Eucalyptus/ubuntu-server-11.04 - instance is running but can't access it

  • 772

I've installed Ubuntu Enterprise Cloud on a server and I'm able to bring up an instance from a image and the instance shows that is running. I see the IPs allocated to that instance but for some reason I can't access it via SSH.

euca-describe-groups shows:

GROUP  admin default default group
PERMISSION admin default ALLOWS tcp 22 22 FROM CIDR 0.0.0.0/0

I'm on the same network as the instance so I'm sure is not an networking problem (like routers, switches etc.).

Any ides?

  1. A few things to check would be

    • Did the instance really start ? ssh to the NC, and try "virsh list", is it listed?
    • A minimum UEC installation requires two nodes, with the NC node having VT support in the CPU. Can you login to the NC node and try "kvm-ok" ? what does that say
    • Can you ssh into the instance from the CLC node ?

  2. I just installed UEC on a single box where the node controller and the cluster controller on the same machine.

    Make sure you create an SSH keypair in order to access the instance:

    euca-add-keypair eucakey > ~/.ssh/eucakey

    Then when you create an instance, create it with that key:

    euca-run-instances -k eucakey emi-54E71716

    Check to make sure that the instance is running:

    euca-describe-instances

    Finally, login to the instance:

    ssh -i ~/.ssh/eucakey ubuntu@
