1.CoreOSのダウンロード
mkdir -p /opt/virt/kvm/ ; cd /opt/virt/kvm/
wget http://alpha.release.core-os.net/amd64-usr/current/coreos_production_qemu_image.img.bz2 -O - | bzcat > core01.img
#wget http://beta.release.core-os.net/amd64-usr/current/coreos_production_qemu_image.img.bz2 -O - | bzcat > core01.img
#wget http://stable.release.core-os.net/amd64-usr/current/coreos_production_qemu_image.img.bz2 -O - | bzcat > core01.img

2.XMLの作成
