I am a newbie and have some confusions, hope could get help here:
I have a Ubuntu machine, followed the official doc and got the Container running, then I found it has no add-on, so I went further and got OS KVM running.
I have seen people have multiple containers running instead of an OS with everything, my questions are:
1. Is multiple container an official installation method? I seem could not find help doc.
2. Is multiple container more efficient than a OS in KVM?
