快速搭建KVM及安装linux系统
1.安装KVM内核及libvirtd相关组件1
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

4.创建一块虚拟磁盘：
1
qemu-img create -f qcow2 /kvm/test003.img 5G

qcow2格式
# 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：
# 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
