Open Stack

Hi Salvatore,

 

I am using Quantum with OVS-plugin. My quantum files are attached.

 

I have done my configuration by following the instructions by E. Macchi
(includes a tenant internal network and a provider network) and Quantum
admin quide (folsom). I have a single node installation with one
interface eth0 and ubuntu 12.04. The OVS is configured like this:

 

ovs-vsctl add-br br-int

ovs-vsctl add-br br-ex

ovs-vsctl br-set-external-id br-ex bridge-id br-ex

ovs-vsctl add-port br-ex eth0

 

I am able to start VMs in both the tenant network and provider network,
they are getting IPs and they become active. The only problem is that I
am not able to connect to them anyhow (no ssh, no ping...)

ovs-vsctl looks like this:

 

root at localadmin:~# ovs-vsctl show

86f47d37-93b0-4037-a988-1667f85d7c10

    Bridge br-tun

        Port br-tun

            Interface br-tun

                type: internal

        Port patch-int

            Interface patch-int

                type: patch

                options: {peer=patch-tun}

    Bridge br-ex

        Port br-ex

            Interface br-ex

                type: internal

        Port "eth0"

            Interface "eth0"

        Port "qg-89636625-f4"

            Interface "qg-89636625-f4"

                type: internal

    Bridge br-int

        Port patch-tun

            Interface patch-tun

                type: patch

                options: {peer=patch-int}

        Port "vnet1"

            tag: 6

            Interface "vnet1"

        Port "vnet2"

            tag: 1

            Interface "vnet2"

        Port "tap2fd9694b-51"

            tag: 1

            Interface "tap2fd9694b-51"

                type: internal

        Port "vnet0"

            tag: 1

            Interface "vnet0"

        Port br-int

            Interface br-int

                type: internal

    ovs_version: "1.4.0+build0"

 

Maybe there is something wrong in my configuration? What are the best
troubleshooting tools in this case?

 

Best regards,

Johanna

Hi Johanna,

 

are you running Openstack with Quantum or nova-network? In the former
case, which plugin are you using?

If you are using nova-network, which network manager are you using?

Hi Daniel,

 

Did you solve your problem? If yes, what was the solution? I am
interested because I have similar issues in my setup.

So, can anyone help me?

When viewing the console-log of a VM, I noticed the following:

 

"

Starting network...

udhcpc (v1.18.5) started

Sending discover...

Sending discover...

Sending discover...

No lease, failing

WARN: /etc/rc3.d/S40-network failed

"

Hello. I installed OpenStack via devStack, and I've noticed I am unable
to SSH, or even ping, to any VM I launch. I've already added both rules
to the default security group (port 22 for SSH, and ICMP rule). I hope
someone can help me, thanks in advance.

 

P.S.:

-I am not very experienced with all of this, so if you ask me for the
output of some command or log, please specify the file path/command;

-I had a thread with a similar question on this list, but I deleted it
from my email unintentionally.
