Systemd also gained similar container support— systemd-nspawn could run namespaced processes and systemd ...LXD is a next generation system container manager. The core of LXD is a privileged daemon which exposes a REST API over a local Unix socket as well as over the network (if enabled).. LXD isn't a rewrite of LXC; in fact it is built on top of LXC to provide a new, better user experience.Under the hood, LXD uses LXC through liblxc and its Go binding to create and manage the containers.There are two major drawbacks: you cannot migrate a running lxc container (it will be shut down, moved and restarted - if using a shared storage, it is often a matter of seconds) and backups to Proxmox Backup Server are slower than a VM's backup. This is because a VM can monitor, thanks to KVM dirty bitmaps, its disk operations to know in ...This section will create a container, install the Apache web server, and add the appropriate iptables rules in order to expose post 80.
