Hi all,

I followed this how to: https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/blob/OVS_MultiNode/OpenStack_Grizzly_Install_Guide.rst exaclty as it says.

However I can't ping the vm, nor ssh it. Instead I can ping the interface of the router and the default gateway.

Any help will be appreciated as I've been a week trying to connect to my vm.

Greetings,

Lucio

Hi Lucio, I can help you out with your issue because I was struggling with similar one some time ago and now it works fine. What do you get from VM's console output when booting this cirros image during network addressing step? Do you have any warnings/errors in quantum openvswitch plugin, nova-compute or syslog on your compute node? Also I would like to see the output of: 1)ifconfig of cirros's VM tap device from compute node 2)ovs-vsctl show from compute node 3)grep ovs /var/log/syslog and grep dns /var/log/syslogfrom compute node 4)dnsmasq --version from compute node

Check this post for some useful troubleshooting: http://lorinhochstein.wordpress.com/2013/05/29/the-challenge-of-the-network/

Cheers, Peter

Hope you can write me back soon!

Hello Lucio, I've noticed that your openvswitch is 1.4.0 - are you sure you have downloaded it from grizzly's source list?

Regarding these permissions errors - make sure you are using openvswitch from grizzly's source, in my case it's 1.4.2 for 3.2.0-23-generic kernel, reboot all nodes and try to boot this cirros image again. I want to see if these permission denied errors will go away - if not try to grant quantum user full access:

`root@compute:~# cat /etc/sudoers.d/quantum_sudoers Defaults:quantum !requiretty

quantum ALL = (root) NOPASSWD: /usr/bin/quantum-rootwrap

quantum ALL=NOPASSWD: ALL root@compute:~# service quantum-plugin-openvswitch-agent restart`

Below you can see that it is working:

Hello Peter,

I updated the repos and reinstalled "openvswitch-switch openvswitch-datapath-dkms"

Still have no luck. No IPs assigned :(

Write me back soon!

Cheers!

Lucio, First check /etc/sudoers - it should have this exact line commented: `root@compute:~# grep includedir /etc/sudoers

includedir /etc/sudoers.d`

Change sudoers file for quantum like this: `root@compute:~# cat /etc/sudoers.d/quantum_sudoers Defaults:quantum !requiretty

quantum ALL = (root) NOPASSWD: /usr/bin/quantum-rootwrap

quantum ALL=NOPASSWD: ALL`

Then enable shell access for quantum's user: root@compute:~# grep quantum /etc/passwd quantum:x:106:112::/var/lib/quantum:/bin/false root@compute:~# usermod -s /bin/bash quantum

Now we can check sudo rights for quantum: root@compute:~# su - quantum quantum@compute:~# sudo ovs-vsctl show 6ec2edef-7839-4320-9922-14561a958dd0 Bridge br-int Port br-int Interface br-int type: internal Port patch-tun Interface patch-tun type: patch options: {peer=patch-int} Bridge br-tun Port br-tun Interface br-tun type: internal Port patch-int Interface patch-int type: patch options: {peer=patch-tun} Port "gre-2" Interface "gre-2" type: gre options: {in_key=flow, out_key=flow, remote_ip="10.28.8.89"} ovs_version: "1.4.2"

Finally disable shell access as before: quantum@compute:~$ exit root@compute:~# usermod -s /bin/false quantum

Restart compute services: root@compute:~# service openvswitch-switch restart root@compute:~# service quantum-plugin-openvswitch-agent restart root@compute:~# service nova-compute restart

Check the logs and give me some good news :)

Peter

Hi Peter,

look at this:

root@compute:/home/latechco# su - quantum quantum@compute:~$ ovs-vsctl show

After tail -n 100 openvswitch-agent.log there are no entries. No odd entries in any log.

Write me back soon!

Hi Peter,

I can ping the vms private address (50.50.1.2) from the controller node too. But ping to another private ip from another vm (50.50.1.4) just stays still:

latechco@controller:~$ ping 50.50.1.2 PING 50.50.1.2 (50.50.1.2) 56(84) bytes of data. 64 bytes from 50.50.1.2: icmp_req=1 ttl=107 time=200 ms 64 bytes from 50.50.1.2: icmp_req=2 ttl=107 time=206 ms 64 bytes from 50.50.1.2: icmp_req=3 ttl=107 time=200 ms 64 bytes from 50.50.1.2: icmp_req=4 ttl=107 time=200 ms 64 bytes from 50.50.1.2: icmp_req=5 ttl=107 time=202 ms ^C --- 50.50.1.2 ping statistics --- 6 packets transmitted, 5 received, 16% packet loss, time 5002ms rtt min/avg/max/mdev = 200.577/202.273/206.580/2.319 ms latechco@controller:~$ ping 50.50.1.4 PING 50.50.1.4 (50.50.1.4) 56(84) bytes of data.

Write me back soon!

You won't be able to reach the subnet 50.50.1.0/24 outside compute node. Also You need to give source interface for ping because without it You are reaching 50.50.1.2 from the internet:

Hi Peter.

ping to interfaces didn't work:

Thanks again!

Write me back soon!

Remember to use creds for user_one and show me root@controller:~# nova list root@controller:~# nova secgroup-list root@controller:~# nova secgroup-list-rules default We need to check whether You added rules for icmp traffic ;) If this won't help - delete all instances, reboot all nodes and boot cirros again. I want to see if it gets IP address this time from console output. Good luck!

Peter

Hi Peter,

here's the data before the three nodes reboot:

Here's the data after the three nodes reboot:

Still no luck :(

Peter,

thank you very much for your support.

Today I just reinstalled the three servers and had an issue with openvswitch on the Network node.

After all what I did was not to upgrade the Network node which was causing me issues with openvswitch and finally I can ping and ssh to my cirros instance.

Thank you very much again!

Lucio

Nice to hear that Lucio - I'm glad I could help :) I think we can close this issue now.

Cheers, Peter

@moss2k13 , So do you suggest to upgrade all nodes ubuntu with : deb http://archive.gplhost.com/debian grizzly main deb http://archive.gplhost.com/debian grizzly-backports main

at the moment I have

openvswitch-switch | 1.4.0-1ubuntu1.5 | http://gb.archive.ubuntu.com/ubuntu/ precise-updates/universe amd64 Packages openvswitch-switch | 1.4.0-1ubuntu1 | http://gb.archive.ubuntu.com/ubuntu/ precise/universe amd64 Packages openvswitch | 1.4.0-1ubuntu1 | http://gb.archive.ubuntu.com/ubuntu/ precise/universe Sources openvswitch | 1.4.0-1ubuntu1.5 | http://gb.archive.ubuntu.com/ubuntu/ precise-updates/universe Sources

I have 2 compute / 1 net / 1 cont:

I can ping vm each other, I can ssh from outside , inside the vm I can ping google and bbc but I can't do apt-get update from example a vm with ubuntu cloud image or not able to surf from a vm instace with ubuntu desktop . so I think is a problem with DNs .

I have notice that : all cat /var/log/quantum/openvswitch-agent.log is clean but just the node that I restart the service "quantum-plugin-openvswitch-agent"and the other two node : get some error :

ERROR [quantum.agent.linux.ovs_lib] Unable to execute ['ovs-vsctl', '--timeout=2', 'add-port', 'br-tun', 'gre-3']. Exception: Command: ['sudo', 'quantum-rootwrap', '/etc/quantum/rootwrap.conf', 'ovs-vsctl', '--timeout=2', 'add-port', 'br-tun', 'gre-3'] Exit code: 1 Stdout: '' Stderr: 'ovs-vsctl: cannot create a port named gre-3 because a port named gre-3 already exists on bridge br-tun\n'

then depend wherre I restart the service I get gre-1 or gre-2

what else I need to check ?

Hello All, I am struggling a week...to configure the openstack in 4 nodes but cannot ping instances, I can create instances router etc but VMs does not get an ip

Is it related with ovswitch? or quantom.. I dont have any errors in the log files.. Is it related to the kernel?

please I need some help!

Hello, This issue has been closed Stelio - investigate similar issues, below I will give you some hints: 1)make sure you enabled dhcp during subnet creation, 2)make sure you don't have errors in /var/log/quantum/openvswitch-agent.log - check https://github.com/mseknibilel/OpenStack-Grizzly-Install-Guide/issues/133#issuecomment-27088805 3)make sure you have gre tunnels up and running using ovs-vsctl show command If after that you still have problems you had to missed something during installation - mseknibilel's guide works.

Good luck! Peter
