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.
my take is that as long as you use an external ip allocation mechanism (dhcp/static) - its up to you to limit. once engine will do the allocations (IPAM, or L3), then quota's for IP addresses could be relevant.
