Can someone help me how to set up the open nebula into oracle VM virtual box Machine, please!
Hi @thorfinn 
Welcome to the OpenNebula Forum! 
Could you give me more details about this problem? Are you experiencing any problems installing OpenNebula packages or having trouble configuring any specific OpenNabula components? What distribution are you using for this installation?
I recommend you to follow the steps described in the installation guide of the docuemtnation.
Best,
Victor.
