Hi Ali, First thing (and I think I have said to you a few times now), OpenFlowVMS is a deprecated package. Take a look at mininet.
OpenFlowVMS uses a read-only filesystem so that all the VM can share an image. So, you have two choice. Make VMS run in read-write mode (i.e., remove the -snapshot option) or make your code only read and send, and not write to the filesystem. Hope that helps.
