Hi, Using the sched.conf file, you can only define global policies for all VMs and Hosts. If you need to use different policies for a group of Hosts, I would add a new attribute to the Hosts you want to apply the policy, let's say POLICY=PACKING. Then add to all the VMs you want to deploy in this group/policy the following [1]:
REQUIREMENTS="POLICY=PACKING" RANK = RUNNING_VMS Regards [1] http://opennebula.org/documentation:documentation:template#placement_section -- Carlos Martín, MSc Project Engineer OpenNebula - The Open-source Solution for Data Center Virtualization www.OpenNebula.org | [email protected] | @OpenNebula<http://twitter.com/opennebula><[email protected]> 2012/3/15 Juan Luis Prieto Martínez <[email protected]> > Hi Jaime > > Thanks for the hint, this is what I was thinking and what I need to put in > place.
