Hi All, Does anybody have this problem when try to migrate DomU : Error: /usr/lib/xen/bin/xc_save 22 6 0 0 0 failed I use xen 4.2.2-pre compiled from sources and my machine is Ubuntu 12.04 Linux with kernel 3.2.0-29-generic. Its working perfectly, even remus with drbd support migration was running successfully before. However today after I kill the remus process with command pkill -USR1 remus

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

Dear all, I am quite new in this virtualization area. I am want to do some experiment with live migration using xen. However, I got problem since my server didn''t support VTx. I am using Ubuntu desktop 12.04 64 bit with Xen 4.1 Amd64. But when I reload the machine it wont start, since the XEN website its doesn''t matter using Paravirtualization without VTx support I dont know

Hi all, Today I got problem below and my domU become unresponsive and I should restart the pc to make it running properly again.

Hi All, First time mailing here. I have installed on a CentOS 7.0 KVM (with DPDK and OVS) one Deep Packet Inspection VM. I have one channel and some virtual traffic generator. The traffic is lost between dpdk vhostuser and the DPI VM. The setup is attached. Any suggestions or ideas? Regarding the OVS+DPDK configuration, the following configuration is already made: - SELINUX is disabled - QEMU

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:

Hello, I have the same error, server is auto rebooted during every boot with kernel XEN, HS20 with Debian Wheezy and XEN hang on and AMM managment show same errors described in previous mails. With Debian wheezy wit non-xen kernel boots correcte, it seems that problems is with xen kernel Same Server HS20 with Debian Lenny+ XEN 3.2 or Debian Squeeze+XEN 4.0 working perfect Upgraded to Debian

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 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

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, 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, 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 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 everyone, I''ve managed to configure and start Remus. However, it works only while the protected server is not loaded. As soon as I start a memory-intensive server application, the stream of Remus messages stops, leaving me with an error message. I think the message is not always the same, but here is what I''ve got from the last run: PROF: suspending at

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 All, I have been trying to do bonpow for a while now.Bonpow works for few graphs and for few others it goes out of memory. I did see reply to one of the posting Alph Centrality Crashed in Igraph memory error. The solution in the posting was to use sparse matrix. This is the link of the message. http://lists.gnu.org/archive/html/igraph-help/2008-04/msg00071.html I was able to obtain

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, 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, I want to test REMUS over XEN, I would like to know the basic steps to be followed . I have installed xen4.1 on debian and i didn''t find any command related to remus, is there any steps which i have to carry out? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
