[one-users] Networking in Open Nebula

[Tino Vazquez]

Hi Shweta,

You need to include a script within the VM so it set the correct
network attributes at boot time. Take a look at the last section of
[1].

Another detail to take into account is that the vmcontext.sh script
derives the IP address from the MAc address, so the following lease
won't make the VM to have the rigth IP address:

LEASES= [IP="172.16.2.205",MAC="50:20:20:20:20:20"]

If you specify just the IP address, OpenNebula will compute the right MAC.

Regards,

-Tino
