Meteohub can be used as virtual machine with VMware Server 2.0 (or never), VMware Player 2.5 (or never) and VMware Workstation 6.5.1 (or never). This allows to try Meteohub without buying hardware. In case of an already 24/7 running server one or more Meteohub instances can be hosted with very limited additional resources.
Download section has a compacted image of a VMware guest instance, that can be used inside a running VMware environment.
Installation on VMware Player 2.5 and VMware Workstation 6.5.1 VMware Player can be downloaded and used for free from "www.vmware.com". After having installed this, the following steps have to be done:
Meteohub has been tested and ported on "official" platforms NSLU2, ebox 2300/3300/4300, fit-PC Slim, ALIX.1D/3D2 and SheevaPlug. On these platforms Meteohub can be easily installed by a predefined disk images. You will not need any Linux knowledge to do this. Taking a generic x86 version of Meteohub an advanced Linux user might have the option to install Meteohub on other x86 platforms as well. If you have an unused, low-power, old PC somewhere around, this might be converted into a Meteohub system without too much of an effort, as far as you are quite familiar with Linux and the processor is at least a 486 type.
You will find a documentation how to do this here: OS_Obligations#Meteohub_on_x86_Platforms.
Please understand that "meteohub.de" cannot support you when trying an installation on unknown hardware. You will need some in-depth Linux knowledge to get it working. As Linux itself and meteohub installation scripts are completely open, this can be done when you have sufficient Linux skills.
