Basic Network - Router IP allocated to VM ( Invalid IPs )


Hello,

 

       I have a issue with my CloudStack setup, looks like the same issue
persist in last version of CloudStack 4.11.1.  ( previous versions, 4.9,
4.5.2 etc.. )

 

       

        Current setup :

*	CloudStack 4.11.1
*	VMware 5.5
*	Basic Network
*	1(one) zone, multiple POD IP ranges (Guest)

 

         I use the Guest IP as Public IPs for my instances, each IP is
automatically assigned to VM by CloudStack, I didn't customized anything.

 

 

       Here is an example :

 

        IP range :

                                                              Gateway
Mask                                             Start IP
End IP

         


POD01

149.xxx.xx.62

255.255.255.240

149.xxx.xx.49

149.xxx.xx.61


 

 

 

 

 

 

 

      Router IP from this class is : 149.xxx.xx.53

 

 

     After I deploy few instances, one of the Instance will have the router
IP   149.xxx.xx.53 !!   in order to skip this I have to turn off this VM and
leave like this, if I destroy this will happen again.      ( invalid
IP/instance, I cannot use )

 

     On this setup I have 5 IPs ranges, this mean 5 Invalid VMs. 

 

     I have multiple CloudStack environments, I experience this issue only
on the setups with Basic Networking.

 

 

    

     Is there a way to fix this issue, problem?  ( block those IP by being
used for VMs, or.  )

 

   

   Thank you !

 

 

Regards, 

Cristian
