Hi Dhvanan,
Couple of changes are needed in the ifcfg-br-ex file. Please check the
changes I made in below.
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=OVSBridge
OVS_BRIDGE=br-ex
DEVICETYPE=ovs

Subject: [Openstack] External network Issues
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_______________________________________________
