[one-users] opennebula: lease creation and usage

[Carlos Martín Sánchez]

Hi Stéphane,

I can see some problems with the templates you are pasting:

- Your VNet template must use the LEASES attribute instead of LEASE, take a
look at the examples in the doc. [1]

- Inside VM/NIC, NETWORK_UID must be combined with the NETWORK attribute.
If you want to provide the VNET ID, then you need to use  the attribute
NETWORK_ID [2].

- In VM/NIC, the MAC must not be set manually if you are requesting a Lease
from a VNet. It is also a restricted attribute, what means that your
template will only work for oneadmin. Instead, request an specific Lease
from your VNet using the IP attribute [3].
