Hi,

for implement High Availability in OpenStack installation there are a lots of consideration that you have to do before deploy it.

What I can suggest to you is to approciate to Mirantis Fuel deploy model (http://www.mirantis.com) that enable you to deploy a super HA and extensible installation of OpenStack.

Hi,

I have configured horizon dashboard with SSL enabled. Horizon works perfectly, but in "Console" tab there is no content visible. With chrome devel console i see that content is blocked because vnc prefix url in iframe tag is HTTP and not HTTPS.

How can I configure to make it visible without click "Click here to show only console" ?

Thanks.

Salvo.

sorry for this

hi,

if you have two or more compute nodes you have to configure SSH key to permit the resize or block migration of a VM to a different compute node.

You can follow this guide that for me is very helpful

Hi,

I set up a Devstack environment in Cent OS 7 from GIT git clone https://github.com/openstack-dev/devs... -b stable/juno

Done successfully and I'm able to login to horizon and launch instances using horizon.

I'm trying to extend the dashboard and add a new one through the following link

http://docs.openstack.org/developer/h...

When I run the command

./run_tests.sh -m startdash mydashboard --target openstack_dashboard/dashboards/mydashboard

I'm getting this error

The exact command where it fails in run_tests.sh is with this

/opt/stack/horizon/tools/with_venv.sh python /opt/stack/horizon/manage.py -f startdash mydashboard --target openstack_dashboard/dashboards/mydashboard

Tried fiddling with ALLOWEDHOSTS entry and PYTHONPATH etc but nothing works. Stuck on it for 2 days, any help would be very helpful.

You can found the link on bottom of this page.

I resolved using "nova image-meta" command.

   usage: nova image-meta <image> <action> <key=value> [<key=value> ...]

   Set or Delete metadata on an image.

   Positional arguments:
     <image>      Name or ID of image
     <action>     Actions: 'set' or 'delete'
     <key=value>  Metadata to add/update or delete (only key is necessary on
                  delete)

I know, but I don't like the phrase "delete all image properties not explicitly set in the update request". :)

Hi,

with the command

glance image-update --property my_prop=1 <image_id>

I can store the value of my custom property to my image. But, how can I unset/remove definitively this property ? I try with:

glance image-update --property my_prop= <image_id>

but set the value of property to None.

Thanks,

It is similar to the question asked here but i am looking if there is any way to get the version information using the REST end points?

Hi,

a possible solution is to modify the code of VNC Console (that is available on https://github.com/kanaka/noVNC) and disable/remove the button with id="sendCtrlAltDelButton" on vnc_auto.html file.

In your openstack installation you can found vnc_auto.html under /usr/share/novnc/vnc_auto.html

After I launched a instance with network A, I want to add an IP of another network B to this instance. I have tried using these two commands to do above operation:

neutron port-create ------ to create a new port
nova interface-attach ------- to attach the new port to my instance

But after executing the two commands,I can not ping the new IP from other instances in network B. So,how can I do? And it must be completed online without stopping the instance.

I think this is not a real question. Can you adjust your question, please ?

I've installed the ceilometer in fedora 20. As per the the document mentioned in the openstack site. But while running the following command, am getting connection refused.

[root@controller ~]# ceilometer meter-list
Error communicating with http://controller:8777 [Errno 111] Connection refused

Trobleshooting:

1. Disabled selinux and iptables..
2. uncommented the port 8777 in the celometer.conf file..
3. verified with netstat command the 8777 port was not listening.

Please advise.

Thanks, -Syed.

The "Vcpu" meter in the ceilometer meter-list tells you about the number of Vcpu's assigned to that instance. How can we find the number of Vcpu's the instance is using at the moment.

For example: If I create an instance and assign it 5 Vcpu's how can I check the number of Vcpus the instance is using at the moment.

Kindly provide some information on this.

Ok. What about your neutron-lbaas.conf and neutron.conf ? Can you post your config ?

What kind of configuration do you use ? Can you post your configuration ?

Have you enable libvirtd_opts="-d -l" in /etc/default/libvirt-bin ?

Which one is the correct answer for you? :)

Thanks for your time and attention.

Or you can view volumes of single tenant with:

# cinder --os-tenant-name <tenant_name> list

Yes. You can assign a IP via horizon when you add an network as a router interface or via command line creating first a port with a your IP and next adding to the router interface :

# neutron port-create --fixed-ip subnet_id=<your_subnet_id>,ip_address=192.168.1.20 <your_network_id>

the previous command return the ID of reserved port and next you can add port to router:

# neutron router-interface-add <your_router_id> port=<your_port_id>

Hi,

the error message is clear "Live migration of instances with config drives is not supported in libvirt unless libvirt instance path and drive data is shared across compute nodes."

What kind of shared storage do you use ? NFS or Ceph ? If you don't use a shared storage you cannot use live migration.

Otherwise, if you have a shared storage you can check if you have setting force_config_drive different from None in nova.conf.

What version of openstack do you use ?

Hi,

I need some help about VM live migration (block migration). I am running 1 controller and 2 compute nodes in a devstack environment with stable/kilo branch.

Hi there,

I've successfully installed openstack with rbd volumes backend but experiencing issues with live migration. I'm getting "Failed to compute_task_migrate_server: node01is not on shared storage: Live migration can not be used without shared storageFailed to compute_task_migrate_server: node01is not on shared storage: Live migration can not be used without shared storage" error. I guess it should be addressed soon by https://review.openstack.org/#/c/91722/.

But even though I've failed with block migration. Getting "NoBlockMigrationForConfigDriveInLibVirt: Block migration of instances with config drives is not supported in libvirt." I'm trying to migrate default m1.tiny flavor instance

$ nova flavor-list 

+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| ID | Name      | Memory_MB | Disk | Ephemeral | Swap | VCPUs | RXTX_Factor | Is_Public |
+----+-----------+-----------+------+-----------+------+-------+-------------+-----------+
| 1  | m1.tiny   | 512       | 1    | 0         |      | 1     | 1.0         | True      |

if makes sense.

Any thoughts of how to set up live migration with rbd storage backend properly would be appreciated.

Thank you,

Pavel

Hi,

I installed Kilo release on three node x86 based cluster. I'm not able to launch an instance and while debugging it I see the following error in /var/log/libvirt/libvirtd.log on the compute node.

 27184: error : netcfStateCleanup:111 : internal error: Attempt to close netcf state driver with open connections
 27396: info : libvirt version: 1.2.8, package: 1.2.8-0ubuntu11.8
 27396: error : virSecurityDriverLookup:80 : unsupported configuration: Security driver apparmor not enabled

I googled for above errors, but didn't find any concrete answer. Does anyone know the cause of above error message ?

Thank you.

What version of OpenStack do you have ?

Openstack Kilo release Ceph storage backend

I have run into an issue lately where I create a snapshot of a running instance, while the snapshot state is "image pending upload" And "Queued" state in the image service, I cant access my Instance

I cant access it via the console, ssh and I ran a continuous ping to the floating IP and it times out, but the instance still shows running on the dashboard

As soon as the instance state is "Image uploading" and in the image service "saving" The instance becomes available again,

Is this a know issue ? All of this is done via Horizon dashboard

I can see the following in the logs on the compute:

Hi,
