This is because Alteon can have more than 1 service to a group of servers.

Lets say I have a group of machine X and Y. This group can have virtual
servers on them, a.vg.no and b.vg.no for example. In Alteon I can say that
if a.vg.no works, then b.vg.no works (only 1 healthcheck as HTTP 1.0). But
I can also set it to healthcheck a.vg.no and b.vg.no. Since a.vg.no and
b.vg.no are on the same servers X and Y, I have to use virtual servers.
Alteon uses HTTP 1.1 to do that. So a.vg.no can be "down" while b.vg.no is
"up".

www.vg.no, 193.69.165.21 and the group of machines that serv it only run 1
service, so Alteon does a HTTP/1.0.

flash.vg.no and the group of servers that serv it have virtual hosts (they
also serv download.vg.no, even if IP adress is not the same, the group of
servers are).
