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
