[one-users] Load balancing in hybrid cloud

[Waterbley Tom]

Hi Ruben,

Thanks for you answer.
What you suggest is a nice solution but the problem with that in a hybrid 
cloud is that public (Amazon EC2) are currently not monitored by OpenNebula.
I'm also not sure if other hypervisors like XEN or VMware are monitored 
correct.

Cheers

Tom
