perfsonar development work

[Frederic LOUI <>]

Hi Nicolas,

I agree Giovanni and Jochen points.
However, the point of providing VMWare image
does not prevent the project to have a livecd (or better a special 
custom box)

It is there to quickly disseminate the project services showing up its 
various services' capabilities.
In addition, all NRENs administrators are not always familiar with 
JAVA/WEB SERVICES etc.

I also agree the best solution is to have a specific package for 
perfsonar that can be installed flawlessly by the native package 
management. (a .deb, .rpm, pkg ...) In our NREN, we just choose to use 
VMWare because of its simplicity.
Basically, we already had the infrastructure and our VMWare server also 
hosts EDUROAM service.

The proposition does not exclude the other way to spread the project.
It just provide an other convenient alternative to deploy PerfSONAR 
service for
NRENs who want to test and get familiar to the PerfSONAR services quickly.

The point is to make PerfSONAR installation easy taking into account the 
skills level of each person.
