Hello,

How can I check the value of $my_ip?



Thanks,

I notice that in the arp table on the instance, the entry for ip 169.254.169.254 has a wrong mac address, which I don't see existent on both the controller node and the worker node. After I change the entry for ip 169.254.169.254 to map to the real mac address of the controller host(metadata host as well), the curl command works. But, I don't know why the initial wrong mac address gets entered into the arp table in the first place?

Suggest check iptables-save output,Metadata_host default set to $my_ip. if you often switch network,your $my_ip maybe set wrong

    Hello,

    In my essex install on RHEL6, there is a problem with the metadata
    service.
    The metadata service works for instances running on the controller
    node, where
    the nova-api(metadata service) is running. But for the other
    worker nodes,
    the metadata service is intermittent, ie. the instances sometimes
    can get its metadata,
    sometime it fails with errors like:

    $> curl -v http://169.254.169.254:8775/
    * About to connect() to 169.254.169.254 port 8775 (#0)
    *   Trying 169.254.169.254... Connection timed out
    * couldn't connect to host
    * Closing connection #0
    curl: (7) couldn't connect to host

    Any idea where should I start investigating this?

    Thanks,
    Xin
