[one-users] VM Placement

[Carlos Martín Sánchez]

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
