I don't think OP means running VM from within containers (although, who knows, I mean I guess you could). LXD provides a management layer that treats containers and VMs (libvirt/KVM/QEMU VMs) mostly the same. So commands like this work on both containers and VMs: lxc start fedora-desktop lxc mv pi-hole other-machine:pi-hole etc
