[Xen-users] Xen 3.x : support for weighted device scheduling ?
Hi,
Is there a way to give different network bandwidth caps to virtual
machines? Or to generalize it further , is there support for weighted device
scheduling like there is for cpu scheduling?
Please help me regarding this, the help will be greatly appreciated.
Thanks and Regards,
Saransh.

Hi, that''s not possible as far as i know. The only to give different bandwidth to different VM''s is to use traffic shaping in Dom0. Someone please correct me if i''m wrong.

Thanks Alex & Todd, btw can this value be changed dynamically (without a reboot of the VM).

Todd Deshane schrieb:> > vif = [''ip=15.25.117.44'', ''rate=10MB/s'']Todd, reading this list shows up interesting things ;) Is this rate parameter generally known to work or does it need special requirements in dom0? Additional, shouldn''t this read vif = [''ip=15.25.117.44,rate=10MB/s''] ? cheers, Stephan _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Xen 3.x : support for weighted device scheduling ?
Hi Saransh, please bear in mind that the "rate" limiting only works for outbound traffic. -> http://www.nabble.com/Network-bandwidth-control-in-Xen-td17421556.html i have set up some simple traffic shaping scripts, that do work dynamically, limit inbound/outbound traffic and guarantee some bandwidth for a particular IP. If you''re interested, i ''d be happy to mail them to you.
