Missed eth0 interface after Ubuntu and Guest Addition upgrades

I have Windows 10 host + Ubuntu guest. VirtualBox # 5.0.20.
Today I installed some scheduled updates on the Ubuntu and after this have entered to strange unstable state. Tried to recovery it by uninstalling/installing again the Guest Addition CD. Finally, I installed stable Guest Additions # 5.0.16.
As result, some functionality in the guest machine was returned back. But I lost the Network interface at all. Ifconfig doesn’t show eth0, only ifconfig -a does show (but VirtualBox on Windows shows the interface is up).
On several discussions I saw the decision is to edit/delete file
Code: Select all
/etc/udev/rules.d/70-persistent-net.rules
But it is absent on my guest Ubuntu. Please Help!
Thanks.

Reboot the host and guest and then post the guests log file as an attachment.

It appears to be caused by the yanex program Punto Switcher. Could be a virus or was installed/updated by you and is not signed.

Punto switcher is good keyboard utility I am using many years. It is working together with VirtuaBox on same PC 3 monthes.
The problem with eth0 apeared today after some Ubuntu apgrade. Ubuntu guest stopped to work in 3d accelaration mode. I have downloaded test build VBoxGuestAdditions_5.0.21-107164.iso and installed it. The problem that its uninstaller.sh was empty. Then I tried to install again GuestAdditions 5.0.16. Then I have noticed the network has stopped working.
It seems this GuestAdditions 5.0.21 when installing changed some impotant configuration on the Guest...

Remove the guest additions and boot the guest to see if the network comes back, but I can tell you that the post I added above needs to be addressed. These things can cause a lot of issues.

Hi,
I removed this program Punto, and rebooted. No changes. The logs are attached.
Concerning your advice to uninstall the guest additions: it was the 1st thing I did before opening this topic. It doesn't help.

Thank you, now post the following:
Code: Select all
From the hosts terminal/command window type [b]VBoxManage showvminfo <VM Name> --details [/b] and post here. Replace <VM Name> with the actual name of the VM. Use " " if the name has a space in it.
Note if the host is Windows you need to be in the directory that has VBoxManage.exe for the command to work.
From the guest terminal run and post the following:

- Host bridged address = IPAddress: 10.0.0.100
guest is using the hosts range = NAT: DNS#0: 10.0.0.1
log shows NAT link up
So it looks like the link is being provided to the guest ( link up ) but the guest is not accepting it for some reason. If you still have the live CD can you create a new guest and boot to the Live CD function and see if it can get a network connection?
I should note that the guest additions have nothing to do with the network, host or guest, so I believe that to be a red herring.
You can also try the following in the guest to see if it will help:
edit the /etc/udev/rules.d/70-persistent-net.rules or you can delete the rules and Linux will configure it on the next boot

I can create new VM - it will work. Something happened in my concrete VM. Unfortunately, I didn't create its backup. It contains many stuff I installed previously!
/etc/udev/rules.d - I think this is the problem. There was not 70-persistent-net.rules file here! And it is not created at boot! I even tried to add such empty file, it doesn't help. This /etc/udev/rules.d now contains only some 60-vboxadd.rules file.

OK give me some time to check this all out and get back to you.
One thing I would like for you to test while I am doing this though.
- shut the guest down and go to the settings. Change the adapter from Intel to VirtIO and start the guest.

Ubuntu has changed the way they do the network stack and you probably will not have the rule but look at the following and post the information there.
