Let's look at the landscape of partitioning, from least
separated to most.

a program running as root
a program running as a shared user
a program that starts as root and then drops capabilities to run
  as a dedicated user
a program running as a dedicated user
a program running as a dedicated user in a chroot jail
a program running in a container [uses the kernel namespaces
  feature to keep separation for filesystem, network access,
  CPUs]
a program running in a paravirtualized machine [OS calls are
  wrapped and passed through]
a program running in an emulated machine [everything is
  emulated]

libvirt can manage containers, paravirtualized machines, and
emulated machines. KVM/QEMU can handle the latter two.
