  • Fedora Silverblue
  • Kubernetes/K8s
  • systemd-nspawn - Facebook uses it

VMs

Xen/KVM (uses HVM)
QEMU (Emulator and Virtualization - Can be a hypervisor using Xen/KVM for virtualization)
libvirt (Manage multiple hypervisors and emulators (Xen, KVM, LXC, OpenVZ, Virtualbox, etc.) in an unified manner)
GNOME Boxes (uses KVM, QEMU, libvert, SPICE), Virt-manager (GUI for libvirt)

Containers

  • LXC (Linux Containers)

  • LXD (Manager/Hypervison for Containers (LXC) and VMs (QEMU), Waydroid

  • Docker, Podman, Kubernetes (was based on Docker, now uses containerd), Openshift

  • Toolbox, buildah, Distrobox

** "Docker images" are actually OCI compatible images
