Re: [nova] Strict isolation of group of hosts for image

Hi Vrushali-

'CUSTOM_RESOURCE_CLASS',  it's getting removed when the compute service periodic task updates the inventory.

Yup. The virt driver is the source of truth for the compute node's inventory. You can't (yet [1]) add or change inventories except by modifying the actual code (the compute driver's update_provider_tree method ([2] for libvirt)).

Here we are trying to Test granular resource request.

I'm curious why you care about this aspect. Perhaps there's a way to do this "natively" with VGPU or bandwidth... efried [1] https://review.opendev.org/612497 [2] https://opendev.org/openstack/nova/src/commit/707deb158996d540111c23afd8c916...
