Hey Qiu Yu, I am a beginner to both lxc and openstack swift. Can you please clarify some of my doubts related to openstack swift and lxc?
1. I want to set up a small cloud storage environment in my laptop. I mean i need to host storage services for some clients and i want to virtualize this environment. Is openstack swift enough for the above purpose or should i install nova, glance and swift?
