Open Stack

Hi,

I am running devstack (on Ubuntu) on my local machine.  I keep getting this error "Error: Unable to connect to Neutron”  whenever I try to launch an instance using the dashboard.

I debugged further and printed the exception string as part of this message and I see the error "Error: Unable to connect to Neutron.  'FloatingIpManager' object has no attribute ‘is_supported'"

Further, I did the below steps to remove the horizon folder:

./unstack.sh
cd /opt/stack/
rm -rf horizon
cd ~/devstack/
./stack.sh

2015-04-13 13:37:32.099 | + git_timed clone git://git.openstack.org/openstack/horizon.git /opt/stack/horizon
2015-04-13 13:37:32.099 | + local count=0
2015-04-13 13:37:32.099 | + local timeout=0
2015-04-13 13:37:32.099 | + [[ -n 0 ]]
2015-04-13 13:37:32.099 | + timeout=0
2015-04-13 13:37:32.099 | + timeout -s SIGINT 0 git clone git://git.openstack.org/openstack/horizon.git /opt/stack/horizon
2015-04-13 13:37:32.109 | Cloning into '/opt/stack/horizon'...

I  noticed that an older version of the below file is being pulled where  FloatingIpManager doesn’t have is_supported method (when I do git clone git://git.openstack.org/openstack/horizon.git /opt/stack/horizon manually, the latest version is being pulled)

/opt/stack/horizon/openstack_dashboard/api/neutron.api

class FloatingIpManager(network_base.FloatingIpManager):

    […]
    def __init__(self, request):
        self.request = request
        self.client = neutronclient(request)

   def is_simple_associate_supported(self):
        # NOTE: There are two reason that simple association support
        # needs more considerations. (1) Neutron does not support the
        # default floating IP pool at the moment. It can be avoided
        # in case where only one floating IP pool exists.
        # (2) Neutron floating IP is associated with each VIF and
        # we need to check whether such VIF is only one for an instance
        # to enable simple association support.
        return False

   << no "is_supported" method >>

def get_ipver_str(ip_version):
    """Convert an ip version number to a human-friendly string."""
    return IP_VERSION_DICT.get(ip_version, '')

Please let me know what I am missing here.

Thanks,
Ganesh
