Hi All, I have found that the gateway ip can get allocated to the uservms in case of shared networks. This is a corner case and might happen accidentally.
This happens because we allow addition guest ip ranges containing the gateway ip, while creating a shared network and internally there is no check to see if the ip getting allocated is a gateway ip. Simple way to fix this would be to fail the network creation if the supplied guest ip range contains the gateway ip. example gateway=172.16.88.1 netmask=255.255.255.0 guestIpRange=172.16.88.1 to 172.16.88.20. we fail the network creation in this case as the gateway ip is a part of the guest ip range. Any concerns or suggestions regarding this fix ? bug id CLOUDSTACK-7536
