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')
