使用vagrant设置集群

我想使用Vagrant创建一个包含4个CentOS VM的集群 . 我在Widnows机器上安装了Vagrant和VirtualBox，下载了CentOS 64盒并创建了集群 . Steps ：

• 执行'vagrant box add --name centos65-base'

• 执行'vagrant init centos65-base'

• 编辑VagrantFile，如下所示：

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure(2) do |config|

  config.vm.define :node1 do |node1_config|
    node1_config.vm.box = "centos65_base"
    node1_config.vm.network "private_network", ip: "10.0.2.5"
  end

  config.vm.define :node2 do |node2_config|
    node2_config.vm.box = "centos65_base"
    node2_config.vm.network "private_network", ip: "10.0.2.6"
  end

  config.vm.define :node3 do |node3_config|
    node3_config.vm.box = "centos65_base"
    node3_config.vm.network "private_network", ip: "10.0.2.7"
  end

  config.vm.define :node4 do |node4_config|
    node4_config.vm.box = "centos65_base"
    node4_config.vm.network "private_network", ip: "10.0.2.8"
  end
end

• 执行'vagrant up'

在第四步结束时，群集的四个节点已配置并启动，这很好 . 我冲进去了 . 我能够从虚拟机成功ping到www.google.com和我的主机 . 但是，从群集中的一个节点ping到另一个节点会出现 "destination host unreachable" 错误 . 我跑了'ifconfig'看到正在使用的网络适配器 . eth0用于DHCP，eth1用于静态ip .

知道如何解决这个问题吗？我需要群集中的VM能够相互通信 .
