    Hi Veera,

    I forgot to mention that I have already configured the security
    groups  for bothe ssh/icmp, but this did not help.

    Hi Johanna,

    Using Security Groups you can ping and SSh to your VM.

    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@localadmin:~# ovs-vsctl show

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

    Bridge br-tun

                Interface "vnet2"

            Port "tap2fd9694b-51"

                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,

    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?

    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.
