This patch provides a I/O request management framework. This framework can control virtual block device threads at 7 places : * deciding that virtual block devices(threads) is ether going or waiting, * before allocating pending_request variables, * after allocated pending_request variables, * after allocated no pending_request variables (Namely, out of request), * after freed

Enhance adjust_managed_page_count() to adjust totalhigh_pages for highmem pages. And change code which directly adjusts totalram_pages to use adjust_managed_page_count() because it adjusts totalram_pages, totalhigh_pages and zone->managed_pages altogether in a safe way. Remove inc_totalhigh_pages() and dec_totalhigh_pages() from xen/balloon driver bacause adjust_managed_page_count() has

Good evening all, I''ve all but finished installing Xen 2.0.5, XenLinux 2.6.10 and Debian GNU/Linux 3.0r4 into /boot on a colo box currently (and temporarily) running CentOS. I''ve chrooted into the debian install (chroot /boot /bin/bash) and was able to set everything up, install requisite packages, install xen, etc. Now I''m at the last step and I''ve run into

I sent before few days. However, anyone did not comments. So, I resend this patch series. I hope to response for this patch series. This patch series provides the function to display VBD information through xentop. VBD information will be possible to get through sysfs which is locale in /sys/devices/xen-backed/vbd-x-xxxx, by previous patch. In this patch series, libxenstat collects these

VBD information will be possible to get through sysfs which is locale in /sys/devices/xen-backed/vbd-x-xxxx, by previous patch. In this patch series, libxenstat collects these information and xentop display tem. The change from ver.1 is only libxenstat in order to handle sysfs information. I appreciate any

This series of patches provides the function to get counts of I/O requests. This function is useful for managing I/O resources to support workload management. It is important to manage resources such as cpu time, physical pages and disk I/O bandwidth for workload management. In Xen, now, cpu and memory resources can be managed, but I/O resource can not be managed. I think that it is necessary to

Hello, please can someone on the list point me to the right direction how to build xen0 and xenU kernels for linux-2.6.27-xen.hg?

i just ran install.sh from the xen 3.0.2 pre-built distribution. in /boot it put vmlinuz-2.6.16-xen vmlinuz-2.6-xen -> vmlinuz-2.6.16-xen what happened to the xen0 and xenU kernels? also in /boot from xen 3.0.1 is vmlinuz-2.6-xen0 -> vmlinuz-2.6.12.6-xen0 vmlinuz-2.6-xenU -> vmlinuz-2.6.12.6-xenU which is what i expected from xen 3.0.2. don

Hi, I can''t get rid of an annoying domU machines hanging issue with Hyperthreading enabled in my BIOS. Hardware config: IBM x325 series 2 * CPUs Intel Xeon 3.06 Ghz Xen version: 3.0.0 Kernel version: 2.6.12.6 Linux distrib: Debian Sarge 3.1 r1 I run 1 domU machine on my dom0, here is my Xen config: . xen0: /etc/xen/xend-config.sxp : (dom0-num-cpus 0) .

I am installing Xen on a remote server. I left the other kernels on the grub.conf and made xen the default to boot from. The box didn''t boot into Xen on reboot but I''m not sure why. Here is my Xen config file: # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that #
