Thanks for response Zaneb !

Is it somthing like this ? openstack overcloud deploy --templates -e /home/stack/templates/node-info.yaml -e /my/yaml --timeout 90

2018-05-31 05:55:49 -0500 asked a question overcloud composite with dpdk and sriov stack fails

Hi All,

I have deployed RHOSP12 undercloud(director VM) and now I'm deploying RHOSP12 overcloud with 9 nodes: 3 Controller, 2 Computes with OVS-Dpdk, 2 Computes with SRIOV, 2 Ceph Storage nodes.

I'm facing issue during overcloud heat stack deployment with the error below: image description

I analysed the heat stacks/resources and found reason for which as deployment cancelled: image description

Also i have attached the output from the command openstack stack failures list overcloud --long here.

Yet all my overcloud nodes(3 controllers, 4 computes, 2 ceph) are active and running. Logged into the overcloud controller and observed the /var/log/messages contents as below:

image description

I increased the timeout and tried but still failed with same issue!. I'm ok to share any results/logs if needed. Appreciate any kind of help/inputs to debug further and resolve issue to make my overcloud up.

--Thanks Praveen N

hi, plz share your /etc/cinder/cinder.conf file contents

2018-04-30 05:01:07 -0500 commented answer packstack --allinone

packstack does not work properly if NetworkManager service is active. You need to disable NetworkManager service and preferable do "setenforce 0 " before invoking packstack installation.

hi check the cinder volumes and delete if any unused cinder volumes are existing. Later give a try.

2018-03-11 13:49:34 -0500 answered a question cannot connect to instance console

Hi Navya,

Your question doesn't mention about the mode of OpenStack deployment or number of nodes. General check i am suggesting below: Please check for vncserver_proxyclient_address in nova.conf file and ensure the hostname is proper . Else replace it with correct IP. Then restart nova-compute service. Hope this helps.

--Regards

2018-03-11 13:35:00 -0500 answered a question VMware integrated OpenStack VMs not getting IP

Hello,

One Possible WorkAround/ Solution is given below: With VIO, i think the glance image format supported are vmdk and maybe iso, qcow2 may not work. For testing, convert qcow2 image to vmdk and upload it to glance later edit metadata for this vmdk image as below:

edit metadata of image

After updating the metadata try spinning up of instances and ping test.

2017-11-02 08:45:33 -0500 marked best answer Connection to libvirt failed

Am installing Openstack mitaka (single Ubuntu 14 vm - all in one controller with neutron linuxbridge) deploying through the ansible playbooks. Once the deployment is completed am able to see the services (nova, neutron etc )are active. But when i try to launch an instance, vm is getting to ERROR state.

Hi have you tested launching instances using cirros ? Are using Neutron with Linuxbridge or OpenVSwitch. How you have installed openstack it is manual installation of services or testing with Packstack?
