The nova.cells.filters.image_properties Module

Image properties filter.

Image metadata named ‘hypervisor_version_requires’ with a version specification may be specified to ensure the build goes to a cell which has hypervisors of the required version.

If either the version requirement on the image or the hypervisor capability of the cell is not present, this filter returns without filtering out the cells.
