Building a CentOS 6.4 vmfest model

1. Retrieve ISO. I used http://www.gtlib.gatech.edu/pub/centos/6.4/isos/x86_64/CentOS-6.4-x86_64-minimal.iso.

2. Create new VBox guest

   • Pick Red Hat (64 bit) as the OS type.
   • Configure the first network adapter as host-only vboxnet0, and a second as NAT.
   • Attach the VBoxGuestAdditions.iso (for Debian host it's available in /usr/share/virtualbox).

3. Run through the installer. Defaults are fine here.

4. Reboot. Log in as root.

5. Create the vmfest user and add to sudoers

   • adduser vmfest; passwd vmfest
   • visudo

6. Create the ethernet interface definitions:

    # cat <<EOF >/etc/sysconfig/networking/devices/ifcfg-eth0
    DEVICE=eth0
    TYPE=Ethernet
    ONBOOT=yes
    BOOTPROTO=dhcp
    EOF
    # cat <<EOF >/etc/sysconfig/networking/devices/ifcfg-eth1
    DEVICE=eth1
    TYPE=Ethernet
    ONBOOT=yes
    BOOTPROTO=dhcp
    EOF
   

7. Reboot. Log in as root.

8. sudo yum update

9. Install packages for guest addition compile

    sudo yum install -y \
       make gcc kernel-devel perl \
       xorg-x11-server-Xorg.x86_64
   

10. Mount and install guest additions

    mount /dev/scd0 /media; cd /media
    ./VBoxLinuxAdditions.run
    

11. Reboot again for good measure and customize further or install more packages.

12. DO NOT FORGET THIS STEP AND DO NOT REBOOT AFTERWARD

    rm /etc/udev/rules.d/70-persistent-net.rules
    

13. shutdown -h now

14. Remove the VM but KEEP THE FILES AROUND.

15. Go to File -> Virtual Media Manager, and remove the disk you created with the VM, but KEEP THE FILE when it asks.

16. Now copy the .vdi file in your VirtualBox path on your hard drive. Alongside it, create a .meta file with a similar filename but different extension. Put something like this in it, adapting it to your newly created image.

     {:os-type-id "RedHat_64",
      :sudo-password "vmfest",
      :no-sudo false,
      :username "vmfest",
      :os-family :centos,
      :os-version "6.4",
      :os-64-bit true,
      :password "vmfest",
      :description "CentOS 6.4 (64bit)"
      :packager :yum}
    

17. Back in vmfest, you can now supply the full path of the .vdi to vmfest.manager/setup-model.
