Re: Grizzly G3+RC1 - Quantum DHCP problem...

  Thread Previous • Date Previous • • Thread Next 
It seems be about sudo.
to create one sudo file under /etc/sudoers.d
mine is: nova_sudoers:
Defaults:gongysh !requiretty
gongysh ALL = (ALL) NOPASSWD: ALL

Hi!
I just rollback to the default namespace options, my Instance now get its IP without problem. 

But, the message from my first e-mail on this thread, still persist...

I tried to enable quantum metadata proxy stuff but, nothing changes...

The following error keeps rolling at my /var/log/quantum/dhcp-agent.log:

---
...

 I tried everything I could... But this message persist...

 The namespaces are enabled, look:

ip netns exec qdhcp-21a39c11-03fd-4e2e-b7a0-94eee95f5f91 ip r
10.33.14.0/24 <http://10.33.14.0/24> dev tapeb27823a-5e proto kernel scope link src 10.33.14.2 

 What can I do?

Tks,
Thiago

    After disabling namespaces, with:

    `allow_overlapping_ips = False' in quantum.conf

    and with:

    `use_namespaces = False' in /etc/quantum/dhcp_agent.ini

     The previous error message dissapear but, My Instance
    isn't getting its IP via DHCP now... Weird thing is that it was
    working couple minutes ago, without disabling
    namespaces explicitly...

     If I add the Instance IP by hand, I can reach the Internet /
    gateway from it.

     I'm finishing my Grizzly Quantum Single Flat PoC environment,
    planning to publish a nice guide soon!

     I appreciate any help!

    Tks!

         Tips?

         It is a fresh installation to test Grizzly...

         I'm not using GRE or L3, only Quantum Single FLAT... With
        Folsom and previous Grizzly my Quantum was fine...

        Tks,
