Pavan, The message is not an error but a warning that a particular python call (Pool.add_listener) is deprecated and will be removed in a future version of the module.

Re: [Openstack] Error while installing Nova (OpenStack-Essex)
Thanks a lot Nathaneal. I am facing problems starting the nova-volume on RHEL. (log message- volume group nova-volumes doesn't exist) There seems to no proper documentation on resolving this for RHEL. I saw this issue being addressed for Fedora in this linkhttp://forums.openstack.org/viewtopic.php?f=16t=611 But am not sure if I can go ahead and use the same steps in RHEL. Anyone has any idea how to resolve this issue ? Any help is appreciated.

Re: [Openstack] Error while installing Nova (OpenStack-Essex)
nova-volume by default uses an LVM volume group (VG) named 'nova-volumes' in which it creates volumes via logical volumes. If that VG doesn't exist you'll get that error and volumes won't work. You can run 'vgs' to list your current volume groups. Nate On Oct 16, 2012 3:01 PM, Pavan Kulkarni pavan.babu...@gmail.com wrote: Thanks a lot Nathaneal.

Re: [Openstack] Error while installing Nova (OpenStack-Essex)
Great. Thanks again for the help Nathaneal :) All the nova services are up except the *nova-consoleauth.* I don't see any particular log for this service . Any idea where to look for the logs ?
