参考

​​https://docs.openstack.org/image-guide/centos-image.html​​

qemu-img create -f qcow2 /var/lib/libvirt/images/test.qcow2 5G

virt-install --virt-type kvm --name test --ram 500 \
  --disk /var/lib/libvirt/images/test.qcow2,format=qcow2 \
  --network bridge=br0 \
  --location http://172.25.254.250/rhel7.3/x86_64/dvd

只要一个根分区

[]
/pub/cloud-init/rhel7



# yum install acpid
# systemctl enable acpid

# yum install cloud-init

# yum install cloud-utils-growpart

# echo "NOZEROCONF=yes" >> /etc/sysconfig/network

清理虚拟机

virt-sparsify  --compress test.qcow2 new.qcow2

放到发布目录

添加镜像要使用自己的发布目录
