使用virt-install:
（1） qemu-img create -f qcow2 ./centos.img 15G
（2） virt-install –name centos7 –ram 2048 –disk path=./images/centos7.qcow2,size=10 –vcpus 2 –os-type linux –os-variant rhel7 –network bridge=virbr0 –graphics none –console pty,target_type=serial –location ./boot/CentOS-7-x86_64-DVD-1511.iso –extra-args ‘console=ttyS0,115200n8 serial’

for windows7:
(1)qemu-img create -f qcow2 ./windows7.img 50G

(2)sudo virt-install –virt-type=kvm –name windows7 –ram 4096 –vcpus=4 –os-variant=win7 –virt-type=kvm –hvm –cdrom=/home/jack/vms/images/windows7.iso –network=bridge=virbr0,model=virtio –graphics vnc –disk path=/home/jack/vms/images/windows7.img,size=50,sparse=yes,bus=virtio,format=qcow2 –video cirrus

使用virsh:
(1) qemu-img create -f qcow2 ./centos.img 15G
(2) touch centos.xml
