    CentOS 6.5下安装Open vSwitch

    准备

    # yum install openssl-devel RedHat-rpm-config kernel-devel -y

    #yum install kvm libvirt python-virtinst qemu-kvm virt-viewer

    编译

    # wget

    #tar -zxf openvswitch-1.9.3.tar.gz

    # cd openvswitch-1.9.3

    # cp ../openvswitch-1.9.3.tar.gz ~/rpmbuild/SOURCES/

    # cp rhel/openvswitch-kmod.files ~/rpmbuild/SOURCES/

    # cp rhel/openvswitch.spec ~/rpmbuild/SPECS/

    # rpmbuild  -ba ~/rpmbuild/SPECS/openvswitch.spec

    # cp rhel/openvswitch-kmod-rhel6.spec ~/rpmbuild/SPECS/

    # ls ~/rpmbuild/RPMS/x86_64/ |grep open

    kmod-openvswitch-1.9.3-1.el6.x86_64.rpm

    openvswitch-1.9.3-1.x86_64.rpm

    openvswitch-debuginfo-1.9.3-1.x86_64.rpm

    # rpm -ihv openvswitch-1.9.3-1.x86_64.rpm  kmod-openvswitch-1.9.3-1.el6.x86_64.rpm

    使用openvswitch

    # virsh net-destroy default

    # virsh net-autostart --disable default

    # service openvswitch start

    # ovs-vsctl add-br br0

    # service network restart

    在KVM中使用OVS

    # yum install bridge-utils tunctl

    [[email protected] ~]# virt-install --name=CentOS65 --ram 512 --vcpus=1  -f /root/kvm/centos65.qcow2 --cdrom /root/CentOS-6.5-x86_64-minimal.iso --graphics vnc,listen=0.0.0.0,port=5920,  --network bridge=br0

    WARNING  KVM acceleration not available, using 'qemu'

    开始安装......

    ERROR    Unable to add bridge br0 port vnet0: Operation not supported

    Domain installation does not appear to have been successful.

    If it was, you can restart your domain by running:

    virsh --connect qemu:///system start centos65

    otherwise, please restart your installation.

    如果不在命令行指定bridge为openvswitch类型 ,libvirt会尝试linux默认的bridge,而virt-install又不支持openvswitch。

    详细参考

    # virt-install --connect qemu:///system --name=centos65 --ram 512 --vcpus=1  -f /home/kvm/centos65.qcow2 --cdrom /home/kvm/CentOS-6.5-x86_64-minimal.iso --graphicsvnc,listen=0.0.0.0,port=5920,  --nonetworks

    virsh # edit centos65

    增加

    <interface type='bridge'>

    <source bridge='br0'/>

    <virtualport type='openvswitch' />

    <model type='virtio'/>

    </interface>

    virsh # start centos65

    配置guest os的网卡

    # cat /etc/sysconfig/network-scripts/ifcfg-eth0

    DEVICE=eth0

    ONBOOT=yes

    TYPE=Ethernet

    HWADDR=52:54:00:D8:D7:FB

    BOOTPROTO=dhcp

    #ifup eth0
