Hi, I am trying to understand and change the network buffering that is being used by Remus, the HA solution present in Xen. From what i understood from reading the code, Remus calls the postsuspend method of the BufferedNIC after it suspends the domain that sends TC_PLUG_CHECKPOINT message and start the buffering and then calls the commit method of BufferedNIC after it gets the acknowledgement

Hello, I''m using Xen (installed from source - "hg clone http://xenbits.xen.org/xen-4.0-testing.hg") on Debian Lenny. Dom0 kernel is 2.6.32-bpo.5-xen-686. Until now I have successfully ran the Lucid Ubuntu as domU guest, defining disks as (and also as file:): disk = [''tap2:aio:/home/xen/domains/lucid/disk.img,xvda1,w'',

This patch series adds support for network buffering in the Remus codebase in libxl. Changes in V3: [1/5] Fix redundant checks in configure scripts (based on Ian Campbell''s suggestions) [2/5] Introduce locking in the script, during IFB setup. Add xenstore paths used by netbuf scripts to xenstore-paths.markdown [3/5] Hotplug scripts setup/teardown invocations are now

Hello, we are using debian, xen 3.x and a iscsi-storage with ext4 as filesystem. Heartbeat is used for xen-ha. Now we like to change to xen 4 and remus. The iscsi SAN is available on active-Dom0 and backup-Dom0. I don´t have to use the disk buffering, as I understand remus right, because the file system on both machines is the same. With ext4 we don´t had problems at the xen3-Cluster on

hi xen cracks :-) i managed sucessfully to install xen4 on a debian 6.0 squeeze amd64 box, running 3 hosts windows 2008r2 server and 1 host squeeze. i use a hp server dl 160g6 dual processor with 48gb ram and 2 tb disks with sw raid 1. i have an indentical hardware box to setup remus. now, the problem is, i cant find remus on my box, like i saw it in several descriptions: /usr/bin/remus!

Dear List, i''m experimenting with remus with the following setup. dom0: - Debian Squeeze - Jeremy''s 2.6.38.48 kernel - xen 4.1.2 recompiled from sid - DRBD for block device backend domU - Debian Squeeze Remus is working fine unless i try to give more than 1 core to the domU. Here''s the error from remus when i''m trying to enable it for an SMP domU:

Hi, I''m doing my master research and I need to adapt remus code. Now... I wanna get the checkpoint size (memory + disk) on each period. Does someone know what function does this? I think some *fd *object''s function in remus code could just get the memory size. Does someone help me? Thanks _______________________________________________ Xen-devel mailing list

Hi, i already tried to ask this and did not obtain any answer. Is remus is supported in Opensuse Linux actually ? Regards _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Dear all, We are struggling to install xen 4.0 with remus on Ubuntu and debian 6.0. Can you suggest some source that can help us or some distro which has inbuilt feature.

hi xen cracks, i know that this formum might be the wrong one for my question but maybe the last and/or only one what can give me my questions answered. i know how to setup and run a xen infrastructure, i have several server in production. the new thing is, that i started to use the debian squeeze, cause of the native suport of remus (kernel support), as everyone say: hardware ******* hp dl

Hello, I am trying to set up a Xen/Remus test configuration on AMD64 hardware (HP DL380 G6) under SuSE 10.1 and am having trouble. I was able to run and configure the Xen 3 that came with SuSE fine, but as far as I can see, I have to use Xen 4 to get Remus. I managed to build Xen 4 from source and it seemed to install, but I am not sure how to get the proper kernel and/or initrd files in place

Hi everyone I've installed package xen-hypervisor-4.0-i386 (and related) on debian squeeze, using the available debian packages. According to the Remus website http://nss.cs.ubc.ca/remus/ and xen websites, remus (binary) should be available since xen 4.0.1. I can't find the binary though. I have installed: ii libc6-xen 2.11.2-7 Embedded GNU

Hi All, I want to test REMUS over XEN, I would like to know the basic steps to be followed .

Hi, we''re playing around with XEN (kernel 2.6.32) and REMUS. For us, sees this combination of very interesting and we would like to use the productive. However, the configuration is a great effort and often leads to problems. Until the first test position ran, it took several tries. As the further development of REMUS is planned? I''ve read that it will soon be over

Hello, I have been playing around with Remus on Xen 4.0.1, attempting to fail-over for an HVM domU. I''ve run into some problems that I think could be related to tapdisk2 and its interaction with how one sets up Remus disk replication in the domU config file. A few things I''ve noticed: -The tap:remus:backupHostIP:port|aio:imagePath notation does not work for me, although this

Dear all, I have sent this problem earlier but maybe its not detail, here I try to write more detail. I hope anybody can help me to point out the problem. First of all I used Ubuntu 12.04 x64 both for domain0 and domainU with modification to run under xen hypervisor and work with remus. I follow and configured the remus with this notes

hi all: have any one experienced with ha remus? on the official website it says that remus has been included in the official Xen repository and will be seen in the next major release. can i compile it for use on the os like centos with kernel 2.6.18 and default xen hypervisor 3.12? _________________________________________________________________

Hi, We''re trying to use remus for some fault tolerance experiment. We followed the instructions and finished installing and configuring Remus on Xen 4.0.1. We succeeded when running a very simple Linux script on domU: we saw the same domain created on the backup machine. But when we tried to run a Java database benchmark, the dom0 OS crashed on the primary machine. Does anyone have any
