[Openstack] Openstack with ESXi - NetworkNotFoundForBridge: Network could not be found for bridge

[Balamurugan V G]

Hi,

I have a two node OpenStack Folsom Setup. One node runs all services with
KVM. The other nodes is a Compute Node for ESXi 5.1. I have set the
availabality_zones for each of this so that I can schedule instances as per
my need. I am able to operate the instances on the KVM just fine. But when
I launch an instance for ESXi, it goes to ERROR state with the error
'NetworkNotFoundForBridge: Network could not be found for bridge'.

After the vanilla Folsom installation, I was getting an AttribueError which
got fixed after applying the patch at
https://bugs.launchpad.net/nova/+bug/1063885

But then after that, I am seeing this error.

[Openstack] Infiniband + OpenStack.

[zebra x0r]

Hi.

I'm considering a reasonably sized OpenStack deployment shortly (several
thousand cores). One of the decisions I need to make centres around the
type of interconnect I will use to connect the compute nodes, Swift object
storage, shared storage, swift proxies et al.

I have been heavily considering FDR infiniband for this task, but, from
what I can see, IB has only recently become something one might consider
stable for use in OpenStack. My peers are suggesting to me that I should
just stick with 10GbE interconnects and be happy.

I'd like to hear the experiences of people who have or are using IB, or who
have experiences with IB deployments.

Thank you.

In the opening paragraphs:

"companies" currently links directly to
http://www.openstack.org/foundation/companies/ , I think
the encyclopedic norm would be for that link to be in a ref on "more than
150 companies".

"portable software" could link to
http://en.wikipedia.org/wiki/Software_portability

"SUSE Linux" should likely just be SUSE and link to
http://en.wikipedia.org/wiki/SUSE


The strength of the article is also very dependent on the quality of
https://en.wikipedia.org/wiki/Cloud_computing and specifically
https://en.wikipedia.org/wiki/IaaS#Infrastructure_as_a_service_.28IaaS.29
which are not particularly strong, and likely contain "original research."
Possibly, we could rally to improve these as well.


Hope that helps,

Re: [Openstack] Structure Hybrid Compute Nodes

[Narayan Desai]

We have the same basic problems. We have 4 different types of systems
integrated into our system. They all have different ratios of cpu to
memory, and we have some specialized hardware on one class of nodes.

We ended up setting up a series of chassis specific instance
definitions. We then use the filter scheduler to only accept hosts
with a particular configuration for the associated instance types.
(for example, our large memory nodes will only run instances with the
mem. prefix, and won't run generic instance types or ones for other
hardware types -- it seemed silly to waste large memory resources on
1GB ram vms)

It is pretty simple to write filter rules for the filter scheduler to
set this up. You just need instance types and a hostname convention
that you can use to matchmake.

While this seems a little hacky, it works well.

Re: [Openstack] OpenStack (Quantum) Multi-node Set-up with VMware Fusion

[Debojyoti Dutta]

Kyle has one (CCed) that he blogged about but with VXLAN instead of GRE
http://www.siliconloons.com/?p=395

I have a similar one for virtualbox but havent checked it recently. For my
setup, I have a regular NIC with DHCP (eth0) and another one thats host
only with a static IP (eth1). My host IP and public interface params point
to eth1 instead of eth0 as in Kyle's setup.

Another setup is at

+1.  We need more reviewers, IMO; there are constantly 2 pages of
pending code reviews, and I've even seen reviews with a +2 get
auto-abandoned after 2 weeks because no one else has reviewed them.

So I don't know where it's picking up /usr/bin/nova-volume.  The stack

BTW, the reason I think that Cinder is working is that I can see it from 
nova and horizon, create volumes, etc.  Is booting off a snapshot an 
infrequently used feature?  My informed question is, is there a bug in 
nova where it's still using nova-volume instead of cinder for this feature?

 Hi,

 I have a Folsom private openstack cloud in which security is not a
 concern. That is I dont really need the security groups and keypairs etc
 offered by openstack. So all my instances are launched as part of the
 default security group. I have even allowed all TCP and UDP ports(1 to
 65535) and ICMP.

 But when I try to SSH to the floating IP assigned to a Ubuntu instance,
 I get connection refused. When I so 'ssh -vvv', I can see that the
 connection is getting establish but is getting terminated. It seems due to
 missing key pair.

 Is there a way to bypass the keypairs.

 Regards,
 Balu

The wrong bin is running. You should be running /usr/bin/cinder-volume if you

It doesn't look like you have configured cinder properly.

[Openstack] Folsom: boot from volume snapshot using nova.conf and not cinder?

[Blair Zajac]

I've set up a new Folsom instance on an Ubuntu 12.10 system.  Trying to 
launch a new instance booting from a volume snapshot, which failed with 
the below stacktrace saying that nova-volumes cannot be found.  This 
suggests to me that nova is using nova-volumes instead of cinder, even 
though I've set up cinder with a LVM volume group named cinder-volumes:


# nova.con
volume_api_class=nova.volume.cinder.API
osapi_volume_listen_port=5900
# MAKE SURE NO ENTRY FOR osapi_volume anywhere in nova.conf!!!
# Leaving out enabled_apis altogether is NOT sufficient, as it defaults
# to include osapi_volume
enabled_apis=ec2,osapi_compute,metadata


# cinder.conf
volume_name_template = volume-%s
volume_group = cinder-volumes



Is this a known issue?  I've since set 'volume_group = cinder-volumes' 
but I'm guessing this shouldn't be necessary?

Re: [Openstack] Structure Hybrid Compute Nodes

[zebra z zebra]

I actually have the same question, but in a different "shape".

Is it possible to "pin" specific workloads to certain nodes that one knows
need to be of a certain type. I.e ­ can one "pin" certain workloads to high
memory instances, GPU instances etc.

Subject:  [Openstack] Structure Hybrid Compute Nodes

Hello everybody,

Do you know of a way to set to work with OpenStack ComputesNodes containing
different hardware?
In my case, I did tests with different hardware, example 1 compute node with
24processors and 128GB memory VS 1 compute node with 8 processorsand 16GB of
memory.In the test I saw heonly makes divisionnumber of instances between
totalcompute nodes, butit does a calculation for use by node.

It is possibleto make it work withsome kind of calculation to not overload a
node?

Sorry my english google translate hahahah

Re: [Openstack] vm can not get ip

[Rain Li]

Hi, Sam,

I also install Openstack on ubuntu 12.10 via
http://devstack.org/guides/single-machine.html, and get this error as well.
Another weird thing is that I can start an instance from horizon, (it shows
the "successful" message), but I can not access (ping/ssh) the instance
from the controller host machine. I already add the corresponding secgroup
rules. With command "route -n", I can see the route entry for 169.254.0.0.
Hope someone can show some clues for this problem.

Rain Li

Yes but I want to skip this feature of keypairs. I want to be able to SSH

[Openstack] Nova compute for ESXi

[Balamurugan V G]

Hi,

 I am trying to add a ESXi compute node to the stack. So I have a Ubuntu VM
inside the ESXi which I plan to use as the compute node for the ESXi. So on
this Ubuntu VM, I need to install nova-compute. Since there are various
flavors of nova-compute, I assume that I should be installing just the
'nova-compute' from the list below:

root@openstack-esxi:~# apt-cache search nova-compute
nova-compute - OpenStack Compute - compute node
nova-compute-kvm - OpenStack Compute - compute node (KVM)
nova-compute-lxc - OpenStack Compute - compute node (LXC)
nova-compute-qemu - OpenStack Compute - compute node (QEmu)
nova-compute-uml - OpenStack Compute - compute node (UserModeLinux)
nova-compute-xcp - OpenStack Compute - compute node (XCP)
nova-compute-xen - OpenStack Compute - compute node (Xen)
nova-xcp-plugins - OpenStack Compute plugin for the Xen Cloud Platform
root@openstack-esxi:~#

Is my assumption right?

Thanks,
Balu

Re: [Openstack] Bypassing the keypair in Folsom

[JuanFra Rodriguez Cardoso]

Hi Balu:

Before launching an instance, you have to create a keypair
(YOUR_DASHBOARD_IP/dashboard/nova/access_and_security/).
Then, next time you launch an instance, you can choose that keypair created
previously.

Regards,
JuanFra.

[Openstack] Is the Quantum a network bottleneck

[Balamurugan V G]

Hi,

In an Openstack deployment using Quantum, the compute nodes access the
public/external network via the network node (as per the diagram
http://docs.openstack.org/trunk/openstack-network/admin/content/connectivity.html
).

So if I have a hundred compute nodes each running hundred instances,
wouldn't the link to the network node choke? Also wouldnt the network
node's resources be a bottleneck?

Balu

[Openstack] Bypassing the keypair in Folsom

[Balamurugan V G]

Hi,

I have a Folsom private openstack cloud in which security is not a concern.
That is I dont really need the security groups and keypairs etc offered by
openstack. So all my instances are launched as part of the default security
group. I have even allowed all TCP and UDP ports(1 to 65535) and ICMP.

But when I try to SSH to the floating IP assigned to a Ubuntu instance, I
get connection refused. When I so 'ssh -vvv', I can see that the connection
is getting establish but is getting terminated. It seems due to missing key
pair.

Is there a way to bypass the keypairs.

You can use some of the other back-end driver tests as a starting point or
reference, and submit a review and go from there.  Also feel free to grab
somebody on IRC in #openstack-cinder and maybe we can help answer more
detailed questions you have there.

Re: [Openstack] Instances and ARP

[Joe Breu]

In the interim you can set vpn_image_id to the UUID of an image that you want 
launched without mac and IP spoofing filters created.  On the compute node the 
instance is launched with the nova-vpn ruleset which allows DHCP traffic.

At current this only works with a single image UUID.

Hi guys,

I've got openstack essex configured with vlanmanager and an external gateway 
and all my networking runs ok generally.

However, I'm trying to setup Linux HA on two instances. They run on separate 
compute nodes and can see each other just fine. hb_takeover and hb_standby 
works perfectly. The problem is that nothing outside of the instance with the 
HA IP address can connect to it.

It seems that something is ignoring the arp is-at from the instance. Doing a 
tcpdump on the compute node's bridged network and the instance's eth0 I can arp 
requests and responses fine for its main IP, but when I try to get to the alias 
address, I see arp requests only on the compute side. On the instance side I 
see it responding, but this doesn't show up on the bridged interface on the 
compute node.

Has anyone seen this before? My google-fu is failing to find anything.

Kind regards

[Openstack] Structure Hybrid Compute Nodes

[Danilo Perogil]

Hello everybody,

Do you know of a way to set to work with OpenStack Computes Nodes containing 
different hardware?
In my case, I did tests with different hardware, example 1 compute node with 24 
processors and 128GB memory VS 1 compute node with 8 processors and 16GB of 
memory. In the test I saw he only makes division number of instances between 
total compute nodes, but it does a calculation for use by node.

It is possible to make it work with some kind of calculation to not overload a 
node?

Sorry my english google translate hahahah

[Openstack] Unify services and hosts API

[Alessio Ababilov]

Hi everyone!

I noticed that API of two nova extensions (namely hosts and services)
is inconsistent with other parts of API.

First of all, you have to make a GET query for host shutdown, startup,
or reboot. It's _very strange_ and it should be regular actions
executed with a POST query.

Second, Nova API usually returns updated entities in response to
update queries. For example, if you update a host aggregate, you will
obtain something like {  "aggregate": { ... } } . Host and services
API omits the wrapping dictionary and returns, for example,  {...}
instead of {"host":{...}} .

I've updated these extensions in https://review.openstack.org/18577 .
The patch has one -2 cause it updates API and one +2 since these
changes are made to extensions, not to main API.

Could you pay attention to it, please?

is it possible to use active directory and mysql database at the same time?
for example, keystone first query the user in AD, if nothing is found, it
then query mysql database.

The motivation is that I want to store service users(glance, nova) in mysql
and use current AD database for employee login.
