[one-users] Added VM IP adresses to the list of VMs in sunstone

[Carlos Martín Sánchez]

Hi Jhon,

Thank you for sharing your code! Users of OpenNebula 3.4 should already see
an IP column in the VM tab [1].

This kind of feedback is really appreciated. We are thinking about how to
present more clearly to new users the meaning of CPU and VCPU, and CPU and
MEMORY monitorization.

Anyway, since we bill by resource allocation and not usage (we do not

The attribute VM/TEMPLATE/CPU should exist if the user defined the CPU in
the template. But CPU is an optional value.
You said that you bill by resource allocation; are you taking into account
this optional attribute?

If you bill users depending on the CPU and MEMORY attributes, maybe
opennebula should provide a way to make any attribute mandatory... We could
add a new section to oned.conf, similar to the restricted attributes [2]
(introduced in 3.4). For example,

VM_MANDATORY_ATT = "CPU"
