Re: Instance can't reach dhcp or metadata

  Thread Previous • Date Previous • • Thread Next 
Hi Nicolas,

    You need another interface ( say eth1 UP & running ) .   Configure br100 to use eth1 .



typically your configuration will look like the below ..



/etc/network/interfaces

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
        iface lo inet loopback

# The primary network interface
allow-hotplug eth0
        iface eth0 inet dhcp

auto eth1

auto br100
        iface br100 inet static
        bridge_ports   eth1
        address 10.0.0.1
        netmask 255.255.255.0
        bridge_stp off
        bridge_fd 0



nova.conf will have the following lines too..


--fixed_range=10.0.0.0/24
--network_size=256
--network_manager=nova.network.manager.FlatManager
--flat_interface=eth1
--flat_injected=False
--public_interface=eth0

Subject: [Openstack] Instance can't reach dhcp or metadata

Hi stackers,

I got, using devstack, openstack running. I can launch instance correctly (as seen in horizon state) but the instance can't reach the dhcp or the metadata.

Here the topology (as it should be, but I maybe need to configured otherwise in the conf) of my server (one box only) :

  *   router : 192.168.23.1
  *   server
     *   ip : 192.168.23.5 (with dhcp but always the same)
     *   interface with external (network and internet) : eth0
     *   interface for openvswitch bridge : br100
     *   interface for nova/quantum/melange bridge : br100
  *   openstack
     *   glance with file backend
     *   quantum and melange for networking
     *   openvswitch as plugin

You can find all the config files and log here : https://gist.github.com/2342747.
And networking info below.

Any tips, or pointing misconfiguration will be very appreciated.
