networking problem

[satimis]

Hi all,

Host ubuntu 16.04
VM ubuntu 16.04
Oracle VirtualBox

I clone VM1 creating VM2
Reinitialize the MAC address of all network cards
Full clone

Start VM2
$ ifconfig

Code: Select all

....
enp0s3    Link encap:Ethernet  HWaddr 08:00:27:3a:4a:33  
          inet addr:192.168.8.2  Bcast:192.168.8.255  Mask:255.255.255.0
          inet6 addr: fe80::8233:e300:c42f:18f5/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:136 errors:0 dropped:0 overruns:0 frame:0
          TX packets:54 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:9654 (9.6 KB)  TX bytes:6988 (6.9 KB)
....

eth0 changed to enp0s3 and unable to connect Internet.

I encountered this problem before but forgot how to fix it. Please help.

TIA

The solution is quite simple. Just edit /etc/network/interfaces
Change all "eth0" to "enp0s3"
Reboot VM

Then it works able to connect Internet.

But above solution doesn't work on "ubuntu-16.04.1-desktop-amd64.iso"

Just install "ubuntu-16.04.1-desktop-amd64" on a VM.

Solution: on terminal run;
Code:

Code: Select all

sudo ifconfig enp0s3 192.168.x.x netmask 255.255.255.0

"192.168.x.x" is the fixed IP

Reboot VM, then Internet can be connected.

Hi,

Thanks for your advice.

sudo ifconfig enp0s3 192.168.x.x netmask 255.255.255.0

Didn't solve the problem. After reboot I have to run this command again.

Finally I found that I haven't installed bridge-utils on VM. After having it installed and on /etc/network/interfaces renaming all eth0 to enp0s3 reboot VM. Problem gone.
