If you start tinkering with VirtualBox network settings, watch out for this: you might make new network adapters (eth1, eth2), yet have your /etc/network/interfaces still configured for eth0.

Diagnose:

ethtool -i eth0
Cannot get driver information: no such device

Find your interfaces:

ls /sys/class/net
eth1 eth2 lo

Fix it:

Edit /etc/networking/interfaces and replace eth0 with the appropriate interface name (e.g eth1, eth2, etc.)

:%s/eth0/eth2/g

In most cases simply switching the virtual machine network adapter to bridged mode is enough to make the guest machine accessible from outside     Sometimes it s possible for the guest machine to not automatically receive an IP which matches the host s IP range after switching to bridged mode  even after rebooting the guest machine   This is often caused by a malfunctioning or badly configured DHCP on the host network   For example  if the host IP is 192 168 1 1 the guest machine needs to have an IP in the format 192 168 1   where only the last group of numbers is allowed to be different from the host IP   You can use a terminal  shell  and type ifconfig  ipconfig for Windows guests  to check what IP is assigned to the guest machine and change it if required     If the host and guest IPs do not match simply setting a static IP for the guest machine explicitly should resolve the issue

Using NAT  the default  this is not possible  Bridged Networking should allow it  If bridged does not work for you  this may be the case when your network adminstration does not allow multiple IP addresses on one physical interface   you could try  Host-only networking  instead    For configuration of Host-only here is a quote from the vbox manual which is pretty good   http   www virtualbox org manual ch06 html      For host-only networking  like with internal networking  you may find   the DHCP server useful that is built into VirtualBox  This can be   enabled to then manage the IP addresses in the host-only network since   otherwise you would need to configure all IP addresses statically       In the VirtualBox graphical user interface  you can configure all   these items in the global settings via  File  -   Settings  -     Network   which lists all host-only networks which are presently in   use  Click on the network name and then on the  Edit  button to the   right  and you can modify the adapter and DHCP settings
