Hi Don!
Yes, maybe quota is not the right word.
What I want is somehow to adjust the total number of vCPUs and the
total number of RAM that can be assigned to all VMs for a specific
hypervisor. Then Openstack based on these settings will accept or deny
the creation of a new VM at that hypervisor and will continue at the
next hypervisor.
Besides that is there a way to define hypervisor priority?? For
instance if I want to start putting VMs on one hypervisor rather than on
another but don't want to do it manually using the zone setting. Can I
configure it?
Thanks a lot for your answers!
All the best,
George

I have a multi-node installation where each node has different
physical specification from the others.
How can I limit each one to be able to start a specific number of
VMs based on the available flavors and the available specs?
Best regards,
You probably dont mean quota, which applies to a tenant.
cpu_allocation_ratio=16
ram_allocation_ratio=3
reserved_host_memory_mb=4096
are 3 things that can be set in nova.conf, but i dont think these
will
achieve your goal of making nova scheduler make different decisions.
Generally,
http://docs.openstack.org/juno/config-reference/content/section_compute-scheduler.html
[2]
shows the options the scheduler will look at.
http://docs.openstack.org/developer/nova/devref/filter_scheduler.html
[3] has some description, you can see the JsonFilter is probably
what you want.
