LXD is a system container and virtual machine manager.
It offers a simple CLI and REST API to manage local or remote instances,
uses an image based workflow and support for a variety of advanced features.
Images are available for all Ubuntu releases and architectures as well
as for a wide number of other Linux distributions. Existing
integrations with many deployment and operation tools, makes it work
just like a public cloud, except everything is under your control.
LXD containers are lightweight, secure by default and a great
alternative to virtual machines when running Linux on Linux.
LXD virtual machines are modern and secure, using UEFI and secure-boot
by default and a great choice when a different kernel or operating
system is needed.
With clustering, up to 50 LXD servers can be easily joined and managed
together with the same tools and APIs and without needing any external

criu.enable: Enable experimental live-migration support [default=false]
daemon.debug: Increase logging to debug level [default=false]
daemon.group: Set group of users that can interact with LXD [default=lxd]
daemon.preseed: Pass a YAML configuration to lxd init on initial start
daemon.syslog: Send LXD log events to syslog [default=false]
lvm.external: Use the system's LVM tools [default=false]
lxcfs.pidfd: Start per-container process tracking [default=false]
lxcfs.loadavg: Start tracking per-container load average [default=false]
lxcfs.cfs: Consider CPU shares for CPU usage [default=false]
openvswitch.builtin: Run a snap-specific OVS daemon [default=false]
shiftfs.enable: Enable shiftfs support [default=auto]

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for Linux Mint 18.2 (Sonya), Linux Mint 18.3 (Sylvia), Linux Mint 19 (Tara), Linux Mint 19.1 (Tessa) and the latest release, Linux Mint 20 (Ulyana).
You can find out which version of Linux Mint you’re running by opening System info from the Preferences menu.
On Linux Mint 20, /etc/apt/preferences.d/nosnap.pref needs to be removed before Snap can be installed. This can be accomplished from the command line:
