    sudo mount -o loop /path/to/<your_ISO>.iso /mnt
  • Copy the contents of the distro ISO to the tftpboot directory: 
    sudo cp /mnt/images/pxeboot/{vmlinuz,initrd.img} /var/lib/tftpboot/<distro_name_here>
  • Create a configuration at /var/lib/tftpboot/pxelinux.cfg: 
    cat << "EOF" | sudo tee /var/lib/tftpboot/pxelinux.cfg

  • Restart the dhcp server: 
    sudo systemctl restart dhcpd
  • Restart the tftp server: 
    sudo systemctl restart tftp
  • Check that the configurations were correct: 
    sudo systemctl status dhcpd
sudo systemctl status tftp
  • Unmount the ISO at /mnt: 
    sudo umount /mnt
  • Edit this file on your host running libvirt: 
    /etc/libvirt/qemu.conf
  • Uncomment this line: 
    #vnc_listen = "0.0.0.0"
  • Restart libvirt with: 
    sudo systemctl restart libvirtd
  • Then for testing, set up a local VM with virt-install and in particular set the graphics option as vnc (default port is 5900): 
    virt-install --connect qemu:///system --name testvm --ram 4096 --vcpus 4 --network=bridge:virbr0 --pxe --osinfo detect=on,require=off --disk path=/home/howard/images/testvm.qcow2,size=20 --graphics vnc
  • Connect to the host that has the VM via its IP address and port 5900 like so: IP:PORT
