[Openstack] Hiding a Panel in Dashboard
Hi folks, I have a doubt. Generally, if we create a panel, we need to create a new directory under '.../horizon/dashboard/nova/' and add that in '.../horizon/dashboards/nova/dashboard.py'. Let us suppose panel directory name is 'sample_panel'. I created a directory namely 'sample_panel' under the directory '.../horizon/dashboard/nova/'. I didn't add that panel in dashboard.py. When I tried to access that module with the URL: http://localhost/horizon/nova/sample_panel/, I got the following error: 'The page you were looking for doesn't exist' If I add that panel name in 'dashboard.py', I am able to access the URL with out any errors. Can we hide a panel in dashboard from displaying and use that module at the same time? Thanks in advance. -- Srikanth. ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

[Openstack] [Horizon] tables.DeleteAction not working
Hi, I created a custom table in Quantum DB, and getting rows from that, and show as Table in Horizon. For each row, I put only action 'Delete', and called subsequent class for eg. 'DeleteRow(tables.DeleteAction)'. In this, I wrote 'delete' function, in which I am calling quantum API to delete the row from DB. But, however, If I click DeleteRow button in horizon, 'delete()' function in the class is not triggering. And, as a result, row is not deleting from DB.

From these debug logs, quantum-server ovs-agent plug-in able to get the data from DB and sending. But, at quantumclient, I am not able get that data.

[Openstack] File Injection through Horizon
Hi,
I am trying to implement File Injection through Openstack Dashboard. That
means, while creating instance from 'Launch Instance', I will give file
path of a file, which I need to inject.
For that, I modified the following file:
*/usr/lib/python2.7/dist-packages/novaclient/v1_1/servers.py*
*
*
In the above file, in the function '*create*', I observed an argument '*
files*' wihch is taking 'None' by default. So, to test the primary
functionality, I gave the '*files*' argument statically in the function.
For that, the first line of that function (Line no. 472) implementation, I
defined '*files' *as below:
*fp = file('/root/inject.txt', 'r')*
*files = {'/root/inject.txt':fp}*
*
*
I followed two methods to create instance:
1. Through Openstack Dashboard
2. Through nova boot command from CLI
*Method 1:*
After that, I restarted apache, and tried to create (launch) an instance
from dashboard. It threw the following AJAX error, by clicking the Launch
button:
*Error: *There was an error submitting the form. Please try again.
*Method 2:*
If I did the same from nova boot command, the instance is creating and file
injection is happening. Both methods are using the same above function '*
create*' in '/usr/lib/python2.7/dist-packages/novaclient/v1_1/servers.py'.
I used the following nova boot command:
*# nova boot --flavor=1 --image=4671e99b-1c01-42e8-94d6-2405a59bab57
testserver*
Can you please let me know, what I am doing wrong here? And also, If I want
to implement File Injection through Openstack Dashboard, what I need to
modify?
Thanks in advance.

Atul is describing a different feature that can be used to achieve similar results. The contents of User-Data will be accessible to the instance via http://169.254.169.254/latest/user-data; - Ubuntu ships with a tool called cloud-init that makes use of this data if available. Eg One of the simple use cases for cloud-init is, if the data starts with #!, it will assume it's a shell script and download + execute it. This can, in a roundabout way, be used to achieve similar results to the file injection feature.

[Openstack] Updating Metadata for an instance.
Hi,
I created an instance with the following command:
*# nova boot --meta creator=srikanth --meta desc='This is a Test
Description' --flavor=1 --image=4671e99b-1c01-42e8-94d6-2405a59bab57
testserver*
*
*
I am able to see a file - 'meta.js' in '/' directory of instance file
system, with the given metadata values. And, I can be able to see those
meta values under 'Instance Detail' of that particular instance in Horizon.
Now, I want to modify the metadata, for example here...I want to change the
metadata value for the key 'creator'.
I used the following CURL command to modify the metadata
*# curl -k -D - -H X-Auth-Token: fba5f4286dc245b4b3c4112d770afe29 -X
'POST' -v
http://10.232.0.3:8774/v2/7a6bf89048d04871bb9b46b4f8509198/servers/329ead9d-7cb9-425c-a0c6-a6175a23aa88/metadata-d
'{ metadata : { creator : kumar }}' -H 'Content-type:
application/json'*
*
*
I got HTTP/1.1 200 OK response, with the modified metadata values. I am
able to see the same on Horizon. But, when I reboot the instance, and see
/meta.js, it has the old values. Why it is showing old values? Metadata
really modified? Please let me know.

Srikanth.

Re: [Openstack] ERROR in ‘/var/log/quantum/agent-dhcp.log’ for FOLSOM-3
Hi Dan, Yes, we have mentioned valid rabbit_host, rabbit_userid and rabbit_password fields in quantum.conf. And also, we gave the same fields in ovs_quantum_plugin.ini also. But, we are getting the same errors in agent-dhcp.log Srikanth.

[Openstack] VM Instance NOT able to get IP
Hi, I'm using Folsom Testing Packages on Ubuntu 12.04., Quantum V2 with OVS Plugin Agent running. I created a network with subnet 10.10.0.0/24. I wanted to create an instance with the created network. I am trying to create that instance in the same Controller Node. The following services are up and running. 1.quantum-server 2.quantum-plugin-openvswitch-agent 3.quantum-dhcp-agent 4.nova-api 5.nova-compute 6.nova-cert 7.nova-consoleauth 8.nova-scheduler 9.novnc The thing is, I am able to create an instance and running. I am able to see the IP in the ‘Horizon’ which is getting it from Database. But, I am not able to see that IP, when I VNC to that machine and execute ‘ifconfig’. When I check the processes running, I am not able to see any 'dnsmasq' and ‘dhcpd’ running with the mentioned subnet. Can anyone please guide me?

Re: [Openstack] VM Instance NOT able to get IP
Hi, I am able to fix the issue. The issue is related to quantum-dhcp-agent. In '/etc/init/quantum-dhcp-agent.conf', I replaced the following *exec start-stop-daemon --start --chuid quantum --exec /usr/bin/quantum-dhcp-agent -- --config-file=/etc/quantum/dhcp_agent.ini --log-file=/var/log/quantum/agent-dhcp.log* with the following *exec start-stop-daemon --start --chuid quantum --exec /usr/bin/quantum-dhcp-agent -- --config-file=/etc/quantum/quantum.conf --config-file=/etc/quantum/dhcp_agent.ini --log-file=/var/log/quantum/dhcp-agent.log* * * Then, restarted 'quantum-dhcp-agent'.

Even if this explain why you do not see dhcpd, we still need to investigate why dnsmasq is not running. From your description, it seems that this is the root cause of your issue. If no dnsmasq instance is seen on the node where dhcp-agent is running, and there are subnets defined in quantum, please check the following: - dhcp_enable is set to True for configured subnets - the dhcp agent successfully connects to the quantum server for retrieving state information. If this does not happen, error should appear in the logs.
