Description Itamar Reis Peixoto 2008-02-11 16:02:44 EST
Description of problem: according with this changeset http://xenbits.xensource.com/xen-unstable.hg?rev/dadadf9aeee7 I am able to limit the speed of domU networking, but for me is not working domU config kernel = "/boot/Kernel-xenU" ramdisk = "/boot/initrd-ext3-xenU" memory = 2048 name = "emerson" disk = [ 'phy:/dev/VolGroup00/emerson_root,xvda1,w', 'phy:/dev/VolGroup00/emerson_swap,xvda2,w'] root = "/dev/xvda1" extra = "ro selinux=0 3 console=/dev/xvc0 " vif = ['mac=00:16:3e:36:5b:a1, vifname=emerson, rate=128KB/s'] on_poweroff = 'restart' on_reboot = 'restart' on_crash = 'restart' #on_poweroff = 'destroy' vif section of xm list --long (device (vif (uuid aac1b1bb-ac66-d06d-96f1-f3da0cf360a4) (script vif-bridge) (rate 128KB/s) (mac 00:16:3e:36:5b:a1) (vifname emerson) (backend 0) ) ) after this I am still able to push 5-10mb/s on domU Version-Release number of selected component (if applicable): kernel-xen-2.6.21-2954.fc8 (64bits) xen-libs-3.1.2-1.fc8 (64bits) xen-3.1.2-1.fc8 (64bits)
Comment 1 Itamar Reis Peixoto 2008-02-11 16:06:37 EST
why the domU networking is not limited to 128KB/s rate ?
Comment 2 Daniel Berrange 2008-02-12 10:00:05 EST
FYI, our Xen maintenance team is 100% focused on porting Xen kernels to 2.6.24 + paravirt_ops. This short-term intensive effort unfortunately means we do not have resources to deeply investigate kernel bugs such as this ticket, in the legacy F7/F8 kernel-xen. That said, if anyone can identify patches that will solve this bug we certainly look at applying them in an update. Otherwise I'd recommend trying out a combination of 'tc' and 'iptables' to perform traffic shaping per-guest in the host networking stack.

This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Comment 4 Bug Zapper 2009-01-09 00:58:32 EST
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
