2017-01-12 05:47:01 -0500 asked a question tacker user_data not working for OpenWRT image

Following tosca template is not working as expected for OpenWRT image. It is not updating the /etc/hosts file. In contrast when I am using cirros image instead, it is working perfectly.

Any help regarding would be appreciated.

2017-01-11 00:36:35 -0500 answered a question tacker vnf-create: how to customize my VNF ?

Hello William. Can you please tell if you are still facing issues related to VNFs ?

2017-01-11 00:33:48 -0500 asked a question How to create management network for tacker ?

I have Devstack Single Node (Mitaka version) installed with tacker component enabled. Many documents talks about the Tacker Management Network through which it provisions the VNFs it had spawned, enable or disable the functionality of VNF. Can anyone help me how to create this management network.

2017-01-04 05:02:16 -0500 commented question Count number of hosts per network

Hi Bernd, this command gives all nodes. What I am trying to do is count hosts attached to a specific network-id. The process of using openstack server list --all-projects would be very inefficient, I think.

2017-01-04 01:33:37 -0500 asked a question Count number of hosts per network

I am trying to calculate number of hosts connected to a specific network in openstack. Is there any efficient way to do so ?

2016-08-26 00:22:09 -0500 asked a question tacker vnf-update results in error state of a VNF

I am creating openwrt VNF through the following command:

tacker vnf-create --vnfd-id <id of openwrt vnf-d> --name openwrt_1

This vnfd have three connecting points which results in creation of eth0, eth1, eth2. This vnf is getting in Active mode,but when I am trying to update this vnf by following command,

stack@abhilash-VirtualBox:~$ tacker vnf-update --config-file tosca-cirros-firewall-update.yaml     c1fe94f6-4eb1-49b1-9eaa-0e56ded15a29
Updated vnf: c1fe94f6-4eb1-49b1-9eaa-0e56ded15a29

this says that vnf updated, but results in leaving vnf in error state with reason saying 'VNF configuration failed'.

tosca-cirros-firewall-update.yaml file looks like:

      network: |
       package network
        config interface 'loopback'
            option ifname 'lo'
            option proto 'static'
            option ipaddr ''
            option netmask ''
        config interface 'lan'
            option ifname 'eth0'
            option type 'bridge'
            option proto 'dhcp'
            option ip6assign '60'
        config interface 'wan'
            option ifname 'eth1'
            option proto 'dhcp'
        config interface 'wan6'
            option ifname 'eth1'
            option proto 'dhcpv6'
        config interface 'wan'
            option ifname 'eth2'

        config interface 'wan6'
            option ifname 'eth2'
            option proto 'dhcpv6'
        config globals 'globals'
            option ula_prefix 'fdb3:e323:e93b::/48'

Kindly suggest, where am I going wrong. Thanks in advance.

Any answer why is it so, or what else is needed to be done in local testing.

My single node openstack devstack setup is currently running perfectly, but when I change hostname of my system i.e. I made changes in /etc/hosts and /etc/hostname to set a new hostname. After rebooting system setup is running with error of oslo messaging saying

ERROR oslo.messaging._drivers.impl_rabbit [-] AMQP server closed the connection. Check login credentials: Socket closed

On running nova list error shows up saying

ERROR (ClientException): The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-c4251e32-c59e-4ebf-aad1-9f13236f41a1)

Any idea what is potential solution to this.

PS: If I revert back the changes, it start running perfectly.

2016-02-24 10:13:28 -0500 asked a question Traceroute floating IP of VM hosted by openstack shows 0 hops, but we have a virtual router which is connecting external network and tenant network.

I have a doubt, when I am pinging instances hosted by openstack which is in tenant network( and I have a virtual router connecting tenant network with external network( I have floating IP associated with each instances. This states that there is one hop(router) between my external PC and instance in tenant network, therefore traceroute should show 1 hop when pinging instance, but its showing 0 hops.

Any explanation to this ?
