</span>LXD is based on the same technologies as LXC, and has no special<br>
kernel component, so it can only use the same kernel interfaces LXC<br>
uses for containerization. So from that perspective, anything you can<br>
do with LXC, you can do with LXD, and vice versa.<br>
<br>
A major benefit of LXD is in the simplicity of setting up containers<br>
that are isolated from the host and eachother, with the ability to<br>
treat them like VMs with your security posture. To achieve that on LXC<br>
is significantly more work.<br>
<br>
Also, networking is IMO significantly easier with LXD for many common<br>
setups. You won't notice much easier networking in LXD 2.0, but the<br>
latest stable release (2.21) is certainly nice with the amount of work<br>
it does for you.<br>
<br>
The goal of LXD is to become as secure and simple as something like<br>
kvm/qemu/vmware/virtualbox, but without any of the overhead of a<br>
hypervisor, kernel on top of kernel, filesystem on top of filesystem,<br>
etc.<br>
