So you’ve created your all new VM guest, uploaded it’s image, attached it to a template and started your VM. OpenNebula tells you that the VM has an IP address from your virtual network, but sadly you neither can access the VM via this address, nor is the interface in your linux host configured with the settings from your virtual network.

The solution for this problem is quite easy, install the package one-context:

  1. Download the correct version matching your Linux guest OS’s package manager and your OpenNebula version from here:
  2. Install the package in your guest VM
  3. Reboot your guest VM and voila your network is configured

Pro-Tip: Do this before you upload your VM image to OpenNebula
