2.加载KVM运行模块
[root@localhost ~]# modprobe kvm
[root@localhost ~]# modprobe -ls |grep kvm
kernel/arch/x86/kvm/kvm.ko
kernel/arch/x86/kvm/kvm-intel.ko
kernel/arch/x86/kvm/kvm-amd.ko
3.创建物理桥
virsh iface-bridge eth0 br0
查看网络
[root@localhost ~]# ifconfig
br0 Link encap:Ethernet HWaddr 00:0C:29:C1:62:56
inet addr:192.168.150.136 Bcast:192.168.150.255 Mask:255.255.255.0

4.创建一块虚拟磁盘:
qemu-img create -f qcow2 /kvm/test003.img 5G
5.创建一个虚拟机:
qcow2格式
[root@localhost ~]# virt-install --name test003 --ram 512 \
--vcpus=1 --disk path=/kvm/test003.img,size=5,format=qcow2,bus=virtio \
--accelerate --cdrom /tmp/CentOS-6.6-x86_64-minimal.iso\
--vnc --vncport=5910 --vnclisten=0.0.0.0\
--network bridge=br0,model=virtio --noautoconsole
raw格式:
[root@localhost ~]# virt-install --name test003 --ram 512 \
--vcpus=1 --disk path=/kvm/test003.img,size=5,bus=virtio \
--accelerate --cdrom /tmp/CentOS-6.6-x86_64-minimal.iso\
--vnc --vncport=5910 --vnclisten=0.0.0.0\
--network bridge=br0,model=virtio --noautoconsole
6.VNC连接

CentOS 5.6下KVM的安装/桥接设置/虚拟机创建及运行
Ubuntu下用libvirt安装KVM虚拟机时找不到/bin/qemu-kvm问题解决
