1. System requirements
OVX is a fairly heavy piece of software in its current implementation and these system requirements should not be taken too lightly – the number of slices, size of the flowspace, and number of datapaths present in your network all contribute to the scaling factors. Only the most trivial of environments can tolerate the minimum system requirements.

2. Binary installation
Under construction. Deb and rpm packages will be distributed soon.
3. Installation from source
You will need to install the following packages:
* Git,
* Oracle Java, version 7 (version 8 is unsupported for now),
* Apache Maven,
* Python, version 2.7 or higher, and
* MongoDB is optional, install if you want to use the OVX persistence features.
Then you can clone the OVX source
git clone https://github.com/OPENNETWORKINGLAB/OpenVirteX.git -b 0.0-MAINT
Normally you want to run the current stable branch 0.0-MAINT. If you are feeling adventurous or need some recently added features, replace 0.0-MAINT by 0.1-DEV in the previous command.
If you want to use OpenVirteX that supports OpenFlow 1.3, replace 0.0-MAINT into OpenFlow1.3 from the above command.
