快速搭建KVM及安装Linux系统
1.安装KVM内核及libvirtd相关组件
yum -y install kvm Python-virtinst libvirt tunctl bridge-utils virt-manager qemu-kvm-tools virt-viewer
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

eth0 Link encap:Ethernet HWaddr 00:0C:29:C1:62:56

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
