             Summary: PVLAN - 
                 Key: CLOUDSTACK-3250
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-3250
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Management Server
    Affects Versions: 4.2.0
         Environment: Build from master
            Reporter: Sangeetha Hariharan
            Priority: Critical
             Fix For: 4.2.0


1. Advance zone  cluster with 2 hosts. 
2. Create  Shared NW1  scope zone  <pVLAN1, sVLAN1>. 
3. Deploy few Vms in this network. 
4. In my case:
host1 - had SSVM,CPVM and 1 user vm
host2 - had 1 router and 2 user Vms.

Put host2 in maintenance mode.

All the vms running in host2 got migrated to host1.

As part of this migration , we see all the rules relating to the router and 
user Vms that got migrated being reprogrammed in host1. 

But the rules that existed for these Vms in host2 continue to be present in the 
host.

Expected Behavior:
The rules relating to the Vms that migrated out of this host needs to be 
cleared from this host.
