Hi! I`m using xen 3.0.2 on a Debian Sarge 3,1 (XEON machine)! By default my scheduler is "sedf", ok?! I would like to change it to the "credit"! I tried to set the parameter "sched=credit" in my grub config, but when I try to use the command "xm sched-credit -d <domain>" and others, it doesn`t work! But if I try "xm sched-sedf -l" it

Hello all, I have successfully installed xen 3.0.2 on a dual celeron system. Linux in dom0 works fine. Now, I would like to play with the mini-os (my ultimate goal is to implement a small RTOS as guest in Xen, so mini-os looks like an ideal starting point). However, I can''t seem to get it to run as (I think) it should: It boots up, but as far as I understand the source code and the

Hi All , I am using older xen version xen-3.0.2 which supports BVT and SEDF scheduler I want to add credit and boost credit scheduler support in xen-3.0.2 . Please let me know if any (Credit scheduler) patch is available for xen-3.0.2 Thanks, Akhilesh _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, Sorry to insist, but I would really like to be able to use Xen and my zaptel hardware all together in Dom0. I was just wondering if the 3.1 release could contain some changes compared to 3.0.4 related to IRQ handling or scheduling that could workout my problem. Thanks, François. ---- I actually first asked to asterisk mailing lists, and a few persons told me that it was Xen''s

All, similar to some mail threads found in this forum and some other xen-related threads, I had problems with the network performance of my test system: * software base of dom0/domU: RHEL5 (Xen 3.0.3, Redhat 2.6.18-8el5xen SMP kernel) * ibm x306 servers with 3Ghz P4 /MT support; coupled via Gigabit Ethernet switch * standard xen bridging network configuration * test tool: iperf * Xen

Hi, I am using Xen 4.2.3 installed on an Intel Atom with a Debian Dom0 and 3 Debian domU''s installed. I am trying to run some benchmarks using the Arinc653 scheduler. I have edited my grub options to boot with ''maxcpus=1 sched=arinc653'' options. I can boot the dom0 and verify that the scheduler is enabled. However when I xl create, the VM is created but I cannot

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, I have installed Xen 3.3.1 with Ubuntu 8.04 as dom0 and fedora9 (from jailtime.org) as Dom1. I have more instances of the same fedora9 with separate config files running as other guest domains. But these guest domains dont have any program / application running. So, xm list shows that they are in blocked state as no activity is happening. I wrote a shell script that counts upto large numbers

The SD schedulers significantly impact the spill counts and the execution times for many benchmarks, but the machine instruction (MI) scheduler in 3.3 has very limited impact on both spill counts and execution times. Is this because most of you work on MI did not make it into the 3.3 release? We

Hi, I am using Xenmon to measure performance of Credit and SEDF schedulers. But as you know, the metrics displayed by xenmon keep refreshing on the screen. When I tried redirecting the xenmon output, I am seeing the attached file. Is there any better way to record results which I can use to draw graphs? Please guide.. Thank you Warm Regards Ananth

================== STATUS ================== I do the heavy load test of create/destroy. CREDIT scheduler(cshed_schedule) checks BUG_ON(!vcpu_running) at the end of code. It makes error. The reason is that atomic_inc(&v->pausecnt)@vcpu_pause() is called without lock. (spin_lock(&schedule_data[cpu].schedule_lock)) This lock-less "pausecnt" makes vcpu_running state changing

Our test machine has two Intel Xeon E5540 processors running at 2.53 GHz with 24 GB of memory. Each CPU has 8 threads (16 threads in total). All our tests, however, were single threaded. Which result is particularly surprising for you? The low impact of the MI scheduler, the relatively good performance of the source scheduler or the relatively poor performance of the ILP scheduler? Thanks

So, when the MI scheduler is enabled, will SD scheduling be totally disabled or the SD scheduler will be automatically set to do source scheduling? -Ghassan ________________________________ From: Andrew Trick <atrick at apple.com> To: llvmdev at cs.uiuc.edu Cc: Ghassan Shobaki <ghassan_shobaki at yahoo.com> Sent: Thursday, September 26, 2013 9:24 AM Subject: Re: [LLVMdev]

Hey George, I was wondering if you could explain in simple terms how the scheduler would handle per-physical CPU when there are say 16 guests (each guest is using one VCPU), 32 physical CPUs and dom0 is not restricted to any CPUs. Would the scheduler per physical CPU schedule: guest, dom0, guest, dom0, and so on; or would it be more random? (I assume that both guest and dom0 would do a hypercall
