Apache valittaa virtualhosteista

[harzu]

Käynnistän apachen uudelleen niin tulee tällaista:

apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
[Sun Dec 30 00:32:01 2007] [error] VirtualHost *:80 -- mixing * ports and non-* ports with a NameVirtualHost address is not supported, proceeding with undefined results

Mistä virheet johtuu?

En ole muuttanut etc/apache2/sites-available/ default -tiedostoa mitenkään. Pitääkö sinne tehdä muutoksia?
Olen vain lisännyt virtualhost tiedoston hakemistoon jokaisesta sivustosta.
