Hi,
Does anyone use Zookeeper[1], Memcache[2] Nova ServiceGroup Driver ?
If yes how has been your experience with it. It was noticed that most of
the deployment try to use the default Database driver[3]. Any experiences
with Zookeeper, Memcache driver will be helpful.

Hi All,
I am working on the Nested Quota Driver for Cinder [1] and with that effort
trying to clean up some of the existing quota related issues we have with
Cinder. Few of the obvious ones which we saw recently is [2] where usage
and reservation quota was being deleted on quota deletion.

Hi,
While developing Nested Quota Driver for Cinder, when performing
show/update/delete following restrictions apply :-
1. show : Only user who is admin or admin in parent or admin in root
project should be able to perform show/view the quota of the leaf projects.
2. update : Only user admin in
Hi All,
As discussed in today's Magnum weekly meeting I had shown interest to work
on [1].
Problem :-
Currently objects (pod/rc/service) are read from the database. In order for
native clients to work, they must be read from the ReST bay endpoint. To
execute native clients, we must have one trut
Hi All,
As part of Liberty spec [1] was approved with the conclusion that
nova.services data be stored and managed by respective driver backend that
is selected by the CONF.servicegroup_driver (which can be
DB/Zookeeper/Memcache).
When this spec was proposed again for Mitaka[3], the idea that has

Hi All,
I see negative values being returned by resource tracker, which is
surprising, since enough capacity is available on Hypervisor (as seen
through df -ha output [0]). In my setup I have configured nova.conf to
created instance snapshot locally and I *don't have* disk-filter enabled.
Local i
I am highly supportive for the idea of Nova Quota sub-team, for something
as complex as Quota, as it helps to move quickly on reviews and changes.
Agree with John, a test framework to test quotas will be helpful and can be
one of the first task the Nova Quota sub team can focus on as that will lay
Hi All,
Currently, it is possible to create unlimited number of resource like
bay/pod/service/. In Magnum, there should be a limitation for user or
project to create Magnum resource,
and the limitation should be configurable[1].
I proposed following design :-

Hi All,
As part of the cross project Quota library effort [1] there has been a
discussion around the need for reservations or getting rid of reservations
altogether.
It is believed that reservation help to to reserve a set of resources
beforehand and hence eventually preventing any other upcoming
Hi All,
For people who missed the design summit session on Delimiter - Cross
project Quota enforcement library here is a gist of what we discussed.
Etherpad [1] captures the details.
1. Delimiter will not be responsible for rate-limiting.
2. Delimiter will not maintain data for the projects.
