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

[Olivier Sallou]

I found that issue is related to domain name.
My hosts have a domain name in Ganglia, not in Open Nebula.
So poll_ganglia on myhost fails while  myhost.mydomain succeeds

To fix this I updated Ganglia.rb to search host with a "starts-with" but
this may not be acceptable as a patch, as a starts-with may cause issue
with other host names in other configurations.
Either domain name should be added automatically, or configured
somewhere....

in /usr/lib/one/ruby/Ganglia.rb, I replaced
xpath="/GANGLIA_XML/CLUSTER/HOST[@NAME='#{host}']"
with
xpath="/GANGLIA_XML/CLUSTER/HOST[starts-with(@NAME,'#{host}')]"
