Re: [Xen-users] Extending flow control into the vm

We have a data source attached to eth1 that over subscribe the data capacity of peth1. Using pcap on all 4 location, we see that flow control is correctly enforced on peth1 but goes no further. Is there a way to extend the flow control all the way into the vm onto eth1?

This would be flow control, as in the hardware support at the ethernet link layer ? I think that would not make sense in a virtual switch - there is no limit to available bandwidth on these links, and in theory no limit on available packet buffer.

Would enforcing flow rate limits via tc rules do the job ?
