安装必要包

 yum install virt-install
 yum install libvirt
 yum install kvm virt-viewer virt-manager 
	yum install libvirt libvirt-python python-virtinst bridge-utils tunctl
	yum -y install qemu-kvm

  reboot

 systemctl start libvirtd 
 systemctl enable libvirtd 

qemu-img create -f qcow2 centos6.5x64.qcow2 20G

 virt-install --connect qemu:///system  -r 4096 --cpu host \
--name centos6.5x64 \
--network bridge=brqe614c5fd-be,model=virtio \
--disk path=/opt/img/centos6.5x64.qcow2,bus=virtio,format=qcow2 \
--disk path=/opt/img/CentOS-6.5-x86_64-bin-DVD1.iso,device=cdrom,perms=ro \
--vnc --vncport=5915 --vnclisten=0.0.0.0 --noautoconsole \
--os-variant=centos6.5\
 --hvm  --noautoconsole \
--boot cdrom,hd,menu=on

VNC连上5915端口，即可开始安装

--os-variant＝centos6.5
