ohai ipaddress returns loopback address on servers virtualized through OpenVZ

Details

  • Type: Bug Bug
  • Status: Open Open
  • Priority: Major Major
  • Resolution: Unresolved
  • Affects Version/s: 0.5.8, 6.16.0
  • Fix Version/s: 0.6.0
  • Component/s: Network
  • Labels:
    None
  • Environment:

    Ubuntu (seems to affect Debian as well) virtualized on OpenVZ

Description

Ohai returns 127.0.0.1 for "ohai ipaddress" because OpenVZ sets up venet0 as 127.0.0.1. The actual IP for the box is always setup as an alias like venet0:1

Maybe Ohai should check if the IP found for the default route is 127.0.0.1, and if so, see if another IP can be found from "hostname -i" or another method. If not, then go ahead and return 127.0.0.1.

Here is more info from the OpenVZ forums: http://forum.openvz.org/index.php?t=msg&goto=4762&

This happens again (still?) on ohai version 6.16.0:

  1. ohai --version
    Ohai: 6.16.0
  2. ohai virtualization { "system": "openvz", "role": "guest" }
  3. ohai ipaddress
    [
    "127.0.0.1"
    ]
