Below I give some simple command to run a ubuntu:16.04 lxd container. LXD container is fast, very efficient, very low-footprint virtual machine. I recommend people who didn’t need low-level system control (such as disk, loopback device) give it a try. I think this kind of lightweight virtual machine would benefit people who study machine learning or similar scientific computing.
# check current status of lxd. If you install lxd the first time, it should containing no virtual machines. lxc list # if my-ubuntu virtual machine not exist yet. lxc launch ubuntu:16.04 my-ubuntu # if my-ubuntu virtual machine already exist. lxc start my-ubuntu # check status of my-ubuntu virtual machine lxc list # login to root account lxc exec first -- /bin/bash # or login to ubuntu account lxc exec first -- /bin/su - ubuntu # stop the virtual machine lxc stop my-ubuntu # you can even copy virtual machine lxc copy my-ubuntu my-ubuntu2 # or rename it lxc mv my-ubuntu stanley-ubuntu lxc mv stanley-ubuntu my-ubuntu # delete my-ubuntu virtual machine lxc delete my-ubuntu # check my-ubuntu is deleted lxc list

Note that lxd has some limitaions. Such as you can’t - setup loopback device - mount fuse file system - have bridged network. - load/remove kernel module … (But if you choose to run a priviledged lxd virtual machine, some limitations might not exist anymore. But I haven’t dig into it currently.)
