Hi All, I started working on the the https://bugs.launchpad.net/neutron/+bug/1339028 and realized that we have the same issue with other connected resources in Neutron. The problem is that we have API for the modification of any resources without limitations, for example, we can modify Router IP and connected to this subnet VMs never will know about it and lose the default router. The same situation with routes and IP for DHCP/DNS ports. https://bugs.launchpad.net/neutron/+bug/1374398 https://bugs.launchpad.net/neutron/+bug/1267310 So, we need to have common approach for the resolving these issues. Solution might be the following: - To deny any modification of resources that were created and configured automatically during usual operations. - To provide modification permissions only to admin. What is your opinion? /Thanks and Best Regards, Andrey./ -------------- next part -------------- An HTML attachment was scrubbed...
