Open Stack

The only other thing to check is if your network parameters such as netmask
is correct.

Hi Akash,

I made the changes you pointed out, but it doesn't seem to make any
difference. I am in the same network as the server but still not able to
ping or ssh to the vm. I double checked my networking rules and have
configured tcp and icmp properly. Don't really know where this might be
breaking. Is there anything else I can do to debug this issue?
I also have a installation guide document that I followed, if you want it
for reference.

  Hi,

  I have deployed Kilo using Packstack on CentOS , but I am having troubles
  accessing the VM's that I spawn , through the public IP's that they are
  assigned to them.

  I created my network as follows:

  CREATE NETWORK FOR OPENSTACK
        1. a. neutron router-gateway-clear router1 (neutron
        router-gateway-list)
        b. neutron subnet-delete public_subnet
        c. neutron net-delete public
        d. neutron router-interface-delete router1 private_subnet
        e. neutron subnet-delete private_subnet
        f. neutron net-delete private
        g. neutron router-delete router1
        2. a. neutron router-create router1
        b. neutron net-create private
        c. neutron subnet-create --name private_subnet private
        192.168.0.0/16 --allocation-pool
        start=192.168.0.0,end=192.168.255.250
        d. neutron router-interface-add router1 private_subnet
        3. a. neutron net-create public --router:external=True
        //(neutron net-create public --router:external)
        b. neutron subnet-create public 10.16.37.0/24 <set for your n/w>
        --name public_subnet --enable_dhcp=False --allocation-pool
        start=10.16.37.230,end=10.16.37.250 <make sure that it will not
        conflict with other IP address> --gateway=10.16.37.1 <your n/w
        gateway>

        c. neutron router-gateway-set router1 public


  Also I made changes in the ifcfg-br-ex file and ifcfg-<my network> file
  in /etc/sysconfig/network-scripts.

  The Changes were as follows:

  ifcfg-br-ex
  DEVICE=br-ex
  BOOTPROTO=static
  IPADDR=<your workstation IP address> e.g 10.16.37.221
  NETMASK=255.255.255.0
  DNS1=<your n/w DNS1> e.g 10.16.25.13
  DNS2=<your n/w DNS2> e.g 10.16.25.15
  BROADCAST=10.16.37.255
  GATEWAY=10.16.37.1
  NM_CONTROLLED="no"
  DEFROUTE=yes
  IPV4_FAILURE_FATAL="yes"
  IPV6INIT=no
  ONBOOT=yes
  TYPE=OVSIntPort
  OVS_BRIDGE=br-ex
  DEVICETYPE=ovs

  ifcfg-p2p1
  DEVICE=p2p1 <change with your device name>
  # HWADDR=00:22:15:63:E4:E2
  ONBOOT="yes"
  TYPE="OVSPort"
  DEVICETYPE="ovs"
  OVS_BRIDGE=br-ex
  NM_CONTROLLED=no
  IPV6INIT=no




  There is also a proxy in the network and so for that, I installed by "
  packstack --allinone --provision-demo=n
  --provision-all-in-one-ovs-bridge=n".

  Could someone suggest me a reason as to why i might be facing issues or
  probably where I can look to debug this issue.

  Thanks,
  Dhvanan Shah_______________________________________________
