Solved How to duplicate the tap0 interface in a new tap1 network interface that it is not used

In some of the tries that I did,yes,I could ping ubuntu. But in the lastest tries I couldn't. Don't know why,but I'm getting the error "host is down" when I ping the ubuntu vm from freebsd. We can try also with windows 10,maybe its easier. Even windows 10 can't connect to internet. This is what says ifconfig before to run the VM :

Code: 
root@marietto:/home/marietto # ifconfig

    groups: bridge vm-switch viid-4c918@
    nd6 options=9<PERFORMNUD,IFDISABLED>

at this point,I create the tap0 interface with this command :

Code: 
ifconfig tap0 create up

and I add the tap0 to vm-public :

Code: 
ifconfig vm-public addm tap0

the ifconfig at this point,says :

Code:

as u can see,there are two members on the vm-public interface : em0 and tap0. This is what I see when is vm-bhyve that configures the network. BTW,for sure,vm-bhyve changes some other parameter under the hood.

on ubuntu :

Code: 
ip route list


default via 192.168.1.1 dev enp0s5 proto static metric 100
169.254.0.0/16 dev enp0s5 scope link metric 100
192.168.1.0/24 dev enp0s5 proto kernel scope link src 192.168.1.7 metric 100
 
Yes, you're using the 'bridged' solution.
That is, BTW, what most of the home wifi routers use, less hussle there. Wifi card interface is linked together with LAN and as such has the same IP. That is how it becomes part of the same network...
So you really wanna read more on networking, virtual networks, routing etc. Specifically, for this setup, more about bridges .
VM-BHYVE github page contains a good deal about bridging... though not as much as I would like to. Still, you wanna read it for more information.

So! In this case your tap0 would have the same address as your em0 has -- because they're bridged together. Which means, you won't have to explicitly configure the address in Ubuntu... NetworkManager will automatically (which is the default) pick up the address.
Just there is that problem with NetworkManager -- it is very slow and unpredictable in its workings. Now you have network -- and now you don't!! And after some 5 min, for no obvious reason, you have it again!!! Terrible, I really hate that messy application.

So, currently (in your output) tap0 says 'no carrier' -- because Ubuntu guest is not UP. Once it goes up (your VM machine is launched) When it is UP, the address will be the same -- 192.168.1.6.
Routing information is all right, you have default route via 192.168.1.1, same as your host.

Oh, BTW, you can also open "terminal" app in your Ubuntu desktop and check dmesg output regarding networking.
Like dmesg | grep enp0s5.

IP is layer 3, they're on the same network because it's connected at layer 2. That's what a bridge(4) does, it connects two networks at the data link level.
 
I've tried several times to setup the ubuntu network configuration using the DHCP on the IP4,but even in this case,if I use bhyve,it won't connect. Instead,it works if I use vm-bhyve. I did what u read below several times,but it never worked. Anyway,I did it again to show you. I've created a different netplan file this time,using only the dhcp4 and a new network renderer,called networkd,instead of NetworkManager,that u don't like :

Code: 
network:
  version: 2
  renderer: networkd
  ethernets:
    enp0s5:
      dhcp4: true

this time the error is different when I ping the ip address of google :

Code: 
ping 172.217.21.67
ping connect : the net is not reachable.

Code: 
dmesg | grep enp0s5

virtio_net virtio1 enp0s5: renamed from eth0

BTW enp0s5 hasn't any IP address assigned. Clearly in the site below u can see what's the limit of linux / ubuntu :

itsfoss.com

How to Restart Network in Ubuntu [Command Line & GUI]

Here are 6 ways you can restart the network in Ubuntu and other Linux distros. Also learn to refresh wireless network connection in Ubuntu Linux.
itsfoss.com itsfoss.com

so many alternatives means that u need more and more experience if u want to understand why u get an error. You can expect a lot of headache.
 
according with this site : https://danielmiessler.com/study/manually-set-ip-linux/

I tried also to do :

Code: 
ifconfig enp0s5 192.168.1.5 netmask 255.255.255.0 up
route add default gw 192.168.1.1
echo "nameserver 192.168.1.1" > /etc/resolv.conf

and then :

Code: 
ping google.com
error during the name resolution.

no way.

According with the same website,I tried also :

Code: 
ip link set enp0s5 up

and

Code: 
nano /etc/netplan/*.yaml

network:
  ethernets:
      enp0s5:
          addresses: [192.168.1.13/24]
          gateway4: 192.168.1.1
          dhcp4: true
          optional: true
          nameservers:
              addresses: [8.8.8.8,8.8.4.4]
  version: 2

temporary error during the name resolution.
 
Well!! This is exactly why I DON"T use vm-bhyve and other black-box solutions.
That in the end of it you will have to 'make your hands dirty' anyway!!

BTW, with bridge solution DHCP is not the thing you want, I'm afraid.

Makes no sense just blindly copying without understanding, you see.
As you don't have any name resolution set up at host 192.168.1.1 you will get your error. Why not try a more safe solution like '8.8.8.8'??
 
The name resolution could be [homenet.telecomitalia.it] ; so I tried with this :

I didn't understand what are u saying. vm-bhyve is a wrapper created to make the dirty job. At the end,it works for me. Yes,I don't know what's inside the code because I haven't the right competences and experience. But with them,I can fix this problem easy. Anyone with some experience knows where to look,and in general,how to configure a bridge can find the solution. But for me,that I can't manage complicated configurations,at the end I can use the black box solution because it just works and I can go ahead. I don't do it because I'm tenacious and I want to learn. But soon I will give up,since no one is helping me with the will to find a solution. I created a lot of posts all around the net but I've got a very few useful replies. Yes. My eyes are blind for this job. I think that's natural,since I haven't studied anything of what it is needed to understand what to do. I'm a psychologist. My approach here is to try to understand,to use my intuition,a common sense,the right websites that may contains the solution and some trial and errors. You say to use "gateway4: 8.8.8.8" ? If u mean this :

At the end I've been able to get the result I wanted even without having fixed the main problem. I'm partially satisfied. But it works,so,its ok for now. The main problem that it seems affects only my FreeBSD installation is still there (any bhyve vm [based on linux and on windows] is not able...

yes,I've tried. Don't u think that this is interesting :

Are you connected to the management switch? Some management switches like cisco have smartports that need to be configured to allow more than 1 MAC address per port otherwise your L2 bridge will not work.
 
I'm using ubuntu 21.04 as a guest / VM Os. FreeBSD is my main (host) OS. On ubuntu guest I tried to use the DHCP inside the netplan file. If I use bhyve,it doesn't connect to internet. with vm-bhyve it can. Can u suggest to me to issue some particular commands inside Ubuntu ? So,we can be sure of this.
 
To verify if your bhyve configuration is working test it by creating a new FreeBSD guest virtual machine, boot into LiveCD and obtain DHCP address. You don't have to install the entire guest for that test it's only to check if your bridge is working correctly. To do this you can follow the handbook here: https://docs.freebsd.org/doc/13.0-R...eebsd/handbook/virtualization-host-bhyve.html

With the only change is that instead of downloading 10.3 boot image as it's writed on the handbook you can download the 13.0-RELEASE via
fetch https://download.freebsd.org/ftp/releases/amd64/amd64/ISO-IMAGES/13.0/FreeBSD-13.0-RELEASE-amd64-bootonly.iso

Then if the guest VM obtain the DHCP address you can shut down it and try the same with some other linux distro like Ubuntu.

vm-bhyve create the tap interfaces for you and also bring them up. Don't mix it with traditional bhyve script for starting the VM. You need to choose to use either of them not both.
Now try the same thing but stop vm-bhyve from loading and create the manual bridge0 as it's described in the handbook. Also when you are creating the tap0 interface you don't have to bring it up as it's getting up when the virtual machine is loaded when you have net.link.tap.up_on_open=1

Yesterday I've re-installed Freebsd on a different partition and this time I haven't installed vm-bhyve. I've configured the bridging using this guide : https://wiki.freebsd.org/bhyve/UEFI ; but I've got the same error inside the ubuntu vm. So,I can assure you that to do this :

Code: 
ifconfig tap0 create up
ifconfig vm-public addm tap0

brings the same result as to do this :

Code: 
ifconfig tap0 create up
ifconfig bridge0 create up
ifconfig bridge0 addm em0
ifconfig bridge0 addm tap0

the problem is somewhere else. So,according with your suggestion,I could reboot and try to do :

Code: 
ifconfig tap0 create
ifconfig vm-public addm tap0

Honestly I think that it will not work,since on the handbook,they say to do : ifconfig tap0 create up,you can read by yourself here : https://wiki.freebsd.org/bhyve/UEFI ; it seems that u are suggesting a minor change. what do u think ?
 
docs.freebsd.org

Chapter 24. Virtualization

Virtualization software allows multiple operating systems to run simultaneously on the same computer
docs.freebsd.org docs.freebsd.org

Where in the handbook you see vm-public ? It's a "desc" name create from a vm-bhyve script during the create of the bridge.
Anyway your FreeBSD guest VM get the DHCP address and it's able to ping google.it so it's working. Now you can try the same thing with linux distro.
 
I'm telling that mixing the brigde don't fix the problem,because I've already tried to follow carefully the instructions on the handbook on a fresh installation of FreeBSD and I got the same result. Can u suggest to me which command should I issue inside the ubuntu vm ? because I tried several times to use only a DHCP server and I did : dhcp enp0s5 to get the IP number,but nothing happens. It freezes. Maybe I give the wrong commands.
 
I've attached some screens to show you what happens.

Posting pictures instead of text is wasting bandwidth, hides important information behind useless information and is just unprofessional. I told you before, but you keep on posting pictures. Maybe you will listen to an Admin. Please stop it.

I know,but unfortunately I can't post text from within the ubuntu vm,because Im not connected to internet and the copy and paste don't work. I should copy everything by hand from the VM outside the VM ? I don't think so. I don't have time or will. No one has the time to do something like that. You don't seem very understanding. If you go to see my old posts, where I could, I always wrote messages using text. My reasons sound to you acceptable ?

Ok, if the clipboard does not work you've got a point. But - speaking of me - i don't want to click images and search for a line of text in a 1920×1080 image.

Maybe get copy n paste working first?
