OpenStack installation 4 NIC ubuntu-14.04 and network details configuration

Four network cards:

Network 1: The physical machine is connected to the virtual machine, for the host-only type, which is used primarily to manage the network, it's DHCP off.

Network 2:open Vswitch occupies the network, is also the host-only type

There are a number of storage components in the network 3:openstack that deliver a large amount of data, which is best transmitted using a single network (which is also recommended in real-world environments), and the type is host-only

Network 4: specifically to connect to an Internet network, for NAT type

First download VirtualBox (compared to the VMware Workstation Vitualbox lighter and more functional), the following I choose is a more stable order builds

We installed the virtual machine in VirtualBox to learn OpenStack to install successfully, it has 4 different functions of the network card, 3 disk, and can connect the external network

It is best to use only eth0 addresses for remote connections, although eth1 and eth2 addresses can also be telnet, but the two NICs are reserved for use by other components.

Eth1 is used for open Vswich.

Eth2 is reserved for use in other group prices for Opnestack

To configure problems encountered in the network:

At first I was setting up VirtualBox host-only Ethernet Adapter #2 and VirtualBox host-only Ethernet Adapter #3的IP的IP时, The IP settings are 192.168.60.1 and 192.168.61.1, i.e. automatically distributing 192.168.60.2-192.168.60.254 and 192.168 to Eth1 and eth2 two NICs respectively. The IP of the 61.2.-192.168.61.254 network segment, which is the gateway of both eth1 and eth2 and their dhcp-server address

However, when you create or restart the virtual machine, you will immediately be prompted to prompt windows to detect the IP conflict with a host (note that this is not the other virtual machine you installed, but the entire local area network of your environment where someone's IP and you conflict, This is I have changed VirtualBox host-only Ethernet Adapter #2 and VirtualBox host-only Ethernet Adapter #3的IP不下20 times after the conclusion, A variety of different network segments of the private IP network segment are set up, really can not find conflict, and finally fortunately, in the company's configuration found 172.16.66.1 and 172.16.88.1 network segment can be used, and this experiment is based on the successful configuration of the company to do.

But at this time I in the home configuration is not so fortunate, still did not resolve the IP conflict, finally can only put VirtualBox host-only Ethernet Adapter #2 and VirtualBox host-only Ethernet Adapter # 3 of the IP of DHCP off, let it only do eth1 and Eth2 Gateway, and after the virtual machine is turned on the static configuration of the two network cards in/etc/network/interfaces IP (home LAN IP appears to be occupied. After all, DHCP needs to be assigned an entire network segment of IP, not just a single IP.

When you configure the Host-only NIC to run in CMD Ipconfig/all by the first

Suddenly become this, that means the IP conflict, the preferred IP is the windows to you reconfigure Microsoft's own network segment 169.254.0.0 IP, and the original IP into a copy! This way your virtual machine's eth1 and eth2 are ping different from your own gateway

Originally wanted to try to shut down the IP auto configuration of windows, also searched on the internet is mainly the following similar method:

Workaround for automatic configuration of IPv4 (Win7 system):

Run as Administrator cmd.exe

Input: netsh winsock reset catalog press ENTER

Input: netsh int ip reset reset.log Press ENTER

Restart

Then fill in the IP address, subnet mask, gateway, OK

However, there is no egg to use, set up after restarting, with the IP, the start of the virtual machine, but also for eth1 and eth2 to reassign the IP, or conflict, or will be automatically configured, but also in the control Panel directly shut down the Windows DHCP service, But I think that if it is turned off certainly even the internet is a problem, so really can't solve first set to static bar, estimated no one than my back ^_^.

The feeling is that VirtualBox is indeed simpler and smaller than the VMware Workstation, with a system from configuration to 10 minutes after installation ^_^

At the end of this experiment, the next time the OpenStack component installation will be done directly

Cut out so many pictures. Tired...
