Problem:

- Deploy some VMs on ex. node1 with virtual network using 802.1q driver
- Driver creates phys dev for ex. team0.205 and assign it to bridge onebr5
- Throught API call Hard Terminate all VMs that using that network on that node. So VMs are deleted in same time.
- Driver want deactivate network on that node by deleting onebr5 bridge and team0.205 interface
- Driver fails to deactivate and errors logged in VM
