Hi Marco,
The error suggests that a VLAN with the same tag already exists on one of the
PIFs you are trying to create a VLAN on. Would that be possible in your setup?
I don't see anything in your code that checks for this. Note that
Pool.create_VLAN_from_PIF tries to create VLANs on all hosts in the pool.
Cheers,
Rob
