fedora17 + qemu-kvm-1.0.1-2 + libvirt0.9.11+openvswitch1.4.2

fedora17 用yum安裝的幾個包都是最新的

qemu-kvm-1.0.1-2 

libvirt0.9.11 （該版本正好支持openvswitch，哈哈）

openvswitch1.4.2

#安裝

yum install libvirt qemu virt-manager qemu-kvm libguestfs sysstat

systemctl start libvirtd.service
systemctl enable libvirtd.service

yum install openvswitch

grep OPENVSWITCH /boot/config-`uname -r`

yum install ovsdbmonitor

#ovs-ctl start將會加載openvswitch所需要的內核模塊，並且初始化啓動歷程：比如創建openvswitch的數據庫，啓動openvswitch的守護進程

/usr/share/openvswitch/scripts/ovs-ctl start

ovs-vsctl add-br ovsbr0

ovs-vsctl list-br

ovs-vsctl show

[root@ucs-3 images]# virsh 
Welcome to virsh, the virtualization interactive terminal.

virsh #

We will want to list the virtual machines, and then edit the XML definition for the virtual machine we just created with virt-manager.

virsh # list --all

虛機配置文件：

    <interface type='bridge'>
      <source bridge='ovsbr0'/>
      <virtualport type='openvswitch'/>
      <model type='virtio'/>
    </interface>

ovs-vsctl add-port ovsbr0 eth0

測試虛機網絡連通性：

創建兩臺虛機，網絡配置文件同上，使用virtio驅動，可相互ping通，且兩臺虛機都能通過eth0接口出去，與外部同網段物理機ping通
