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'',

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

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

Hi Sriram, Once again, thanks for your timely reply.... I tested as your suggesstion and i found that i don''t have any file in the location "/var/lib/xen" [root@globushead xen]# pwd /var/lib/xen [root@globushead xen]# ls -ll total 0 Further i tested the command "xm save " and results as follows Terminal 1: xm save -c TestVM1 TestVM1.chkpt

Hi, I''ve been testing Xen 4.0.1 with kernel 2.6.34.5 + http://gentoo-xen-kernel.googlecode.com/files/xen-patches-2.6.34-4.tar.bz2, and one of the things that I noticed immediately is there are two problems with tapdisk and this combination. First, the syntax "disk = [''tap:tapdisk:aio: ..." no longer works. When tested with HVM domU, it boots, but there was no disk

hi all, coming finally to the end, remus, all works except some questions? 1) I protect 1 guest (remus -i 100 server01 10.41.10.42). how can I protect 3 guests? like to execute 3 commands like remus -i 100 server01 10.41.10.42 remus -i 100 server02 10.41.10.42 remus -I 100 server03 10.41.10.42 2) how can I see if remus works? are there any douc''s for command line switches? 3) does

Hello guys, First of all I need remus support for a Debian 6 system (kernel 2.6.32-5 : Xen-4.1.1). Debian-customized kernels don''t actually support remus. There''s a patch here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=608988 that suggests adding the support for upcomming releases of the kernel, yet only in the wishlist. I have downloaded jeremy''s xen.git

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!

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

Hello I successfully upgraded to xen 4.0 on my Gentoo servers and I''m trying to use remus to enhance servers'' HA. first of all: I''ve tried remus with --no-net option just to test and it works fine, if I try to run it without that option it just stops claiming that no sch_queue module can be loaded. That module is present in xen 4.0 source tree, but my gentoo seems not

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:

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

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

Have an interesting one here, originally found on xen 4.1.0 but just upgraded to xen 4.1.1 and it''s still here. Creating a VM with a tap2 device pointed at /dev/mapper/something, when that device doesn''t exist, causes the tapdisk2 process to go into D mode and also manages to take out any process that queries it. For example, I have /dev/mapper/nathanxenuk1 as a valid disk

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

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? _________________________________________________________________
