Before diving right into the installation of FOG you need to decide which server OS you are going to use. FOG is made to install on RedHat based distro CentOS, Fedora, RHEL amongst others as well as Debian, Ubuntu and Arch Linux. Choose whichever you like most and have knowledge about! FOG is known to work with any of the above noted systems. Installation manuals are available for most current releases.

This listing is for informational purposes only, as the required components will be automatically downloaded and installed by the FOG installation script: PHP 5/6/7, MySql 5+, Apache 2+, DHCP (any!), TFTP, FTP, NFS

The LAMP setup can also be easily adjusted for a "WAMP (Windows Apache MySQL PHP) system" though will require a bit more knowledge of what packages to use and how to integrate with the FOG system.

Getting FOG

svn git, tar.gz

Debian Wheezy, Debian Squeeze, Debian Lenny


Fedora 23 Server, Fedora 21 Server, Fedora 14, Fedora 13, Fedora 11, Fedora 10, Fedora 9, Fedora 8, Fedora 7




Ubuntu 14.10 (Buggy), Ubuntu 14.04, Ubuntu 13.10, Ubuntu 13.04, Ubuntu 12.10, Ubuntu 12.04, Ubuntu 11.04, Ubuntu 10.10, Ubuntu 10.04, Ubuntu 9.04, Ubuntu 8.10, Ubuntu 8.04, Ubuntu 7.10


FOG can be used on bare metal as well as in most virtual server and client setups. Some of the virtualization techniques are really great when used with FOG, e.g. snapshots. Some people use virtualization to prepare and upload their "golden (master) images" all on one central location/server. Again like with the server OS we don't prefer any of the following or others that are out there. This is only a collection of hints and tricks plus maybe issues we know about.


Using the New VM Wizard:

Ensure the virtual switch your VM is connected to has a route to FOG!

Create VM Wizard > Installation Options: Select "Install an operating system from network-based installation server"

Existing VM:

Ensure the virtual switch your VM is connected to has a route to FOG!

Right click VM > Settings > BIOS

Move "Network Adapter" (sometimes labeled "Legacy Network Adapter") to the top of the boot order.


UEFI/Secure Boot is an option with Hyper-V on Server 2012 on Generation 2 VMs. It is enabled by default, and can be disabled in VM Settings -> Firmware: Uncheck secure boot.

Can be used as kind of a lightweight desktop virtual environment to test FOG and master your images. Using this on the laptop as local test environment. Search forums and wiki but there is no valuable information about anyone using FOG on a KVM server. Asked user mxc as he seams to use it. Otherwise this will be a brief description on how to use this as I do it.

# setup network tap device as kind of a local software switch to connect it all
sudo tunctl -t tap0 -u <username>
sudo ifconfig tap0 x.x.x.x netmask up
# generate disk image file
qemu-img create -f qcow2 hd.qcow2 10G
# start VM using QEMU emulator (BIOS mode)
qemu -m 512 -boot n -net nic,vlan=1 -net tap,vlan=1,ifname=tap0,script=/bin/true -hda hd.qcow2
# start VM using real KVM virtualization (BIOS mode)
kvm -m 512 -boot n -net nic,vlan=1,macaddr=00:00:00:00:00:05 -net tap,vlan=1,ifname=tap0,script=/bin/true -hda hd.qcow2
# start VM as UEFI machine - as well using the more modern '-netdev' parameter
kvm -m 512 -boot n -bios /usr/share/ovmf/OVMF.fd -device virtio-net-pci,netdev=hn0 -netdev tap,id=hn0,ifname=tap0,script=/bin/true -hda hd.qcow2


OpenVZ (possibly within Proxmox) is mostly used to run the FOG server in a light weight kind of virtual environment. As OpenVZ is in nature similar to a chrooted environment you cannot actually PXE boot such a container. To install FOG as a server in OpenVZ you need to have NFS support on the host machine first and then add it to the container as well:

$ lsmod | grep nfsd
nfsd                  312315  14
$ grep nfsd /proc/filesystems
nodev   nfsd

If you don't see the kernel module nfsd loaded you might need to install the nfs-kernel-server package and load the module (usually done by the nfs-kernel-server init script). As mentioned before you need to enable access to nfsd from within the container you want to install FOG to:

$ vzctl stop $CONTAINER_ID
$ vzctl set $CONTAINER_ID --feature  nfsd:on --save
$ vzctl start $CONTAINER_ID

After that the installer should run through like it would installing on bare metal or any other virtual environment!


Bridged network, host only. Older versions have (PXE?) bug - Tom knows about that.


Running a FOG client within an ESXi server is pretty close to what you would do on a bare metal machine:

  • Create VM as normal.
  • Open VM Console, start up the VM. Press F2 on Boot Logo to enter BIOS.
  • Scroll over to boot tab, use + key to move Network boot to the top of the boot order.

You can also do an on-demand network boot by hitting F9 on startup, if you don’t want to change the boot order permanently.


UEFI is disabled by default for VMs in ESXI 6.0+. To enable it for a VM, go to VM Settings > Options Tab > Advanced: Boot Options and change the boot firmware from BIOS to EFI.

VMWare Player

Is this still in use?? Don't care if there is nothing about it in wiki or forums!


See forums


Firewalld iptables SELinux


IMPORTANT, what to do when the installer fails? Where are the logs?
