Install custom Operating Systems on

OVH has a budget offering called So you start. If you want to install an operating system, that is not covered by the automatic installation, or want to encrypt your server, or install Linux with ZFS on root, you can't use the provided installation mechanism. You can order a KVM over IP for additional costs to do the installation, or you can follow the following steps, to run the installation under Qemu/KVM. I took them from this forum entry, if you want to know more about it then click to read more:

Now that we have kvm installed, we can get for example an Ubuntu 14.04 Image and do the installation from there.

Now we start kvm with vnc support and do the installation from there:

The VNC Server will listen on localhost only, so that no one else can access it. You need to tunnel yourself with SSH through.

This is also helpful to start your server under KVM, to fix any boot issues you might have.

  1. Thanks a lot for this simplified tutorial on installing your own ISO on a SoYouStart server!

    I just would like to add for anybody else that has gone through the same pain as me:

    If you have already an OS installed on your server, you will need to wipe out your hard drives. I found the useful information on the thread that this tutorial is based on.

    #CAREFULL Wipe hard disks, so that you can start your OS installation, remove “#” to execute
    #dd if=/dev/zero of=/dev/sda bs=1M count=1
    #dd if=/dev/zero of=/dev/sdb bs=1M count=1

    Also, for anyone trying to figure out how to use the vnc, I used:
    vncviewer -geometry 1024×768 -via root@myIPaddress localhost:0

    Cheers 😉

  2. One of my disks never shows up during my install.. suggestions?

    • If you are using a third disk, you will need to tweak the last command in the tut.


      add hdc as /dev/sdc

      qemu-system-x86_64 -net nic -net user,hostfwd=tcp::80-:80 -m 2047M -alt-grab -localtime -enable-kvm -cpu kvm64,+nx -smp 2 -usbdevice tablet -k en-us -cdrom ubuntu-14.04.1-desktop-amd64.iso -hda /dev/sda -hdb /dev/sdb -hdc /dev/sdc -vnc

      Hope it helps

  3. Just wanted to add that REALVNC doesn’t work but TigerVNC does (on mac osx)
