Nova cores, I would like to request a SFE for the below fix: https://review.openstack.org/#/c/170190/ https://bugs.launchpad.net/nova/+bug/1438226 This change adds a useful error message to help users debug incompatibilities with some versions of a dependency (libvirt). Without this error message the change is of little use. Regards, Stephen Finucane PS: I can redirect this to the i18n mailing list if necessary.
