Hi all,

I am trying to run OpenStack with OpenDayLight. There are a controller node and a compute node. I have used the instructions and the virtual machine(s) from

I am able to use Dashoard but I get the following errors:

  • In Admin -> System Panel -> Overview

    Error: Unable to retrieve volume limit information.

  • In Admin -> SystemPanel -> System Info

    Error: Unable to get quota info.

  • In Admin -> System Panel -> Volumes

    Error: Unable to retrieve volume list.

    Error: Unable to retrieve volume types

These errors appear also in different places in the Horizon menu.

Have you ever faced them? What could be the causes? How could I do?

I specify that I am new to OpenStack and ODL.

Thank you.


When I try to create a new instance I get:

Error: Unable to retrieve list of volume snapshots.

Error: Unable to retrieve list of volumes.

Error: There was an error submitting the form. Please try again.

Error: Unable to retrieve list of volume snapshots.

Error: Unable to retrieve list of volumes.

Update1:(see also UPDATE2 at the bottom) I suspect the issues that I presented above could be related to the following error(seen in

The mysql root password is 'mysql'. Even-though the virtual machine comes with exactly the same password, I had to reset it using the commands described in due to ERROR 1045 (28000): Access denied for user 'root'@'fedora-odl-1' (using password: YES) that I solved using mysql --user=root --password=mysql mysql [........] contains all the messages that I got during the stack process, including the section above.

In the following I would like to write the configuration of both control(fedora-odl-1) and compute(fedora-odl-2) nodes:

[odl@fedora-odl-1 opendaylight]$ ifconfig eth2
    inet  netmask  broadcast
[odl@fedora-odl-2 devstack]$ ifconfig eth2
    inet  netmask  broadcast

This is the local.conf in the controller node:


# Only uncomment the below two lines if you are running on Fedora
disable_service rabbit
enable_service qpid
#disable_service n-cpu
enable_service n-cond
disable_service n-net
enable_service q-svc
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service quantum
enable_service tempest

Yes, it is probably related to mysql problem (nothing to do with opendaylight) To which ip your hostname is resoved? (e.g. when you ping fedora-odl-1 ?) maybe try to change your /etc/hosts such that your hostname resolves to, fedora-odl-1 ?

initially the hostname was resolved to After swapping the lines in hosts it resolves to Unfortunately, all errors are still there.

just to be sure, what is the error (in log files)?

can you also add a record to mysql.user for host 'fedora-odl-1' (regardless the wildcard one %) ?

I was having this error in OpenStack Juno, Ubuntu 14.04. Fixed by reinstalling some missing packages on controller node inside (the cinder section) of Openstack Installation.
