VM Networking ( Libvirt / Bridge )

In this video we explore some deep(ish) networking concepts that pertain to how VMs can communicate with one another!

This is such a great explanation. I've been doing this professionally since 1995 and have never seen such a clear walk through. I'm always looking for teaching materials to share with my team. This is best in class!

I have watched up till 10 minutes as of now but I've learned so much things about Libvert networking that are really not available anywhere . Really man thanks!

[nathanservicesllc]

Very grateful for your methodical hands on approach with thorough explanations....

[benjaminkinder]

This video helped me clarify a lot of the concepts I was muddling through as I build my first home lab! Really appreciated your explanations both in concept & practice!

[micleh]

It's a shame that you haven't been able to post more videos on the topics you mention at the beginning. You're an exceptional YouTuber! You present the topics succinctly, give apt examples and back up everything with solid articles.

Apparently, I used this video almost a year ago. I just rediscovered it as I am back to trying to figure out VM networking. This is hands down the best youtube lecture on an IT subject ever! And the accompanying blog - just fantastic. Thanks so much. You are an excellent teacher.

[mikePOZnoy]

I am so glad I found your channel! You have a natural talent explaining these stuff. Please keep going!

[optimistic_dipak]

The hidden gem...! I am a beginner to all these concepts but still he made me sense to all the things he did in video. All credits to his way of explanation. Thanks Josh. Looking forward for more such vidoes on all the Computer Science topics.

This is one of the best explainer videos I’ve seen. Concise, clear, and informative. Thank you.

[benutza]

Extremely awesome video!
At first I thought because of the length it wouldn't really be structured and just another video covering one specific case while not explaining the bigger picture, but the like-ratio convinced me to watch it either way, and I absolutely wasn't disappointed.
Keep it up!

[AndreasLenze]

Great stuff, thank you! Having worked in the corporate "Windows" world for decades, my personal preference has always been Linux. I love your deep-dive into KVM, especially this networking bit, including the accompanying blog. Keep up the good work!

[sakurira]

This is amazing stuff. So straight to the point! The diagrams and manual walkthrough really drew me in. Thank you, man.

Thanks for your time making these videos and your wandering down the 'rabbit hole' when I was getting my feet wet with VMs, somehow stumbled upon your posts, and for me, learned a few things, but more importantly, had a bunch of 'AHA!' way you wrote them all up/filmed filmed them 'brought it all together' for me; the whole relationship between QEMU/virsh/libvirt, bridged networking (and how to REALLY check to see whats going on with your virtual networks), and everything else in between. Wait for my next review, when I curse your name for making me dabble again with some But seriously man, thanks! +1 in the 'Time Not Wasted' column!

[GutsyGibbon]

This is EXACTLY what I was looking for and wonderfully explained. Great! Thanks so much.

[kanutomay]

Being able to explain complicated matters in simple and understandable ways shows how much you understand the subject in hand. Excellent content

[centredinnovationdelubumba]

This video is awesome! I've learned things that I couldn't find or understand from books. Great job!

[michaelanderson]

Thanks for sharing your expertise on this complex subject. Your videos are exceptional and easy to follow for the layman. I am a 60-something hobbyist experimenting with Linux servers and networking in my home lab. Your videos remind me of being in a community college class and I am grateful to be able to learn from you. Your blogs have also been a great help in supplementing your videos and make it easier for me to grasp the concepts behind what I am doing. Bravo, stay safe, and continued success on your channel.

Excellent educational video from someone who really understand what a bridge is and how it related to VM instances. Thank you.

[thompsoncoding]

Very well done video, thank you! Looking forward to more content on your channel. Firewall configuration in relation to bridging is confusing as heck... your video helped me confirm I was actually doing things right, and clued me in that "something else" was up when it didn't work. I finally figured out this was because net.bridge.bridge-nf-call-* kernel parameters for the br_netfilter module were all set to 1, meaning that bridging was processed by my firewall (and getting nowhere). If you have useful rules for bridging though (e.g. you use docker) you *don't* want to blindly turn those off, but rather look for the iptables/netfilter/ebtables solution appropriate to your needs.

Spent a couple hours on this video, best information ever for setting up a virt bridge. I'm a subscriber now, thank you
