Chandan Purushothama created CLOUDSTACK-133:
-----------------------------------------------
Summary: Multiple DHCP Servers are being created on the shared
network on using multiple Network Ranges from the same shared network.
Key: CLOUDSTACK-133
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-133
Project: CloudStack
Issue Type: Bug
Components: Management Server
Affects Versions: pre-4.0.0
Reporter: Chandan Purushothama
Fix For: pre-4.0.0
================
Steps to Reproduce:
================
1. Create Two Shared Networks such that the networks' IP ranges are from the
same VLAN. One shared network's scope is "All" while the second shared
network's scope is specific for Domain '/ROOT/B'

2. Login into an Account in /ROOT/B domain and deploy a VM in the shared
network that has "All" scope access. Observe the deployment of the DHCP Server
in the shared network.
3. Deploy another VM in the two shared networks. Since there is a DHCP Server
already present the shared network with "All" scope access, observe the
deployment of the DHCP Server in the shared network that has domain "/ROOT/B"
scope access only.
