yup.. its running but there are no availability zones.

2014-05-12 04:08:15 -0600 commented answer Devstack- Not able to launch an instance

I am not able to find log files of nova. I checked in /var/log and there are no nova, neutron folders. Where are the logs available if i install during devstack? In "system info" of Admin Panel, i can see all services are enabled(nova-compute, nova-computev3, neutron-network and others). All network agents are also up and running. Please note that i did not have any errors during installation of devstack. It is only the instance creation which is encountering the problem.

2014-05-12 02:01:26 -0600 asked a question Devstack- Not able to launch an instance

Hi, I installed openstack using Devstack environment. But now i am not able to launch an instance. When i do so no availability zones are available plus it gives an error without any description when i launch it. I am not able to view any openstack services logs (nova, neutron etc.). In stack.sh.logs also i am not able to view anything. Is there any error?? I am not able to understand anything. Please help me what i am doing wrong.. I checked in var/log/syslog but i found nothing. Also tell me about local.conf, currently i am using localrc. Will it be sufficient? or should i use some local.conf by putting stackrc and localrc files together in it??? Please help.

i had tried the flat network also but it still issues the same problem..

2014-04-08 04:53:24 -0600 asked a question DHCP discover request does not reach controller node.

I have a 2 node set with single interface. The interface is on the 192.168.10.0/24 subnet. One is with ip 160 and the other with 161

I am trying to create a flat network using neutron.

On the controller/network node, In the ovs_neutron_plugin.ini file:

Tenant_network_type //(commented )

Network_vlan_ranges = physnet1

Bridge_mappings = physnet1:br-ex

$ovs-vsctl show

Bridge br-int

     Port int-br-ex
       Interface int-br-ex

     Port br-int
        Interface br-int
            type: internal

   Tap interface “tapxxx”

Bridge br-ex
    Port br-ex
        Interface br-ex
            type: internal
    Port phy-br-ex
        Interface phy-br-ex
    Port "eth0"
        Interface "eth0"

The compute code has the same config as above, except the ‘Tap’ interface’ which is created by the dnsmasq process.

eth0 on both nodes are in promiscuous mode and attached to br-ex

I created a tenant, network and a subnet 198.168.10.0/24. I was able to spin a VM successfully on the compute node but it fails to allocate the IP address.

While creating the network the type was specified as ‘flat’

The horizon front-end displays the IP address as successfully allocated but it is not configured on the VM (ifconfig on VM). Dnsmasq is created correctly.

Using wireshark, on the compute node, I can see that the discover request being sent from the VM hardware address to br-int and also to phy-br-ex. However the interface, br-ex and eth0 which is attached to br-ex, does not receive the Discover request.

What happens to the connectivity from phy-br-ex to br-ex? Why does the discover request not show in br-ex and eth0 while it shows in br-int, int-br-ex and phy-br-ex.

Why does horizon show it as being allocated. Does the DNSmasq process allocate it without waiting for the discover request?

Is there anything wrong in the config files? Should we specify tenant_network? I left it commented for the flat network. The only difference from the guides is that we use the notification_driver = neutron.openstack.common.notifier.rpc_notifier instead of notification_driver = neutron.openstack.common.notifier.rabbit_notifier and control_exchange is default – commented.

I do not think it makes any difference to the network part but if someone could explain the reason for packets not showing in br-ex while it shows in phy-br-ex, it would be helpful.
