stoney cloud: Demo-System Installation

Overview

The stoney cloud builds upon various standard open source components and can be run on commodity hardware. The Demo-Node installation consists of one node with the following software-stack installed:

• The Linux kernel based virtualization technology.
• An OpenLDAP Directory Server for the storage of the stoney cloud user and service related data with the web based management VM-Manager interface and the Linux kernel based virtualization technology.

Prerequisites

The following items and conditions are required to be able to install and configure a stoney cloud environment:

• A dedicated server which fulfils the following requirements:
  • 64-Bit Intel with VT-Technologie (AMD is not tested at the moment, but it should work).
  • 8 Gigabyte Memory (more is better).
  • 130 Gigabyte up to 2 Terabyte disks (for the first RAID-Set, the 2 Terabyte restriction applies).
    • For the mass storage (where the virtual machines are stored) we recommend a second RAID-Set configured as RAID6-Set with battery backup.
  • One physical Ethernet Interfaces.

Limitations

During the installation of the Gentoo Linux operating system, the first physical Ethernet Interface ist automatically configured with DHCP. This means, you need a working DHCP Server. The virtual machines running on the stoney cloud Demo-System are NATed. This means, you can not access the virtual machines from externally.

Installation

Booting

Choose 1) FOSS-Cloud Installer: default boot options

Keymap Selection

Set the desired keymap. The following example works for the German speaking part of Switzerland: 46 (de_CH)

Start the Installation

Start the actual installation by typing: yes

Choose the Single-Node Installation

Choose the Single-Node Installation by typing: 2

Device Selection

You'll need to select a SCIS, SATA, PATA or virtual disk. The following installation in done in a virtualized environment, therefore we choose the virtual disk: vda

If you type yes, you'll be deleting all the existing data on the chosen disk: yes

Proceeding ...

The installation proceeds with the partitioning of the disk and the installation of the operating system:

You can ignore the message "Error: /dev/vda: unrecognised disk label" as this is normal for a first installation in a virtual disk.

Network

Now we configure the network. In this example, we only have one network interface: eth0

We choose the automatic DCHP configuration: yes

Reboot

Now we can reboot the system:

Skipping Checks

To skip checks, type no when asked:

 Do you want to start the installation?
yes or no?: no

Then manually restart the stoney cloud installer with the desired options. For example

/mnt/cdrom/foss-cloud-installer -c

Options:

-c: Skip CPU requirement checks
-m: Skip memory requirement checks
-s: Skip CPU and memory requirement checks
