I don't think it is possible to *guarantee* minimum bandwidth support for ingress. Let's say you have a 10Gb/s link and 10 VMs on a hypervisor. If one VM is receiving more than 1Gb/s of traffic, you can drop the excess but the dropped packets are still consuming link bandwidth and the other 9 VMs are left with <1Gb/s each.
