Hi Ashutosh,

In reply to your query on Quantum CLI errors on Grizzly

I have similar error when running quantum net-create private as per step
13.1 Create a private network according to
https://fedoraproject.org/wiki/Packstack_to_Quantum

My System information:

RHEL 6.4
Installation done following the Red Hat RDO @
http://openstack.redhat.com/Quickstart, you may go deep into looking my
post on installing RDO for RHEL @
http://openstack.redhat.com/forum/discussion/98/my-redhat-version#Item_4

Workaround:

1) Disable selinux
2) Disable firewall

Above steps might not be the root cause.

Looking into /var/log/quantum

tail /var/log/quantum/l3-agent.log
2013-05-09 11:07:38    ERROR [quantum.openstack.common.rpc.impl_qpid]
Unable to connect to AMQP server: [Errno -2] Name or service not known.
Sleeping 16 seconds

It is said that "Unable to connect to AMQP server"

1) check the qpid service whether it is running or not

# netstat -ntupl |grep 5672
tcp        0      0 0.0.0.0:5672                0.0.0.0:*
LISTEN      2671/qpidd
tcp        0      0 :::5672
:::*                                LISTEN      2671/qpidd

2) check your /etc/quantum/quantum.conf
search for qpid_hostname, for example my configuration

qpid_hostname = rdo

the program look for qpid service on host rdo instead of localhost,
Check whether you can ping the hostname, e.g ping rdo, if it is not then
resolve it via /etc/hosts file

127.0.0.1   localhost localhost.localdomain localhost4 rdo

3) This might also not be the cause, but I did change. Check your
/etc/nova/nova.conf
#grep rabbit /etc/nova/nova.conf

rabbit_host=192.168.204.134

re run the quantum net-create step.

I also able to create network and routers in dashboard

Hope this helps.*

Thank You,
