[one-users] vnc port in onemc

[Ignacio Martin Llorente]

Dear friends,

Please move this discussion to the ecosystem mailing list, so we could keep this list for opennebula core discussions. We have created the ecosystem mailing list to discuss integration issues of ONE with other components in the ecosystem catalog (http://www.opennebula.org/software:ecosystem).

Thanks!

Ignacio
