"""
The BZ shows that the pool allocates an address which is used in another
pool, although there is another unused address in the pool.
Tricking the allocation pointer to point to a used address is achieved by
exhausting the free addresses in the pool and then removing a vnic so that
there is a free and unused address to allocate, but the pointer points to a
used address and therefore it is wrongly allocated because usability is not
checked.
Flow:
- on cluster_0 (pool_0) create vm_0 with 2 vnics
- remove the second vnic
- move vm_0 to cluster_1 (pool_1)
- create vm_1 on cluster_0
- create a vnic on vm_1: this fails because the allocated address is in use
on vm_0, but it should not fail because there is another free address on
pool_0
