A couple of years ago there was work done with an alternate scheduler
called Haizea in the OpenNebula 1.x series. Has that been kept
up to date and would it still work with OpenNebula 3.x?
That scheduler was supposed to address fair-share issues like that.

Hi,
That's currently not possible. The scheduler can prioritize the hosts where
each VM will be deployed, but not which VMs to deploy first.

is it possible to give priority to particular VM with rank
policy...
because in the link
http://opennebula.org/documentation:rel3.2:schg, there is one
option for custom rank....
so please guide me about this.
is it possible to made custom rank? if yes than please guide
about this....
Thanks.....
Hi juan Luis...
as per the my knowledge, i think load aware policy might be
helpful for you...
Rank = "-FREECPU"

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

Hi Jaime
Thanks for the hint, this is what I was thinking and
what I need to put in place. However a second
question comes into my mind, is it possible to set
up the scheduler policies programatically? Meaning
that I'd like to generate an energy aware policy
with wich I'd like to set up the scheudler with a
Packing policy in X nodes.
Cheers

Hi Juan Luis,
I forgot to clarify that in our scheduler the user
can specify what deployment policy to use, which I
believe is what you're looking for.

ies
The difference with the other ecosystem projects is
that the projects I mentioned before perform
migrations after deployment to optimize the use of
resources.

Jaime

Hi
I'd like to know whether if it is
possible to tel opennebula to deploy the
VMs on specific hosts in order to save
energy in the data center. I know that
the scheduler does something similar to
that by checking from time to time where
the VMs are running and moving
consolidating them in the less hosts as
possible, but I'd like to know if by
some short of energy efficiency policy
this can be controled by the user.
Thank you
Cheers
JuanLu
