Hi Michal, many thanks for the prompt answer. That explains our sightings were we were not able to deploy an instance with more vRAM than we had physically left. Cheers, Oliver Am 12.12.2024 um 10:47 schrieb Michał Nasiadka:
Hi Oliver,
Here’s a link to the template we’re using - https://opendev.org/openstack/kolla-ansible/src/commit/e628cbddb19fa26de7a5f...
As you can see we’re setting ram_allocation_ratio to 1.0 by default, but we do not set cpu or disk allocation ratios - so the defaults there come from Nova itself. Check (and change 2024.2 to your OpenStack release): - https://docs.openstack.org/nova/2024.2/configuration/config.html#DEFAULT.ini... - https://docs.openstack.org/nova/2024.2/configuration/config.html#DEFAULT.cpu... - https://docs.openstack.org/nova/2024.2/configuration/config.html#DEFAULT.ini... - https://docs.openstack.org/nova/2024.2/configuration/config.html#DEFAULT.dis...
Hope that helps,
Michal

Hi all,
what are the default values for:
cpu_allocation_ratio
ram_allocation_ratio
disk_allocation_ratio
when using kolla-ansible?
I can't seem to find any clear statement about it.
Currently I assume they are 1.0 for each.
Cheers,
Oliver
