qemu-img create -f qcow2centos_6.5.qcow2 20G
制作linux镜像
/usr/libexec/qemu-kvm-m 1024 -cdrom iso/CentOS-6.5-x86_64-minimal.iso-drive file=centos6.5-30G.qcow2,if=virtio -net nic,model=virtio -net tap,script=no -boot d -nographic -vnc :0
启动已制作的linux镜像
/usr/libexec/qemu-kvm -m 4096 -drive file=CentOS6.5-x86_64-30G.qcow2,if=virtio -net nic,model=virtio-net tap-nographic -vnc :0
二：制作windows镜像
/usr/libexec/qemu-kvm -m 2048 -cdrom iso/cn_windows_7_ultimate_x64_dvd_x15-66043.iso \
-drive file=virtio-win-0.1-74.iso,media=cdrom -drive file=win7.qcow2,if=virtio \
