any help will be appreciated

VirtualBox network adapter name on guest machine is not fixed all the time, each time you have disable and enable host adapter from VB prefrences, the network device name post-appended number will increase . For example, if you disable and enable network host-only adapter five times, the new network name should be eth4, and if it was eight times , network name will should be eth7 and so on.
if you don't know what is your current network device name, use:
it will print all available network adapters ( devices ), find your new name and reconfigure /etc/network/interfaces file with new name.
for DHCP configuration use code below with changing eth5 with your current device name
auto eth5 iface eth5 inet dhcp
And for static ip you can code below: ( you still need to change eth5 with your device name, and also the static ip, no need to change netmask in most situations):
auto eth5 iface eth5 inet static address 192.168.56.101 netmask 255.255.255.0
I hope this will help somebody else.
