Intro to Virtual Machines With LXD on Linux

[@TrevorSullivan]

Here's a playlist dedicated to LXD! kzbin.info/aero/PLDbRgZ0OOEpX_uqK_hAq98ltdc4DP-D34

Hey Trevor, just wanted to say that this video series is excellent. Thank you for sharing your knowledge with the world!

[@TrevorSullivan]

Thank you, Aaron!! I've been loving learning about, and using, LXD! Creating virtual infrastructure is so easy and accessible for anyone these days! Cheers

[@toolbelt]

Great video. Thank you.

Quick question. when you don't pass --vm flag, it creates a Container. So curious what's the difference betweenn VM and Container. Also what's the difference between Docker container vs lxd container? thanks

[@TrevorSullivan]

@@prajganesh great question! I'm not familiar with all the differences between LXC and Docker containers. I mainly just used LXD to create VMs. I'm sure there's some articles that go into more depth about the differences.

[@prajganesh]

@@TrevorSullivan Thanks for the quick response. I guess with --vm you get a separate vm to do whatever you want to do. if you try to use lxc in a EC2 instance, it only allows you to create containers.. we have to use bare metal EC2 if you need to use --vm.

[@TrevorSullivan]

@@prajganesh yeah that's exactly right, you'd have to use the metal instance types in EC2. I use LXD to create VMs on physical custom built systems at home.

Very nice video, THX.

[@Heavy_Lvy]

you should make the bottom of the video darker so its easier to see the time stamps

[@TrevorSullivan]

Good idea, thanks!

Hello Trevor... back again... I wanted to ask if you have a resource explaining how to create a container with ssh keys pulled from the host or from a github repo?

[@TrevorSullivan]

Hello there! Are you trying to set up an SSH service inside of a container? Is the intent to SSH into the container for debugging? Just curious on more about your use case, thanks!

[@bitferret-rx5rn]

Hello @@TrevorSullivan... I am trying to provision the container with authorised ssh keys so I can login without password

[@TrevorSullivan]

@@bitferret-rx5rn oh I think I see what you mean. You want to import the SSH authorized_keys from the host, when you create a new container? I would think this is possible using a bind mount. Do you know how those work? It basically just links a file or directory inside the container back to the host's file system.

[@bitferret-rx5rn]

@@TrevorSullivan yes.. I realised cloud-init can do that. I am still reading and practicing to find a good path

[@whipncream]

do you think you can elaborate a little on the server side? are you using a server thats in your house or are you paying for access to a server just trying to learn and i cant do that without knowing the step before this and i cant find any documentation on it or sure what to even google if you could help that would be amazing im not expecting a full blown tutorial just a push in the right direction thanks :)

[@TrevorSullivan]

Great question! I have an older desktop workstation at home that I've installed Ubuntu Server on. That's what I used to run LXD VMs on!

[@Tmacs-yp6vv]

Hi Trevor, im unable to apt update or upgrade my ubuntu-vm , do you know how can i troubleshoot this? Thanks, great videos

[@TrevorSullivan]

@@Tmacs-yp6vv thanks for your kind comment. 😊 What error are you getting from apt CLI? Are you positive the VM has internet access?

[@Tmacs-yp6vv]

This has to do with docker engine messing with iptables firewall, i added 2 lines sudo iptables -A FORWARD -i lxdbr0 -j sudo iptables -A FORWARD -o lxdbr0 -j ACCEPT for the bridge adaptor and i was able to get the vm update and upgrades running.

[@jg1000c]

how do you get kvm to work on intel i5 windows box with a linux hyper-v vm?

[@TrevorSullivan]

I'm not sure about KVM, sorry. LXD is pretty awesome though. Any reason you can't use it?

[@jg1000c]

@@TrevorSullivan I'm trying to use it but was getting a kvm error when trying to create a virtual machine with lxc command. I found a guy that did get lxd to work on Windows so I'm going to give it a try. Hopefully it just didnt like hyper-v. I installed Ubuntu from Microsoft Store. kzbin.info/www/bejne/rp69lKanbbKkoZY

@@TrevorSullivan I'm using LXD. I was able to create a container but not VM, Creating the instance Error: Failed instance creation: Failed creating instance record: Instance type "virtual-machine" is not supported on this server: vhost_vsock kernel module not loaded

[@eduardmart1237]

How is it different from docker?

[@TrevorSullivan]

Docker does not create virtual machines. It creates containers that isolate processes.

Hello I do not understand this video You didn't show step by step for windows users You started form your own vm Please make it understandable for windows users
