Hi all:
There exist nova options ('reserved_host_disk_mb' and
'reserved_host_memory_mb') which allow reserving disk and ram in
hypervisors (vCPU seems not be reservable). [1]
On the other hand, during compute scheduling process [2], weigthing
step sorts hypervisors according metrics configurable by operators.

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,
You will need to create a custom nova scheduler filter to achieve
this.

see the " Customizing the OpenStack Compute (nova) Scheduler"
section.
