Hi,
IaaS is all about elastic computing. I can stretch resources as per my need
- increasing/decreasing the number of cores, RAM allocated etc..
My question is - how does openStack achieve this elasticity for both
computation and RAM.
If I create an image with 2 cores and 4 GB RAM (and one day I
Yes, the instance when running can only use the available resources
from the compute host.

Hi,

rebuilding the instance: openstack will create a snapshot of the

Which driver are you using? For the Vmware driver we found an edge case

Got the solution!
To all who are not able to ping their VM instance, you need to run following on
compute node:

Hi Cedric,

I'm not gonna to tell you which is the best choice for you. It depends on

Okay! But, I don't know how to reproduce this. Mostly because this
situation appeared "out of nothing" and I have no knowledge to go deep
inside OpenStack to see the problem in details.
Nevertheless, I can open my system for debug.
Also, I'll try to get more details about what's going on here...
Okay, I got it...
"Tenant B / Project B", have only 1 member, and it is NOT the user from
"Tenant A".
But, as I said, the user from "Tenant A", is seeing the VNC consoles of
Tenant B VMs anyway, I'm sure this is a security breach.

There is no point in using 8 virtual cores in compute node with 2

Of course, if you don't plan on using that machine for any real work,
you can do it.

It depends on the use-case, there is a point when most of the time the VMs

A use-case yahoo! is doing is letting developers have many VMs, in this

There are much bigger differences for why u should not over-provision

Okay guys, no problem, I can fill a BUG as I did lots of times before using
Launchpad but, I am unable to reproduce this problem in a fresh

I can give full access to my cloud for the experts but, I don't know if

Hi all,
I’m currently going through the havana install guide for a yum-based distro and
planning my required hardware. I was hoping to only use two hosts and needed
some clarification around neutron:
Do i need a dedicated network node (exclusive of controller and compute) if i
want to use neut
You don't need a three-node architecture (controller, network, and compute)
to deploy the Networking/Neutron service, but it seems to work best with
the installation guide and also simplifies debugging.

I think you're referring to this one:

I have done in two modes controller and compute and works fine with no problems
I have not chk the link yet bit you should have no problem with this mode.

Thanks everyone for your valuable point.
Kindly allow me to put my Question in different way.
Shall any VM use distributed(for eg. RAM from the different host) resources
at the same time?
or
Shall any VM use two cores(that lies on different hosts) at the same time?,
in the distributed fashion.
DB locked stack trace is a known issue.
How fast did you push 100 objects and what's your HW spec there ?
You can check for the existence of 404 container by swift-get-node.
