It happens on some of the Laptops/Desktops which run on SATA disks/low hardware specs. It may be due to overhead of VirtualBox and/or issue inside the Virtual Machine. Let me take a look into this issue.

Can you post your Host's hardware configuration?

auto eth2
iface eth2 inet dhcp
gateway <IP address of my host machine>

This should not have gateway as it is obtained via. DHCP. This port is connected to NAT network of VirtualBox. It does not allow the instance to talk to your host machine, hence gateway as your host machine will result in loss of internet connection.

I need to put a few more lines on how to debug these issues happening in VirtualBox based installs. Thanks for reporting.
