Sateesh Chodapuneedi commented on CLOUDSTACK-5666:
--------------------------------------------------
Able to reproduce this issue.
Root cause is that while removing a NIC from VM, the code is trying to fetch
cluster associated with this VM.
But as the its in stopped state, hostId remains to be NULL. Hence
NullPointerException.
Fix is to try to fetch cluster using last host's Id.
> Cant remove a nic when a vm is in the Stopped state
