Hi, There are two contextualization mechanisms available in OpenNebula: the automatic IP assignment, and a more generic way to give any file and configuration parameters.
To make the network work, you can forget about the CONTEXT section, the context cdrom and the init.sh script; just focus on the vmcontext script configuration [1] Regards [1] http://opennebula.org/documentation:rel3.4:cong#using_virtual_network_leases_within_a_virtual_machine -- Carlos Martín, MSc Project Engineer OpenNebula - The Open-source Solution for Data Center Virtualization www.OpenNebula.org | cmar...@opennebula.org | @OpenNebula<http://twitter.com/opennebula><cmar...@opennebula.org> On Wed, Jun 13, 2012 at 6:47 AM, ankit anand <ankit.s.an...@gmail.com>wrote: > Also, I am not able to statically assign vm the IP, i want to give .
