ESXi 6.7u2 NOTE: This guidance only supports network booting of the uefi installer for ESXi. The reason for this is the fog project does not ship iPXE kernels that support the comboot function. If you want to boot your ESXi server in legacy mode you will need to compile your own specific version of undionly.kpxe to add in the IMG_COMBOOT. First we’ll create the required directories: mkdir -p /images/os/esxi/6.7u2 Now we’ll mount the ESXi installer iso over the loop directory. Then we’ll copy the contents of the DVD to the directory we built above. mount -o loop -t iso9660 /{full path where you have the iso stored}/VMware-VMvisor-Installer-6.7.0.update02-13006603.x86_64.iso /mnt/loop cp -R /mnt/loop/* /images/os/esxi/6.7u2 umount /mnt/loop Edit the boot configuration file to use NFS to access all of ESXi’s files. # remove forward slashes from the config file sed -i 's/\///g' /images/os/esxi/6.7u2/efi/boot/boot.cfg Now we need to edit the/images/os/esxi/6.7u2/efi/boot/boot.cfg file to insert or modify the prefix parameter. Insert/modify the following line just below the title parameter. Also, be sure to replace {fog_server_ip} (exactly including the curly braces) with the actual IP address of your fog server. Your prefix line should look similar to this: prefix=nfs://192.168.1.20:/images/os/esxi/6.7u2 The last bit of magic we need to do is setup a new FOG iPXE boot menu entry for this OS. In the fog WebGUI go to FOG Configuration->iPXE New Menu Entry Set the following fields Menu Item: os.esxi67u2 Description: ESXi 6.7u2 Installer Parameters: kernel nfs://${fog-ip}:/images/os/esxi/6.7u2/efi/boot/bootx64.efi -c nfs://${fog-ip}:/images/os/esxi/6.7u2/efi/boot/boot.cfg boot || goto MENU Menu Show with: All Hosts That’s it, just pxe boot your target system and pick ESXi 6.7u2 Installer from the FOG iPXE boot menu. If for some reason you can not use NFS to pxe boot into the ESXi installer you can use tftp or http. If you want to use tftp extract the ESXi install files to /tftpboot/os/esxi/6.7u2. Then update the nfs:// protocols to tftp:// Be sure to remove the ':/images' after the host name or you will have errors. (i.e. kernel nfs://${fog-ip}:/images/os/esxi would become kernel tftp://${fog-ip}/os/esxi)
