[3] | Configure Networking. The follows is for the case you use legacy nova-network function. But if you use Neutron Networking function, Refer to here to configure it. Anyway, legacy nova-network function is officially not recommended. |
[root@dlp ~]#
vi /etc/nova/nova.conf # add follows in [DEFAULT] section network_driver=nova.network.linux_net libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtGenericVIFDriver linuxnet_interface_driver=nova.network.linux_net.LinuxBridgeInterfaceDriver firewall_driver=nova.virt.libvirt.firewall.IptablesFirewallDriver network_api_class=nova.network.api.API security_group_api=nova network_manager=nova.network.manager.FlatDHCPManager network_size=254 allow_same_net_traffic=False multi_host=True send_arp_for_ha=True share_dhcp_address=True force_dhcp_release=True # specify nic for public public_interface=eth0 # specify any name you like for bridge flat_network_bridge=br100 # specify nic for flat DHCP bridge flat_interface=lo |
[4] | Start Nova Service. If you don't use legacy nova-network, exclude the word "network" below. If you separate Compute Nodes, exclude the word "compute" below, too. |
