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 http://openvswitch.org/releases/openvswitch-1.9.3.tar.gz

#tar -zxf openvswitch-1.9.3.tar.gz

# cd openvswitch-1.9.3

virsh net-autostart --disable default

 

service openvswitch start

KVM中使用OVS

yum install bridge-utils tunctl

 

[root@yinye ~]# 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bridgeopenvswitch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
