Linux: how to "forward" domains from a virtual machine to a working machine?

Question

linux

Good day!
The problem is the following - there is a virtual machine (on the local machine) with its own domains / subdomains (for example: portal.local, forum.local, blog.local, etc.), you need to make the domains of the virtual machine accessible from the host machine, the question is how?
pS: preferably without "heavy artillery" in the form of DNS, you need something simpler and more "portable", because the virtual machine will have to be hosted on a ppS flash drive

Answer 1

in the /etc/hosts file, write ip and domain name.

Answer 2

nginx on the main machine, proxy_pass on the virtual machine
