在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

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
