[one-users] Incomplete information from hosts polling (VMWare ESXi 4.1 an OpenNebula 2.0.1)

[Ruben S. Montero]

Hi,

You have to add also de CPU capacity for the VM (apart from the number of
virtual cpus CPUs). The CPU value is used at the allocation phase. However
you are specifying MEMORY and should be included in the allocated memeory
(USED MEMORY in onehost show) So I guess there should be other problem with
your template.

Cheers

Ruben
