Re: [openstack-dev] [OpenStack-Dev][DevStack][Neutron] devstack install - need help on local.conf settings

2017-06-02 Thread Ganpat Agarwal 
Hi Nidhi,

Try this :

*Set up the network environment on the host so that devstack VMs can access
the external world.*

*sudo bash*
*echo 1 > /proc/sys/net/ipv4/ip_forward*
*echo 1 > /proc/sys/net/ipv4/conf/INTERFACE/proxy_arp*
*iptables -t nat -A POSTROUTING -o INTERFACE -j MASQUERADE*

*These command will make sure that network traffic will be correctly routed
in and out of the devstack VMs.*
*The ip_forward and proxy_arp changes will be reset when the machice
reboots. You can make these changes permanent by editing /etc/sysctl.conf
and adding the following lines:*

*net.ipv4.conf.INTERFACE.proxy_arp = 1*
*net.ipv4.ip_forward = 1*

*Replace INTERFACE with ethernet interface of your virtual box.*

Hope it will work as it works always for me.

Regards,
Ganpat

Re: [openstack-dev] [OpenStack-Dev][DevStack][Neutron] devstack install - need help on local.conf settings

2017-06-02 Thread nidhi.h...@wipro.com 
Hello all,

I am using http://paste.openstack.org/show/595339/ as my local.conf.

I wanted to understand :- Which interface should we put as value in
PUBLIC_INTERFACE in local.conf.


Reason why I am asking this is,

Once, I installed OpenStack using DevStack, on my linux VM on
VirtualBox - I used PUBLIC_INTERFACE value as eth0
and
I configured only one network adapter on VM in NAT mode.

Later on I faced lot of networking problems in that OpenStack VM.
Internet wasn't accessible suddenly and many other probs.

I debugged and somehow found eth0 was added in
One ovs-bridge and if I remove eth0 from that bridge -
only then internet in my VM used to work well.

Then I doubted PUBLIC_INTERFACE value in local.conf
is something I should setup correctly..

Could not find much help on this from google.

Can someone please enlighten?

Thanks
Nidhi

Hi Andreas,



As in between you suggested to try with default devstack

neutron config params. I tried that i set no config option

for neutron part all default.



This local.conf is working well..



for others who are facing problem pasting working local.conf here

http://paste.openstack.org/show/595339/



Attaching too.



Thanks

Nidhi

Andreas,



I require nothing specific from neutron side.

Just a basic working setup from neutron side

because my work is mostly on storage side of

OpenStack.



Can you please suggest a working configuration

if  tried recently.



Thanks

HI Andreas,



Thanks for your reply.



I have no specific reason for using this network configuration in local.conf.

I have only basic knowledge of these config options even.

This local.conf network configurations used to work well with earlier

devstack openstack versions. So i did not change it..

Just this time its creating trouble.



I have not created any ovs bridge manually  before running devstack.

just created this local.conf and ran ./stack.sh in devstack folder.



Can you please suggest changes if i have not created ovs-bridge manually.



At present my settings are - from local.conf - for reference -
FIXED_RANGE=10.11.12.0/24
NETWORK_GATEWAY=10.11.12.1
FIXED_NETWORK_SIZE=256

FLOATING_RANGE=10.0.2.0/24
Q_FLOATING_ALLOCATION_POOL=start=10.0.2.104,end=10.0.2.111
PUBLIC_NETWORK_GATEWAY=10.0.2.1
HOST_IP=10.0.2.15

PUBLIC_INTERFACE=eth0

Q_USE_SECGROUP=True
ENABLE_TENANT_VLANS=True
TENANT_VLAN_RANGE=1000:1999
PHYSICAL_NETWORK=default
OVS_PHYSICAL_BRIDGE=br-ex


Q_USE_PROVIDER_NETWORKING=True
Q_L3_ENABLED=False

PROVIDER_SUBNET_NAME="provider_net"
PROVIDER_NETWORK_TYPE="vlan"
SEGMENTATION_ID=2010

** This mail has been sent from an external source **

Without looking into the details

you're specifying
Q_USE_PROVIDER_NETWORKING=True
in your local.conf - usually this results in the creation of a single
provider network called "public". But the manila devstack plugin seems
not to be able to deal with provider networks as it's expecting a
network named "private" to be present.


Why are you using provider networks? Just for sake of VLANs? You can
also configure devstack to use vlans with the default setup. This has
worked for me in the past - results in a private network using vlans
(assuming you have created ovs b bridge br-data manually):


OVS_PHYSICAL_BRIDGE=br-data
PHYSICAL_NETWORK=phys-data

ENABLE_TENANT_TUNNELS=False
Q_ML2_TENANT_NETWORK_TYPE=vlan
ENABLE_TENANT_VLANS=True
TENANT_VLAN_RANGE=1000:1000
