Multitenancy means that several projects (old name: tenant) can share the same cloud but be isolated from each other. That is, project 1 can’t see the network traffic of network 2. This is an absolute must in a public cloud, and also many private clouds, where it is important that sensitive information is not shared.

So, two projects can have their respective Kubernetes clusters that are isolated from each other.

The advantage of Magnum is ease of K8s cluster setup and management (also Swarm and Mesos clusters).

KVM implements virtual machines, not containers. In contrast to VMs, containers don’t “run”. They are just boxes without wheels or feet. Apps run in containers. Of course, you can create containers in VMs.

In a physical machine, of course. Magnum can also manage baremetal instances.

Each customer gets a domain in a public cloud, not the passwords of physical servers.

On the other hand, I don’t know if OpenStack’s baremetal solution is well adapted to public clouds.
