Can’t thank you enough for this. After reading half a dozen “guides” with spelling mistakes, inconsistencies, and just terrible explanations, destroying my system as many times and nearly a dozen Ubuntu reinstalls… THIS was the guide and explanation I needed all along! Simple, to the point, and with a good background of how, why, and what we are doing. Thank you again.
I can totally agree, so many weird guides that are all completely different but this video explained it extraordinarily well it's almost unbelievable, my bridge works perfectly and thank you a lot for your effort!
Brother I spent 4+ hours troubleshooting with forums and google searches. Decided to try RUclips and your guide immediately solved my problem. Thank you so much.
It's funny how much the "why" helps so much with the "how" in terms of trying to get your head around what's happening. Especially if you take a wrong turn / use a different tool but want to achieve the same outcome or have to troubleshoot things. Thank you.
I feel compelled to take a moment to thank you for this guide. Like most everyone else commenting, I'm truly grateful I found this video. After watching a handful of other videos (most at least twice as long as this) and reading a number of guides, it wasn't until I watched your guide that I was able to successfully setup a bridged connection for my VMs. My VMs are hosted on Debian 11, but this guide still worked perfectly. Only slight issue I had is that I access my Linux box via VNC/SSH tunnel, so when I deleted the ethernet connection, it took me out. Fortunately I was somewhat expecting this and had an extra keyboard and monitor on hand. I was back up and running moments later. I look forward to watching more of your videos and have subscribed. Thanks again!
Thank you so much! After almost two days trying to make the bridge work in Virt-Manager, I discover in this video that it would only work with a wired network and that I will have to stop using Virt-Manager and start using VMWare! Thank you so much
I appreciate the explanation at the beggining. I already knew all of this but in my search I found so many people confuse a nat with a bridge that it's hard to believe anyone unless they define it.
Can't thank you enough. I've gone threw multiple guides and all of them were missing parts. I think it was the fact the the original physical device needed to be removed. This was super straight to the point but chocked full of useful information. Amazing!
How much can I say thank you this video. I was suffering to make my open5GS core connecting to my UERANSIM on my virtual machine. And you save my life. Thank you very very very much
Excellent. Finally someone who can explain bridge networking simply and clearly. This worked perfectly on Pop OS! 22.04. My VMs now have full connectivity internally and externally. Without having to change tricky configuration files in the host. Thank you.
Hello, thanks for the webinar that helped me a lot to create this bridge on TruNAS Scale version (Dragonfish-24.04.2). You are absolutely right when you say that it is not possible to use Wi-Fi. In my example on my notebook, Wi-Fi is in WAN mode and LAN is in Bridge mode in your method. Once again, my sincere thanks.
How interesting and well explained, you saved my life tonight when you said you could not make it work with wireless networks. I was about to destroy everything here... I will go with virtual box this time! Thanks again!!!!
you are my hero, after reading so many terribly written or outdated instructions about bridging my network your video made it work I can finally go to bed
I love your guides. You explained every step in precise detail, which helps. It also helps you diagramed the concepts and showed how to test if something works.
Your channel is amazing you actually saved me so much time and helped me to understand everything in a simple manner. You earned a new sub, thanks and keep it up !
I'm a Linux newb and just threw out Proxmox, which had no trouble networking. Installed Ubuntu, Kvm and virt manager. First, many VMs probably don't need a bridge, however, my first VM, home assistant, does need external access. Same searching for solutions as others, I'll play and replay, newb, and hopefully get there.😅 Thanks, subscribed! I'll update my comment soon with results! I hope! 😂 Update: Hmmm, newb struggling, fast vid and fast speaker, lol. I'll try again, hello, nmtui.😢 I'll keep trying, maybe make a new connection and delete the old one.
Great video. As mentioned in several comments previously, I looked at a lot of other youtube videos and also went through the documentation and examples on a bunch of other websites. I whacked a couple of setups and ended up with no networking. Following your video, I set up a bridge and can no proceed with the tasks, such as configuring test setups of FreeIPA, and start making progress on other fronts. Again, Thank You!
For you it looks like very easy, for me as beginner you can not imagen what this guide means. You just explained what I really needed. Thank you, thank you thank you, and thank you again. Cheers!
Thanks soooo much for this tuto. It changes my work with virt-manager so drastically, finally I can access my home network. i have been looking for a tutorial for soooo long
Great explanation, very well done and understandable. 5 stars for showing all the steps and proving your work with command line. Many thanks for this video.
Thank you! I have just one issue. When I want to choose the network bridge, it doesnt show it. It doesnt show my bridge that I just created? Do you know what I did wrong, because I followed everything EXACTLY as you did. So I go to virt-manager, go to my NIC, and want to select the network source but it's only showing 1. Virtual network NAT 'default' and 2. Macvtap device.
Thanks so much for doing this. I'm deploying a Cockpit Server and have been trying to wrap my head around the networking of the virtual machine manager. This got me a few steps further in finding the right configuration for my setup. ^^
but i don't understand why is ethernet showing up as interface for the new bridge? why doesn't it have an ip address? how are the vms and host connected to same dhcp server ? the bridged set up is vms/ohost all connect to the bridge then the bridge connects to the router then to the internet so why is hosts's physical NIC (ethernet) showing as interface for the new bridge created?
Fantastic video! Small question. If i create a bridge network on my bare metal, and the bare metal also has docker containers running, does that change something there aswell ?
I can connect to the bridge on the host machine but the guest machine will not connect the the bridge. The guest keeps saying that the activation of the network connection failed. Do you know why this is happening? Thanks
Great tutorial, thanks. I have 2 VMs (VM1 & VM2). They need to be able to communicate with each other while VM2 needs to see the LAN as well as there are home automation devices on the LAN. In addition VM2 needs to see the Internet. Following your video do I setup NAT on VM1 (only sends/receives info from VM2) and bridged networking on VM2? Wonder where to even start with that.
This tutorial is flawless, but I have a similar issue. I am running the vms on a server which has a network card with two physical ethernet ports which are working in balance round robin mode. I have therefore created a virtual bond of the physical ports and set this bond as an interface of the bridge. This doesn't seem too right to me and it doesn't show up in the list of interfaces in virt-manager.Has anyone ever come across this issue or have any suggestions?
ethernet or virbr are just not there when I open nmtui, but the PC is connected using a wired connection. This is fresh ubuntu installation and nothing has been changed.
the putting my machine behind the virtual switch feels like a diaster waiting for me to do it. Would it be possible to buy a usb to ethernet dongle and then configure the bridge to use that dongle instead? This way only the vms are routed through this bridge?
@Abstract programmer thanks for info, i am able to create VMs but after 3 VMs 4 VM is not getting Internet and i observed after 3rd vm all vms(4, 5 ,6 ) are getting same ip and not getting internet, but first 3VMs are working fine with internet, what can be the issue ?
Hi, do you know if its possible to transfer the state of a physical port in the host to a virtual machine logical interface? So basically, when the physical eth0 in the host is down to see the logical eth0 in the virtual machine down as well, is that possible using QEMU/KVM?
Thank you for the insightful video. Is it possible to configure the local network to directly use the public-facing IP address of the router to host a public server?
I need help :( .. I have created my bridge connection, yet it is not an available option in the VM manager. What am I missing or where do I begin to debug this? Thanks. :)
Thank you for your tutorial! It really helped me out. I do have a question. If I want to make a bridge (or maybe other type of network device), without sharing Internet to the VM. So, the VM would be "Internet-less", but the host and the VM could talk to each other still? I do believe it is called host-only. If you have used Hyper-V, there it is called Internal Switch. I think right alternative is isolated network, but I am not sure.
will assign my host to the bridge change my static ip address? the only doubt I got was this one, because when you run the "ip a" command line after setting the bridge your host is no longer conected to ethernet but the bridge, right?
I followed your tutorial and it worked out great But after rebooting I don't know how to connect the host (Debian with xfc) to the bridge So my VM doesn't have internet anymore
I'm not sure what I did wrong and where, but the default NAT bridge KVM installed *does* allow the VMs to communicate with other (real) machines on the network. I can ping them by IP address and connect via Samba client. I need some VMs to be able to do this, but I need some isolated (Internet access only). Anyone have an idea what I did wrong?
Hello, could you show how to solve the issue that happens when I connect on windows 10 to Ikev2 VPN that make lose access to my local SAMBA shares? Thanks!
Doesn't work for me, I did everything thing exactly like you showed it in your vid but Ubuntu won't use the bridge network to connect to the internet also the bridge network doesn't get's an IP address, the thing is I'm new to this and can't help my self
Is this guide still relevant? I'm only asking because I'm having a lot of issues with my bridge. I takes forever to connect to the internet. Today it took three hours. Thank you by the way I do appreciate the guide, I learned a lot from it. I'm just wondering if there are additional steps I should be taking or if maybe I need to find a more recent guide. My host is running Debian 12 Bookworm.
I only just started playing with qemu-kvm about two hours ago. So just for clarification, if I'm using a bridged connection on a VM does that mean the Ethernet connection on my host machine is unusable?
Quite the contrary. You have to connect to the internet via your Ethernet port. What the bridge does, is allow both the host and the guest use this connection.
Is it possible to access physical Network interfaces directly by a Virtual Machine? I have a Linux Mint Host with 6 Network Cards. I need to run Opnsense firewall/router and configure 4 of the network devices as a bridge (under opnsense, which I already do in a dedicated physical PC) to which other separate client computers can connect and access the internet through opensense. I need all clients behind the opnsense firewall to be able to communicate with each other and the internet. So right now, I have a Computer running Opnsense. That PC has 6 Network Cards, 1 for WAN (connected to my internet Modem) and 5 configured as a Bridge/switch, to which my other PC's can connect (talk to each other and the Internet). I'd like to migrate that setup to a Virtual Maching running on the Linux Mint PC. I will add that I would also move my TrueNAS PC system to the Linux Mint Host in a VM as well. So I'd end up with the Firewall/router and NAS running as VM's on the Linux Mint Host. Everything in 1 box, rather than 3 separate PC's.
Hi. I cannot test this, but I see nmtui is part of the "network-manager" apt package which is avalilable on debian repos. In case you need an alternative, here are the commands I ran, they work without nmtui, but also need the "network-manager" package from the apt. First, you need 2 names. The current ethernet connection name and the ethernet device name. To get them, run `sudo nmcli connection show`. Look for the connection of type "ethernet" in the output, and remember its name (you will replace "eth0-connection" with this in my commands) and its associated device (you will replace "eth0" with this in my commands) Here are the commands, please adjust them as mentioned above: ``` sudo nmcli connection down eth0-connection sudo nmcli connection delete eth0-connection sudo nmcli connection add type bridge ifname br0 con-name br0 stp no sudo nmcli connection add type ethernet ifname eth0 master br0 sudo nmcli connection up br0 ``` If anything goes wrong and you want to revert, you can use these commands. Adjust with the correct ethernet device name (replace eth0 from ifname and for simplicity, use the same name in connection name): ``` sudo nmcli connection down br0 sudo nmcli connection delete br0 sudo nmcli connection add type ethernet ifname eth0 con-name eth0 sudo nmcli connection up eth0 ``` Instructions provided without warranty and in good faith. Use at your own risk.
Hello Just one question When did you / How was created the 'nm-bridge' in the Virtual Networks connections? I've watched the video a few times and it does not automagically create it, so that at 11:18 when you open the select box in Network source of the Manjaro VM it appears listed as 'Bridge nm-bridge: Host device enps30', so that you can select it and so on... Excellent exposition and explanation, by the way
Hello :-) This new option, the "nm-bridge" option, is exactly what we need "nmtui" for! That's the new bridge I defined, and connected the physical machine to it! Once the bridge was created, you can use it for your VMs. Btw, for virt-manager to "see" this new bridge, you have to turn it off then back on, that's what I did at 10:48
I have the same issue. After I created a bridge using nmtui just as you specified, I reload the virt-manager and go into the NIC for the virtual machine and it doesn't show the new bridge. I even restarted. The only options I have are Virtual network 'default': NAT, Bridge Device and Macvtap Device. but if I do brctl show, it shows up. Any ideas?
Can’t thank you enough for this. After reading half a dozen “guides” with spelling mistakes, inconsistencies, and just terrible explanations, destroying my system as many times and nearly a dozen Ubuntu reinstalls… THIS was the guide and explanation I needed all along!

Out of all of the tutorials I found lately, yours was the only one working. I now have bridged networking configured and working.
THANK YOU!

Thanks a lot! As others have stated, this is the best guide for setting up bridged connections with QEMU/KVM. The explanation is impeccable
Thanks for your kind words!
I love you. After A TON of resources, finally someone who teach everything properly.
Thank you very much! 👍
How much can I say thank you this video. I was suffering to make my open5GS core connecting to my UERANSIM on my virtual machine. And you save my life. Thank you very very very much
Deleting the default ethernet adapter was the missing link in 2 days of trying, thanks. Well done.
Same story here. I didn't realize I needed to do that. In retrospect it totally makes sense, but nothing I read before explicitly stated that.
Thank you for this. Short, sweet, clear and to the point.
Glad it was helpful!
Thank you so much! After a week of frustration I found this video and now I have all my VMs on my LAN.
I'm glad it turned out well.
Thank you!!! You saved me. After reading lots of guides and having no sucess just came across your video, followed your instructions and it worked!!
I am so glad you found this helpful 😊
Such a clear understanding, thank you! After five guides online I still could not find what I wanted, you helped me a lot.
Glad it was helpful! Thank you for your feedback👍

Thank you, making the transition from Windows to Linux and you just helped me get a bit closer to making that permanent.
Much luck with your Linux journey 😊
Great video. As mentioned in several comments previously, I looked at a lot of other youtube videos and also went through the documentation and examples on a bunch of other websites.

thank you so much, i read 15 different convoluted explanations and struggled for hours with this, your video did it for me in 5 minutes lol
Glad it helped ♥
Thank you for doing the video. The information here is super useful to me. Especially defining the virtual router versus switch.
Great explanation, very well done and understandable. 5 stars for showing all the steps and proving your work with command line. Many thanks for this video.

You're very welcome, thanks a lot!
Thank you so much for this video. After reading many guides that involved a lot of stuffing around this simple fix worked in minutes.
Hi, thx for this super guide, after months of reading about bridges in kvm with osx vm`s this guide did everything in 10 minutes....Thanks again!
It really makes my day to read comments like yours. Thank you so much
i tried a lot of written manuals, but THIS HELPED! Thank you!!!! Ubuntu 20.04 TLS
okay one day after, i did a restart and the connection is gone :(
In a nat network accessing the ip of the virbr from the guests would access the host machine if I remember correctly.
Thanks so much for doing this. I'm deploying a Cockpit Server and have been trying to wrap my head around the networking of the virtual machine manager. This got me a few steps further in finding the right configuration for my setup. ^^
I appreciate your comment Ricardo! It's always great to hear that viewers find my videos helpful
Thank you, thank you, thank you, thank you. That saved me so much time and gave me an actual understanding of how to do this.
I am glad you found this helpful Philipp 😊
This helped me a lot I got to know how network bridge works
You are a goldmine dear sir :) . Best of wishes.
Wow, thank you! 👍
you are a true teacher. thank you so much.
Thanks for your kind words!
Excellent! Just what I was looking for. Saved my day totally!
Appreciate tons for the simple and practical explanation! Thanks!
but i don't understand
why is ethernet showing up as interface for the new bridge?
why doesn't it have an ip address?
how are the vms and host connected to same dhcp server ?
the bridged set up is vms/ohost all connect to the bridge then the bridge connects to the router then to the internet so why is hosts's physical NIC (ethernet) showing as interface for the new bridge created?
Fantastic video! Small question. If i create a bridge network on my bare metal, and the bare metal also has docker containers running, does that change something there aswell ?
Thank you, the most helpful video/source for bridge networking I've seen so far.
Great to hear, thanks!
@@absprog But currently my problem is: in Network source I have selected Bridge nm-bridge:empty source. I have internet on my host PC.
@@absprog nvm, it works now
Do you know how to take snapshots in virt-manager?
Made a video just for you :-)
Just released it, here's the link:

I can connect to the bridge on the host machine but the guest machine will not connect the the bridge. The guest keeps saying that the activation of the network connection failed. Do you know why this is happening? Thanks
This was just what I needed!
Thanks so much :-)
This video is very informative! Exactly what I was looking for. Can't thank you enough.

I am glad you found this helpful👍
ethernet or virbr are just not there when I open nmtui, but the PC is connected using a wired connection. This is fresh ubuntu installation and nothing has been changed.
the putting my machine behind the virtual switch feels like a diaster waiting for me to do it. Would it be possible to buy a usb to ethernet dongle and then configure the bridge to use that dongle instead? This way only the vms are routed through this bridge?
when I use default NAT forward to any devices, host and guest can ping each other, even guest can ping my phone via forward to wifi nic.
@Abstract programmer thanks for info, i am able to create VMs but after 3 VMs 4 VM is not getting Internet and i observed after 3rd vm all vms(4, 5 ,6 ) are getting same ip and not getting internet, but first 3VMs are working fine with internet, what can be the issue ?

I could actually ping the vm from the host and vice versa even before I enabled bridged network. what can be the reason for this?
Thank you, It is REALLY hard to find a clear explanation of KVM bridges and NAT for some reason.
I am glad you found this helpful 👍

why you dont use virbr0 bridge instead of nm bridge?
Is this guide still relevant? I'm only asking because I'm having a lot of issues with my bridge. I takes forever to connect to the internet. Today it took three hours. Thank you by the way I do appreciate the guide, I learned a lot from it. I'm just wondering if there are additional steps I should be taking or if maybe I need to find a more recent guide. My host is running Debian 12 Bookworm.
I run qemu/kvm as normal user instead of root, but got a access denied when selecting "bridge device", do you have any workaround on this? Thanks.
I only just started playing with qemu-kvm about two hours ago. So just for clarification, if I'm using a bridged connection on a VM does that mean the Ethernet connection on my host machine is unusable?
Quite the contrary. You have to connect to the internet via your Ethernet port. What the bridge does, is allow both the host and the guest use this connection.

I need to run Opnsense firewall/router and configure 4 of the network devices as a bridge (under opnsense, which I already do in a dedicated physical PC) to which other separate client computers can connect and access the internet through opensense. I need all clients behind the opnsense firewall to be able to communicate with each other and the internet.
So right now, I have a Computer running Opnsense. That PC has 6 Network Cards, 1 for WAN (connected to my internet Modem) and 5 configured as a Bridge/switch, to which my other PC's can connect (talk to each other and the Internet). I'd like to migrate that setup to a Virtual Maching running on the Linux Mint PC. I will add that I would also move my TrueNAS PC system to the Linux Mint Host in a VM as well. So I'd end up with the Firewall/router and NAS running as VM's on the Linux Mint Host. Everything in 1 box, rather than 3 separate PC's.
This is awesome just what I needed! Thanks for the great tutorial! Subscribed!
Unfortunately NMTui is not in the Debian 12 repos. Any alternatives?
Hi.
I cannot test this, but I see nmtui is part of the "network-manager" apt package which is avalilable on debian repos.
In case you need an alternative, here are the commands I ran, they work without nmtui, but also need the "network-manager" package from the apt.
First, you need 2 names. The current ethernet connection name and the ethernet device name.
To get them, run `sudo nmcli connection show`.
Look for the connection of type "ethernet" in the output, and remember its name (you will replace "eth0-connection" with this in my commands) and its associated device (you will replace "eth0" with this in my commands)
Here are the commands, please adjust them as mentioned above:
```
sudo nmcli connection down eth0-connection
sudo nmcli connection delete eth0-connection
sudo nmcli connection add type bridge ifname br0 con-name br0 stp no
sudo nmcli connection add type ethernet ifname eth0 master br0
sudo nmcli connection up br0
```
If anything goes wrong and you want to revert, you can use these commands. Adjust with the correct ethernet device name (replace eth0 from ifname and for simplicity, use the same name in connection name):
```
sudo nmcli connection down br0
sudo nmcli connection delete br0
sudo nmcli connection add type ethernet ifname eth0 con-name eth0
sudo nmcli connection up eth0
```

Hello
Just one question
When did you / How was created the 'nm-bridge' in the Virtual Networks connections?
I've watched the video a few times and it does not automagically create it, so that at 11:18 when you open the select box in Network source of the Manjaro VM it appears listed as 'Bridge nm-bridge: Host device enps30', so that you can select it and so on...
Excellent exposition and explanation, by the way
Hello :-)
This new option, the "nm-bridge" option, is exactly what we need "nmtui" for! That's the new bridge I defined, and connected the physical machine to it! Once the bridge was created, you can use it for your VMs.
Btw, for virt-manager to "see" this new bridge, you have to turn it off then back on, that's what I did at 10:48
I have the same issue. After I created a bridge using nmtui just as you specified, I reload the virt-manager and go into the NIC for the virtual machine and it doesn't show the new bridge. I even restarted. The only options I have are Virtual network 'default': NAT, Bridge Device and Macvtap Device. but if I do brctl show, it shows up. Any ideas?
@@wdadawdda1 I have here the same issue, I am able to see the bridge at ip addr but at the virtual manager not showing up. any recommendations?
@@yousefalhaj-salem5901 Choose 'Bridge device' in Network source then type in 'nm-bridge' in the Device name and it should work.
I followed the instructions but lost internet on the host after deleting Ethernet in the nm configuration.
I can ping and access guest from the host and the same in the opposite direction
Just what I was looking for! Thank you my man!
Glad I could help!
Cool channel you got there btw ;-)
