Hi all,
we are wondering how can we limit a user to use IPs we give him and not others. Best is understood from an example: - we give a user a quota (with x CPU, y memory and z disk space) - a user can create one VirtualMachine with all the resources, or more VirtualMachines with smaller resources. - we want to give a user a pool of IPs. He should not use other IPs. If he uses other IP it should not be routable.
Is there a solution for this problem?
Normal solution: * mirror port on your switch which is forwarded to a NIDS and search for unauthoried IPs MACs pairs "Software foo can to everything" solution: * libvirt know nwfilter * vdsm has hooks thus combination of your own nwfilters, custom properties and vdsm hooks. Or raise a RFE so we could assing nwfilters to a VM.
