Configuring LXD for Charmed OSM


#1

Installing LXD

Your system may already come with LXD pre-installed, but we recommend installing the latest version of LXD via snap. This has the advantage of atomic updates as well as built-in support for the ZFS storage backend, which offers greater performance.

# Remove the apt-installed version of LXD
sudo apt-get remove --purge lxd lxd-client lxcfs liblxc1 liblxc-common

# Install the latest LXD via snap
sudo snap install lxd

Next, we want to initialise LXD:

$ lxd init
