> Key: CLOUDSTACK-1647
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1647
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the default.)
> Components: API
> Affects Versions: 4.2.0
> Reporter: Abhinav Roy
> Assignee: Saksham Srivastava
> Fix For: 4.2.0
>
>
> Steps :-
> ======================
> 1. Create a guest network with Netscaler offering . Once the network is created you will find the CIDR as something like 10.0.144.0/20.
> 2. Now implement the network and implement ip reservation by passing guestvmcidr as 10.0.151.0/20.
> Observation :-
> =====================
> The set of ips which come under the cidr 10.0.144.0/20
> Address: 10.0.144.0 00001010.00000000.1001 0000.00000000
> Netmask: 255.255.240.0 = 20 11111111.11111111.1111 0000.00000000
> Wildcard: 0.0.15.255 00000000.00000000.0000 1111.11111111
> =>
> Network: 10.0.144.0/20 00001010.00000000.1001 0000.00000000 (Class A)
> Broadcast: 10.0.159.255 00001010.00000000.1001 1111.11111111
> HostMin: 10.0.144.1 00001010.00000000.1001 0000.00000001
> HostMax: 10.0.159.254 00001010.00000000.1001 1111.11111110
> Hosts/Net: 4094 (Private Internet)
> is same as the set of ips which come under the cidr 10.0.151.0/20
> Address: 10.0.151.0 00001010.00000000.1001 0111.00000000
> Netmask: 255.255.240.0 = 20 11111111.11111111.1111 0000.00000000
> Wildcard: 0.0.15.255 00000000.00000000.0000 1111.11111111
> =>
> Network: 10.0.144.0/20 00001010.00000000.1001 0000.00000000 (Class A)
> Broadcast: 10.0.159.255 00001010.00000000.1001 1111.11111111
> HostMin: 10.0.144.1 00001010.00000000.1001 0000.00000001
> HostMax: 10.0.159.254 00001010.00000000.1001 1111.11111110
> Hosts/Net: 4094 (Private Internet)
> ----------------------------------
> Expected behaviour :-
> =================================
> In cases like these where the start ip and end ip of guest vm cidr and network cidr are same, the reservation procedure should not go through and user should get a message mentioning that.
