Unable to connect to localhost after installation of OVA development file

Hi,
I am new to ERPNext. I have installed development OVA file on my VM virtual box. When I logon with Frappe userid, VM boots up successfully.
However when I can not open ‘http://localhost:8080’ on my host system (Windows) browser.

It throws below error -

he connection to the website was reset.
Error Code: INET_E_DOWNLOAD_FAILURE

Do i have to update network settings on my VM? or do we have to do “Bench Start” always on VM? If I do Bench start, ‘Localhost’ actually turns up but it does not allow me to login with Administrator and admin.
