Thank you for the report, it seems, the issue has been fixed by something else.
** Changed in: horizon Status: In Progress => Invalid -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Dashboard (Horizon). https://bugs.launchpad.net/bugs/1047568 Title: Essex version of Horizon sends null volume size value on boot from volume Status in OpenStack Dashboard (Horizon): Invalid Bug description: When I try to boot from volume using Horizon, the instance fails because Horizon sends a null value for volume size for block_device_mapping. Instead of it booting the volume like this with an integer in the size field: nova boot --image <some-image-uuid> --flavor m1.small --security_group=default --block_device_mapping vda=14::0:0 bov-test It sends it like this, which fails: nova boot --image <some-image-uuid> --flavor m1.small --security_group=default --block_device_mapping vda=14:::0 bov-test The issue seems to be with the create method in horizon-2012.1/horizon/dashboards/nova/images_and_snapshots/images/forms.py at line 168 where it does the dev_mapping: def handle(self, request, data): try: if(len(data['volume']) > 0): if(data['delete_on_terminate']): delete_on_terminate = 1 else: delete_on_terminate = 0 dev_mapping = {data['device_name']: ("%s::%s" % (data['volume'], delete_on_terminate))} else: dev_mapping = None api.server_create(request, data['name'], data['image_id'], data['flavor'], data.get('keypair'), normalize_newlines(data.get('user_data')), data.get('security_groups'), dev_mapping, instance_count=data.get('count')) messages.success(request, _('Instance "%s" launched.') % data["name"]) except: redirect = reverse("horizon:nova:images_and_snapshots:index") exceptions.handle(request, _('Unable to launch instance: %(exc)s'), redirect=redirect) return shortcuts.redirect('horizon:nova:instances_and_volumes:index') This is the stacktrace from nova-api.log:
