Hi, I have done a small code modification so that the bandwidth limit of each domU can be limited. The implementation goes like this In the file linux-2.6-xen-sparse/drivers/xen/netback/netback.c In the function, net_tx_action netif->remaining_credit and netif->credit_usec values are assigned such that in credit_usec seconds the domain can send remaining_credit bytes. Now I want to implement something like providing guarantees to domains. That is whatever be the bandwidth utilization of say DomU2 DomU1 should be able to deliver at minimum rate similar to setting cpu cap and weights. Can someone point me to some algorithm or reference in this direction Thanks in advance Mathew _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
