NAT + Host-only adapter

• In Virtualbox Tools, click the VM and set the network configurate to enable interface 1 (NAT) and to enable interface 2 (Host-only adapter).
• In interface 2, expand the advanced options. In the interface type, select Intel PRO/1000 MT Desktop and select deny in the module.
• Start the VM.
• In terminal, list all interfaces.

ip link show

the following is the simple example

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether 08:00:27:78:bf:5a brd ff:ff:ff:ff:ff:ff
3: enp0s8: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
    link/ether 08:00:27:04:e3:e2 brd ff:ff:ff:ff:ff:ff
4: docker0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN mode DEFAULT group default
    link/ether 02:42:48:7d:f1:3f brd ff:ff:ff:ff:ff:ff

There are two main interfaces for the VM, enp0s3 and enp0s8.

• Edit the interface configurates.

sudo vim /etc/network/interfaces

And add the following settings.

# the NAT network configurate
# The primary network interface
auto enp0s3
iface enp0s3 inet dhcp

# the Host-only adapter configurate
# another interface
auto enp0s8
iface enp0s8 inet static
address 192.168.56.101
netmask 255.255.255.0
network 192.168.56.0

• Start the interface.

sudo ifup enp0s8
sudo systemctl restart networking.service

• Check the network configurate.

ifconfig
