Ok... So, if it does not works in my computer could it be the apache felix that is broken?
Anything is possible, but this seems like a pretty basic feature.
Do I need to configure something on apache felix in order to get services events wrking?
No.
Alex Please, Can I try your test 'client' bundle in my platform to see what happens?
I will send you it off list. -> richard

Then I installed other (server) bundle and started it but the serviceChanged handler is never called. Why?
