Thank you for your explanation. It is most helpful. To summarise what I
think is correct: One can run multiple LXC containers, each containing
an identical version of the main host operating system but processes are
separate from the others. KVM creates a type of 'container' allowing
different host operating systems to run in that container.

Can one run inside a LXC container a KVM ?

Can one run inside a KVM some LXC containers ?

Or is the simultaneous usage on the same machine of LXC and KVM mutually
exclusive or incompatible ?


It may not be exactly like LXC but you can also have a look a OpenVZ.
I have been using it on many servers for years with no problems. It is quite lightweight and easy to use.
I think you can run OpenVZ inside KVM as well.
