Setup: VMWARE with DVSwitch
1. Configure Adv Zone with DVSwitch enabled VMWARE cluster
2. Create an account and deploy VM using default offering guest network.
3. Delete this account. With this all the resources of this account gets removed from cloudstack
But from vCenter dv Switch, the distributed port groups configured for this account guest networks will not get removed.
All the configurations created by cloudstack should get cleaned up as part of smooth removal.
