I have installed Openstack grizzly on a single node.

I have 2 network interfaces

  • external connection (eth0)

    eth0      Link encap:Ethernet  HWaddr 00:50:56:b5:35:3c
              inet addr: Bcast: Mask:
              RX bytes:4763669 (4.7 MB)  TX bytes:3566739 (3.5 MB)
  • internal connection (eth1)

    eth1      Link encap:Ethernet  HWaddr 00:50:56:b5:35:3d
              inet addr:  Bcast:  Mask:
              RX bytes:122430862 (122.4 MB)  TX bytes:46150 (46.1 KB)

I am using linux bridge linuxbridge_conf.ini

tenant_network_type = vlan
network_vlan_ranges = physnet1:1000:2999
sql_connection = mysql://quantum:quantum@localhost/quantum
reconnect_interval = 2

physical_interface_mappings = physnet1:eth1

polling_interval = 2

firewall_driver = quantum.agent.linux.iptables_firewall.IptablesFirewallDriver

I am having problems while setting up networks. What should be my network architechture so that I can also provide internet connection to the vms.

Any help will be appreciated

You didnt tell what problems you are facing.

If this is a single node, you need not bother about eth1 (interface for private network). If there are multiple nodes, you need to configure the switch port for (eth1) with appropriate vlan tags.
