关于VLAN的连接问题

大家好，在CS4.0中，我有两个KVM主机，他们的网桥连接如下：
node1:
brctl show
bridge name     bridge id               STP enabled     interfaces
brprivate               8000.6c626d4248bf       yes             eth1
                                                        vnet1
                                                        vnet4

其中brprivate是manage 和storage，cloudVirBr298是guest,cloudVirBr100是public。cloudVirBr100是public网络因为桥接了物理的eth0,而且cloudVirBr100设置了IP，所以两个节点之前的public可以互相访问。
现在是同一节点里的guest网络可以互联，但是node1和node2里的guest不能互联，请问是什么原因，是不是网桥要如何配置，还是物理交换机是不是也要做什么设置呢？
