similar to: how to change checkpoint interval

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 guys, It''s my first time here and in a mailing lists, I only participated in forums before. Please, If I make a mistake you should advise me. Let''s go!

This patch series adds support for preservation of the VM generation ID buffer address in xenstore across save/restore and migrate, and also code to increment the value in all cases except for migration. The first patch modifies creation of the hvmloader key in xenstore and adds creation of a new read/write hvmloader/generation-id-addr key. The second patch changes hvmloader to use the new key (as

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, I would like to announce the first release of Kemari, an open-source virtual machine synchronization mechanism for fault tolerance. It offers a feasible approach to fault tolerance that does not require the use of specific hardware or modification of applications/OS. Kemari aims to keep VMs transparently running in times of hardware failures. It transfers the state of the primary VM to the

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

Hi, The following patch series fixes hangup after creating checkpoint on Xen. The Linux Xen guest can be saved the state to restore later, and also created snapshot like checkpoint via the hypervisor. But, when the snapshot is created for the PV guest, it will hangup. We added ''PMSG_CANCEL'' message and ''cancel'' handler in dev_pm_ops struct in the pm-linux

hi folks, i have now a squeeze box, 2.6.39.3, xen 4.2 unstable running. for a remus sync, I need the disks (lvm) to besynced which I wanted to do with drbd protocol D. I downloaded the source from git://aramis.nss.cs.ubc.ca/drbd-8.3-remus drbd-8.3-remus page and made: (http://remusha.wikidot.com/configuring-and-installing-remus) git clone git://aramis.nss.cs.ubc.ca/drbd-8.3-remus drbd-8.3-remus

I want to add some parameters when vm is migrated. As I can see , vmm will use xc_domain_save(tools\libxc\Xc_domain_save.c) function ,and the main function of xc_save.c is responsible for inputting parameters. so I just want to know which function will use this executable file.

This patch series adds support for preservation of the VM generation ID buffer address in xenstore across save/restore and migrate, and also code to increment the value in all cases except for migration. Patch 1 modifies the guest ro and rw node creation to an open coding style and cleans up some extraneous node creation. Patch 2 modifies creation of the hvmloader key in xenstore and adds

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

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:

This patch series adds support for preservation of the VM generation ID buffer address in xenstore across save/restore and migrate, and also code to increment the value in all cases except for migration. The vast majority of the code is in second patch. The first patch merely changes the xenstore key name used by hvmloader to store the buffer address.

Hi Richard thanks for the info. I took the strace approach and ran into this looping over and over again. Is it failing to get time? timer_gettime(0x8, {it_interval={0, 0}, it_value={0, 0}}) = 0 timer_settime(0x8, 0, {it_interval={0, 0}, it_value={0, 250000}}, NULL) = 0 timer_gettime(0x8, {it_interval={0, 0}, it_value={0, 204443}}) = 0 select(16, [0 6 9 13 15], [], [], {1, 0}) = 2 (in [6 13],

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

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
