network adapter at guest [ubuntu] while setup host only network at virtualbox

I’m trying to setup host only network at virtualbox by following

but facing to choice network adapter at guest [ubuntu]

To see a list of the adapters your virtual machine can access, use this:

ls /sys/class/net

This will show you the interface names. For example, with two network adapters set up, my Ubuntu guest looks like this.

eth1 eth2 lo

To see a list of active network with IP address assigned


So you can easily guess what network adapter should use for host only network.

Well in a brand new ubuntu machine the permanent network save is not work in the way described in that article. For this you need to install ifupdown or ifupdown2 package

apt install ifupdown2

After install execute following command

ifup eth1

Then reboot.
