Hi Carlos,
Thanks for your answer.
I was wrong using LEASE instead of LEASES. I find it a little bit
confusing. I followed your advices and it is indeed much better.
Unfortunatly, I've noticed something that looks like a bug in lease
management: if I try to create a new vm with a template already used by
another running vm (with lease reservation), the vm is not created (as
expected), but the lease is freed (not expected).
Tell me what you're thinking about this.
Here's the way to reproduce:
-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.
Best regards.
Stephane
