This patch -Displays[1] current parameters for running domains ala xm list -Allow users to set[2] one or more parameters[3] without having to provide values for parameters they do not wish to change -Adds additional testing of sched-sedf via new xm-test testcases. With this patch applied, test 02_sedf_period_lower_neg.py exposes a bug[4]. I''ll follow up this email with a patch for

sched_sedf.c used o have its own mechanism for producing tracing-alike kind of information (domain block, wakeup, etc.). Nowadays, with an even not so high number of pCPUs/vCPUs, just trying to enable this makes the serial console completely unusable, produces tons of very hard to parse and interpreet logging and can easily livelock Dom0. Moreover, pretty much the same result this is struggling to

Hi list, I''m using xen 3.0.0 and wonder how to obtain the 6 DOMU scheduling parameters from my DOM0 domain. Sort opposite of the sched-sedf xm sub-command Can someone help me ?

Hi, I had a quick question. I''ve few machines available in a cluster. Now, if I want to install Xen on them, do I individually install in all of them (one by one); or can I have on single image available over a network/SAN and can I boot Xen from there? Are there any other smarter ways to do that? Thanks, Amitayu _______________________________________________ Xen-users mailing list

hello, i have a config that is with a large domain of rate, from 2kb to 40Mb and i have some problems with i don''t know how to deal with. so here are some classes 2 with q=1000, one with q 200000 and one with q=6400, all have been calculated by htb, in the code i speficien just rate,ceil, no quantum, no r2q, no bursts ($tc class add $IF_INT parent 1:2 classid 1:21 htb rate

Hello all, I have a question about the quantum parameter of a HTB class: Is there a formula to calculate the quantum parameter of a class, having the rate and ceil as parameters? Sometimes, if I omit putting the quantum parameter for a class, I get a message like "HTB: quantum of class ..... is big/small. Consider r2q change" and shaping doesn''t work very smooth sometimes.

9d1fd58ff602 was bogous in not letting a new domain being created if its scheduling parameters --when running under the sedf scheduler-- were not fully specified, making creation fail like in this example here below: 2012-06-16 07:37:47 Z executing ssh ... root@10.80.248.105 xl create /etc/xen/debian.guest.osstest.cfg libxl: error: libxl.c:3619:sched_sedf_domain_set: setting domain sched sedf:

Dear all, I''m new to traffic shapping although i have gone through marking and HTB queueing but i felt trouble in tc filter . I wonder if any one give me the hints about quantum or r2q. i guess quantum is used when two class has same prio and rate and want to give first priority between them and control the borrowing traffic. It should be set more than MTU too. But my

Hello, I was very thrilled when I found openstack module since I am in the process of doing some "heavy" testing However I was not able to use it due to the "Could not find declared class quantum::db::mysql" error There is no quantum module available as part of the openstack module installation Here is a directory listing: ls /etc/puppet/modules apache apt cinder

Hi, when we add a class we get an error "HTB Quantum too small,or too big" i read in docum.org that we need to set the quantun value which should be >1500 and <60000. but i need to add classes with diff type of rates. eg : Min : 32 kbit and Max : 512 kbit. now in this case how do i set my quantum value which satifies all types of rates. Pls let me know,This is very urgent for

Hello Stef, I am working on a Bandwidth management project as part of my college curriculum.I am running TCNG 10-b but I am not able to classify packets based on MAC address using tcng, so I am running tc commands in /tcng/bin and they are working. But is there a way out to classify packets based on MAC address using TCNG. And, I am successful in throttling down the Bandwidth to 8kbit

Hello! One simple question regaring htb2->htb3 way. I''m using 2.4.25 kernel with tc3 from Devik''s site, RH9. My data flow is about 100Mbit duplex and is subject to grow, so I''m creating root class with 200Mbit rate, with r2q=10, quantum = rate/r2q, and 1500 < quantum < 200000 (sch_htb.c) with such r2q my default shaping window will be from 120Kbit to 16Mbit,

Hi All, I have a Quantum scalar i40 tape library. I need to configure it to TWO tape partition libraries, e.g., library_a and library_b, so that each library has its own tape drive. Then connect this physical tape library to two different CentOS servers so that each server can see its own media changer and tape drive. I once had a successful configuration on one host but NOT on the other. One

Hi, Can anybody explain to me why the upper limit of quantum of a HTB class is 200000? Why the author choose this number? What if we expand this number, for instant, 500000?

Hey all, When I run my scripts to manage my ungodly slow school connection, I get messages about the quantum size being small and suggesting a r2q change. What is this all about, and should I do anything? my link is effectively 45kBps and I have it set to limit to 42kBps.
