Hello,

Well, first of all, quotas refer to the amount of resources a tenant / user is allowed to use, and they are set by admins, or users with admin roles in OpenStack. What you are refering to, is the amount of available resources.

And yes, this is a well known fact that nova-compute does not take into account the actual used resources when reporting the available resources to the nova-scheduler / placement API (it's not related to Hyper-V - nova only cares about what it's deployed through it).

Even so, there is a way to solve your resource allocation / scheduling issues.

You can set these config options in your compute nodes' nova.conf files:

[DEFAULT]
reserved_host_disk_mb = ...
reserved_host_memory_mb = ...

For more details, see https://docs.openstack.org/ocata/config-reference/compute/config-options.html

Hope this helps!

Best regards,

Claudiu Belu
