What is the relation between Virtual Machine Manager and KVM/QEMU? The Wikipedia links says
In computing, the Red Hat Virtual Machine Manager, also known as virt-manager, is a desktop virtual machine manager
and links "virtual machine manager" to https://en.wikipedia.org/wiki/Hypervisor. So if Virtual Machine Manager is a hypervisor, then what is KVM/QEMU?
- Why is VirtualBox not separated into two things in parallel to Virtual Machine Manager and KVM/QEMU? In VirtualBox, which part is similar to Virtual Machine Manager, and which part similar to KVM/QEMU? Or is VirtualBox itself more similar to Virtual Machine Manager or to KVM/QEMU?
- Is it correct that libvirt is a server process, and VMM a client process? Is QEMU also a server to VMM? What is the relation and difference between QEMU and libvirt processes? Do all the four components communicate by KVM <->QEMU <-> libvirt <-> VMM?
