In the default NAT mode, the recent versions of VirtualBox supports port
mapping. With this feature we can map port X on host machine to port Y
on the guest. Any connections such as web requests arriving on host's
port X would actually be served by a web server on guest's port Y. It
should work well with all ports and protocols but requires adding
explicit mapping for each port.

That entry in the routing table means that any packets to IP address in
the range to will be sent using the newly
created vboxnet0 interface. Host machine will have an IP address in that
range and so should guest (with DHCP or static assignment inside the
guest). You should find the IP address of the guest machine with 'ip
addr list' or 'ipconfig' inside the guest and use that IP in the browser

The IP address you set in File > Preferences -> Network > Host-only
Network is for the host. So when you pointed your browser to that
address you are in fact accessing the web server of host (I suspect you
have one setup on the host). This is why you are unable to find plinth.
Login to guest, set the IP address there (DHCP or manual) and use that IP.

Same problem as above. To understand "Host-only" network, imagine that
you installed a new ethernet card in the host and called it 'vboxnet0'.
Then you added another ethernet card in the guest and called it 'eth0'.
Using a cable you have connected the two ethernet cards. Typically after
that one would setup an IP on the host and another different IP on the
guest and the two machines would be able communicate with each other.
Same is the case with host-only networking. You assign an IP inside the
guest and use that IP from the host.

Apart from the above two options, there is also the Bridged mode option
that is simplest. If you host computer is connecting to a router which
gives automatic DHCP IP address then bridging the guest will put guest
in same network as your host. This is as if you have plugged the guest
machine into the hosts' network. Consequence of this is that guest will
directly take its IP address from the router (or you can assign one
statically). Guest will be accessible from your entire network. Host to
guest and guest to host communication is as if two machines in the
network are communicating with each other. No mappings etc. are required.

It would be nice to have all this documented.
