No. A multi-homed host has more than one network interface.
(It can sometimes be weakened to mean a host with more than
one IP address on the same interface.) HTTP virtual hosting
is when a machine serves more than one web site, i.e. it
has multiple names in the DNS (not necessarily multiple IP
addresses) and its web server software serves different
content depending on the server name in the HTTP request
(or for an old-fashioned setup, the incoming IP address of
the request). It is possible to confuse the weakened meaning
of multi-homing with old-fashioned IP-based virtual hosting.
