Error when trying to start host on Oracle Virtual Box

Question

I have installed Oracle Virtual box and imported edureka host VM. When I try to start host, getting below network error.

Error:

Could not start the machine edureka_host_vm because the following physical network interfaces were not found:
VirtualBox Host-Only Ethernet Adapter #2 (adapter 2)
You can either change the machine's network settings or stop the machine.

Answer 1

You have to enable the virtualization technology in the BIOS of your local system in order to start the VM. Follow these steps:

Reboot your machine.

• Before your machine starts loading your operating system, press F2 (or button which says setup).
• This will open Bios settings on your machine. 
• You may find an option in your BIOS named Intel virtualization or Intel vt-x. 
• Enable it and save the changes.
