このとき、

There was error while creating libvirt storage pool: Call to virStoragePoolDefineXML failed: operation failed: Storage source conflict with pool: 'images'

The box 'centos/7' could not be found or
could not be accessed in the remote catalog. If this is a private
box on HashiCorp's Atlas, please verify you're logged in via
`vagrant login`. Also, please double-check the name. The expanded
