I find the roles ( admin, KeystoneAdmin, KeystoneServiceAdmin) are created
in devstack. I think each role has it rights to use functions or services.
Now I want to know how many roles in keystone can be created and what are
use of them .
For example, I only want a role only can create/delete
Looks like you don't have xenapi installed, somehow.
This should do the trick:
pip install xenapi
It would be interesting to know how you got to that error? Are you using
DevStack?
Thanks,

Hi all,
on the very useful www.referencearchitecture.org website, and in every
piece of documentation on Swift, I never found anything like a NAS
attached to a storage node. It was all about DAS solution.
Is there a specific reason why a NAS wouldn't be a good choice to build
a swift
Keystone does not have the concept of least privilege for such operations.
The notion of roles with capabilities in Keystone is something that maybe
can be addressed in Folsom

Generally, you would introduce latency in the storage system by using a NAS
attached to a storage drive. Also, at scale, your costs will be dominated by
drive, so you will want to optimize the storage nodes for dense, cheap storage.

Hi,
I have made some tests with openstack api v1.1. Now I try to send some
information to the virtual server by using metadata and personality
files, but I am not able to find this information from my virtual
server.
I am able to create the virtual server successfully with curl:

Hello,
I was actually going to start working on that today as we have review 4893
merged as of last night, basically when you connect with glance to swift :
https://github.com/openstack/glance/blob/master/glance/store/swift.py#L306
You need to have an option in glance to connect to a auth 2.0
Hey Michael,
*Is there a specific reason why a NAS wouldn't be a good choice to build a
swift infrastructure?*
Why would that make sense to you?
The idea of Swift is to distribute the files over a large amount of
inexpensive servers and prevent data loss by keeping multiple copies.
Whereas in

will do just as well ?

*I don't think anything prevents integrating Swift storage nodes with a
NAS. Latency could be increased but depending on load, network capacity
(shared vs dedicated), and use of caching, it is possible to achieve a good
performance.*
Yes, but why would you do so..

Hi Stackers,
So, in diagnosing a few things on TryStack yesterday, I ran into an
interesting problem with snapshotting that I'm hoping to get some advice on.

The TryStack codebase is Diablo, however the code involved in this
particular problem I believe is the same in

storage solution) with Openstack Nova:

That's Nova, not Swift..
In case of Nova, a NAS or SAN approach makes very much sense.

There are numerous reasons why you would want your Swift Object Server to also
host a NAS server.
But whether you are talking Nova volumes or Swift Objects, you would generally
want the Volume Server
or Object Server to access those directly rather than via NAS over a general
network
Brebner, Gavin asked:

Because you are interested in the total cost.
Using excessive network replication rather than local replication makes for a
more expensive

Howdy, folks. I've been working on a replacement for nova's
rate-limiting middleware that will handle the multiple-node case, and
I've developed a fairly generic rate-limiting package, along with a
second package that adapts it to nova. (This means you could also use

Is there anyway we can make sure that blueprints have a lot more in them.
That's great for a introduction but I'd really like to see design plans, how it
