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.
