Hi, I am planning the roll out of a Xen dom0 running CentOS that is going to be running two DomU''s CentOS and Windows 2003 SBS. I am planning on using LVM for the disks as this (so i have read) increases i/o performance compared to image files. I need a solution to back up these machines and I have came up with the following two ideas: Idea 1, Backup the machines as images (lvm

Hi all, I am running Xen 3.2-1 / 2.6.18 on Debian Etch (Dom0). I setup a Dom0 with several DomUs (Linux). Each DomU disk is a LV partition. I have been seeing a few mails about backups and LVM and just wanted to make sure that what I am doing is correct. Each DomU with a database has a cron that dumps the db with mysqldump. Later on, Dom0 will do an LVM Snapshot of all DomUs and then do a

Hi! DomUs can be backed up just fine, and there''s no problem to restore files as long as the DomU boots. Now I wonder how to recover hard (desaster recovery)... Backing up the disk images or partitions (from Dom0) seems to be not an option, because there are changes to them all the time, so incremental backups would always save them, and all saves would be inconsistent. Now the idea

All, I''ve got one Xen server running CentOS 5, with 3 CentOS virtual machines on it. I have what I hope is a simple question: I''d like to backup the virtual machines. I don''t care about anything but the ability to restore a couple of files and be able to be back up and running quickly. At some point I''ll have a spare server ready to migrate running Xen

Hi all, I''m doing my first xen, running with 3 domU perfect. I need to know which way to backup domU to restore these to another server if i''ve problem with this machine. There are 3 LVM with 10G in VolGroup01 for each domU, with each of these partitions: /dev/xvda3            8,7G  1,4G  6,9G  17%

Hi all. I''m using sles11 for my xen servers. I would really like to be able to do hot snapshots of disk AND memory, and then have these snapshots backed up to tape or off site for disaster recovery. I''m thinking this would be done weekly or monthly, not nightly. Two questions: 1) Is this even possible? 2) I could probably have the systems shutdown to make a clean backups, but

Hello I do have problem using Linux with an external HP tape drive. The server platform is also an HP Server; the server is an HP ML350 G4, and the Tape drive is a HP Storage Works Ultrium 448 - 1U Rack-mountable. HP Ultrium documentation says two drivers should be automatically up, sym53c8xx for LSI SCSI interface "st" for tape and /proc/scsi/scsi should contain information about

Hello, I have a server with a tape. Of course my dom0 see it but I don''t want to manage backups from dom0 and want to do it with a guest. In that case I need to show the tape to the guest. I don''t know how to do it. Is there more than one way? Thanks for your help, nm _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

Hi Friends !!! I have one xen server (debian etch) already in production; there are samba, squid, 2 ldap servers , apache2, postgresql and others, 8 virtual machines at total in a hardware raid5. Now I need a backup system, and i will use bacula with a dell ultrium3 LTO. I would like to know if there are problems with i/o? How can I connect a DomU directly to /dev/st0 of Dom0

Hi. I''m using Xen on RHEL cluster, and I have strange problems. I gave raw volumes from storage to Xen virtual machines. With windows, I have a problem that nodes don''t see the volume as same one.... for example: clusternode1# clusvcadm -d vm:winxp clusternode1# dd if=/dev/mapper/winxp of=/node1winxp clusternode2# dd if=/dev/mapper/winxp of=/node2winxp clusternode3# dd

I'm sure some people will tell me I'm doing it wrong but I always just use rsync for backups, automated in cron. I may be doing it wrong but it always works.

Hi all, I started studying xen to implement some HA cluster hosting multiple guests. I am realizing that xen does not provide any native way to hot-clone or hot-backup a guest. Am I right ? Is there any way to how backup a virtual machine? Or is suspend - copy - resume the only possible tecnique ? Is there any way to clone a virtual machine? Do vm snapshots exists? Thank you for every answer!

Hi, I''m just wondering if there are any speed or stability differences between running a system directly of a LVM partition versus a xvd partition? Basicly: disk = [ ''phy:/dev/LVM/root,xvda,w'', ] vs disk= [ ''phy:LVM/root,hda1,w'',] Any tips? I tried searching the archives but I didn''t find anything. Kind regards, Tarjei

Hello guys Does anyone use lvm2 backends for domU storages ? I do and I wanted to use lvm''s snapshot feature to make backups of domUs in background but I got the following problem. When I create a snapshot LV and copy data from it to backup storage it works perfect. Then I do umount and then lvremove. lvremove asks me if I really want to remove the volume and then just hangs forever.

Hi all, This is my first post to the list, I hope someone out there can help! I am running xen 3.0.3, with CentOS 5.2 based Dom0 (kernel-xen-2.6.18-92.1.22.el5) Recently I have noticed some complete system lockups on a few different servers. Neither Dom0 or any of the guests respond to pings, connecting a keyboard and monitor to the system only shows a blank screen. Nothing is written to logs

I''ve been using lvm under centos to create the backing store for domUs and although the performance seems acceptable it has some shortcomings. The biggest of which is the LVM bug which prevents me from removing an lv (it says it is still mounted and it definitely isnt). I thought this was just a centos bug but it appears to be evident in debian and ubuntu too and I really can''t

Hi Everyone, I am going to get a storage server which will be connected to my Xen hosts via iSCSI/Ethernet. I wish to use LVM for the DomU disks. The storage server will have a RAID10 array, and 2 Xen hosts will connect to this (Each will have a 50% share of the RAID10 array, space wise). What is the best way to go about this? Should I: a) Split the RAID10 array into 2 partition on the

I realize this might be one of those religious topics, but is there any good rule of thumb as to how to setup storage for a Xen domU? Without really knowing any better, I''m basically going to make a disk image of the OS and the create a ''data'' partition on my raid 5 volume for each virtual machine. This is for use at home, so in reality it probably doesn''t
