similar to: pinning dom0 cpu

Hi everyone, This is for Xen 2.0.3. I''m really interested in the functionality of atropos (enforcing CPU partitioning in a non work-conserving fashion). As I had reported earlier, atropos seemed broken in 2.0. It still seems broken now: $ xm list Name Id Mem(MB) CPU State Time(s) Console Domain-0 0 123 0 r---- 49.1 vm1 1 47

Are there any examples of bvt scheduler parameters usage? If I understand it right, bvt provides me with option to scale domain''s CPU usage. Eg. I have 2 (non-zero) domains pinned to the same CPU. Can I assign eg. 30% of CPU time to domain 1 and 70% to domain 2? (I mean in peaks when both domains are not idle and require the CPU time) If yes, how should I build the "xm bvt"

Does anyone in the devel team recall how the ttylinux rootfs was created, by which I mean what changes were needed? Nothing detailed, just "oh, just /etc/fstab" or whatever. I haven''t yet compared myself, though I''ll figure it eventually. For XenCD, I''d like to ship a pristine ttylinux instance on the ISO image, and have the XenCD startup process copy that

Has anyone expirienced problems with the aic79xx controller and xen 2.0.3 (liinux-2.6.10)? I have got FC3 running and compiled xen-2.0.3 from the sources. The compile ssems to work fine but after rebooting the xen0 domain the server stops during boot at the aic79xx message - no harddisks are recognized. I''ve searched through the mailinglist up and down, asked google but

I am seeing a kernel message, "hdc: lost interrupt", when running LTP on the xen0 domain. The first time I saw the ''kernel: hdc: lost interrupt'' in /var/log/messages, I was running LTP on both xen0 and xenU domains. The xenU domain was totally hung at this point. Suspecting a setup error, I re-checked the installation and reran LTP on xen0 alone, without having

This patch for linux-2.6 defconfig more than quadrupled iperf throughput, restoring the gigethernet network performance to wire speed at long last. Applies to xen-2.0-testing.bk xen-2.0.bk and xeno-unstable.bk The throughput on linux-2.4.29 seems fine. I hadn''t tried it since 2.4.27. The relevant sccs comment, from Dec1: ======== linux-2.6.10-xen-sparse/arch/xen/configs/xen0_defconfig

Hey all, This utility (from Qemu) might be useful to anyone who has multiple partitions on a file-backed VBD and wants occasionally to mount them in dom0. http://www.dad-answers.com/qemu/utilities/QEMU-HD-Mounter/lomount/ You can tell it what partition to mount out of the file and it sorts out the offsets, etc. by parsing the partition table. This allows you to get around the loop

Under xen, either stock xen-2.0.1+linux-2.6.9 or Fedora''s latest (2.6.10-1.1109_FC4), drdb (<http://www.drbd.org/>),as soon as I try to write to one of its devices, causes "Badness" in the kernel and, ultimately, a spontaneous reboot. Under non-xen 2.6.10-1.1109_FC4 and 2.6.9-1.678_FC3, drbd works fine. The error: Jan 25 21:01:23 turing kernel: Badness in blk_plug_device

Hello folks I see the EVTCHN driver being initialized as a part of DomainU. XEND (or domain controller) uses the EVTCHN driver to receive notifications for events on the control interface. However there is no XEND (or domain controller) that runs in DomainU. So what is the purpose of initializing EVTCHN driver in DomainU Thanks in advance Nauzad

I''m attempting to migrate from vmware to xen, however I need to be able to run more than one bridge. Think of it this way: xen0 xenU-1 xenU-2 xenU-3 ------------------------------------------------------------------------ Inside_bridge_1: eth0 vm1_eth0 vm2_eth0 virtual_switch_2: vm1_eth1 vm2_eth1 vm3_eth1 Outside_bridge_3: eth1 vm2_eth2 vm3_eth0 Now, I can modify the existing

Name: python-install.patch Description: Use --root instead of --home --home causes python''s distutils to install into /usr/lib/python/, while --root causes it to install into /usr/lib/python$ver/site-packages, which is the more correct location.

Hi list! I''m trying to run 2.4.29-xenU with grsec. Jacob Gorm Hansen said couple of weeks ago, that grsec should work with xen when pax is disabled.. Well, to get the kernel compiling there''s some source hacking that needs to be done.. I''ll describe what I did and what error I got: I downloaded xen-2.0-testing-src.tgz and extracted it. I edited the toplevel Makefile

I am trying to setup mysql on XEN. I need to set it up on NFS so I can migrate the domain when needed. I am getting unexpected results and wanted to get some feedback. Here is my setup: NFS server Dual 2.0 Ghz AMD Opteron 2GB of RAM Broadcom GB NIC Standard Fedora Core 3 (FC3) Mysql w/tpc-c medium databases on the NFS share XenU filesystem on the NFS share Xen machine

Currently xcs is run by xend in xen-unstable by simply making it a child process. If you launch xend from an ssh session, the session won''t exit because the xcs still is connected to it''s controlling terminal. xcs should daemonize itself to prevent this from happening. This patch does that along with making the domain id => port mapping dynamically allocated. Regards, --

Hi everyone, I understand BVT is not the default scheduler anymore, but perhaps this would be of interest to some people. Some changes in the current BVT scheduler compared to the BVT code in Xen 3.0 has affected its correctness. In the original (Xen 3.0) BVT scheduler the weights resulted in correct CPU allocations. However, the current BVT scheduler (CS 10647:8e55c5c11475) does not do it

I''m a newbie. :) I followed the steps written by Jerone Young: http://sourceforge.net/mailarchive/message.php?msg_id=10562241 but i found an error at the 17th step: 17. mkinitrd /boot/initrd-2.6.10-xen0.img 2.6.10-xen0 it said:"No module ata_piix found for kernel 2.6.10-xen0, aborting." so I commented the line of "module /boot/initrd-2.6.10-xen0.img" in the

There is a patch for xen linux 2.6.10 that enables kdb. It works with the xen 2.0.3 and xen-2.0-testing. (I intend to keep it current with 2.0-testing, but I can''t guarantee instant currency every time there are changes to the test branch.) The patch and a brief HOWTO are located at http://www.ncultra.org/xen/kdb/ kdb works with both privileged and unprivileged kernels. Mike --

Hi everyone, I''m doing some networking experiments over high BDP topologies. Right now the configuration is quite simple -- two Xen boxes connected via a dummynet router. The dummynet router is set to limit bandwidth to 500Mbps and simulate an RTT of 80ms. I''m using the following sysctl values: net.ipv4.tcp_rmem = 4096 87380 4194304 net.ipv4.tcp_wmem = 4096
