> another running vm (with lease reservation), the vm is not created (as
> expected), but the lease is freed (not expected).

> -First, I create a vm from my template, with the following NIC
> NIC = [ NETWORK_ID = 5,
>         MODEL=virtio,
>         IP=X.X.X.1 ]
> When I do a "onevnet show 5", I see that lease associated with this IP is
> used.
> -Then, I create another vm from the same template (for test purpose). As
> expected, the vm is not created, because lease is already in use. At this
> moment, if I do "onevnet show 5", the lease is not used anymore.
>
> -Finally, because lease has been freed, I'm able to create another vm with
> the template.

>> Hi Stéphane,

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