I have installed and Ubuntu Server 15.10 as a VM and set up 2 network adapters - the default NAT + a Bridged on to connect to the VM.

lspci among other thing brings

00:03.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
00:08.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)

In /etc/network/interfaces I have added the second adapter like this (this is what I do Debians using eth0/eth1 and it always works fine):

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto enp0s3
iface enp0s3 inet dhcp

# Host-only network
auto enp0s8
iface enp0s8 inet static
        address 192.168.56.105
        netmask 255.255.255.0
        gateway 192.168.56.1

Each time I change this file I reboot the machine (not sure how to apply the configuration otherwise). So now I can SSH into the machine, but it has no internet connection. When I remove the config for enp0s3, internet works again.

Please advise how to make them work together.

The solution from this question worked for me.

So what I had to do is remove the gateway 192.168.56.1 line.
