[one-users] VM status to unknown after switching to Ganglia

[Javier Fontan]

Right know we only search hosts in ganglia with the name provided to
ONE (in your case you've only providede the host name) or IP. When we
do not find the hostname as is the we will try to search in the IP
field. In the case you add hosts in ONE using its IP this wil
hopefully work.

Your idea or adding a common domain name for searching is nice and we
are taking it for a future release.

Cheers
