Description of problem: I need to specify a /29 subnet for testing, virt-manager won't let me :(. Version-Release number of selected component (if applicable): 1.0.1 How reproducible: Every time Steps to Reproduce: 1. Edit -> Connection Details -> Virtual Networks 2. Try to create a new network with a /29 subnet mask. Actual results: virt-manager will tell you that's not allowed. :( Expected results: virt-manager will tell you that it works! Additional info: Yes, I hit a real use-case for a /29. When you are out doing interop testing, a /29 is quite useful when the network managers don't hand out clean subnets.
