Hi Is it true that the GPLPV drivers is incompatible with QCOW images? The Windows DomU works fine with raw standard "file:/" images, and paravirtualized Linux DomU works fine with QCOW and raw images. If i use QCOW images with my Windows DomU''s i get a stop error: 0x00000007b (inaccessible boot device). It looks like the blkback.3.hda process, that normally starts with

I''m running SLES10 SP1 and have been using file:/ for my file-backed domUs. The domUs sit on a shared OCFS2 SAN-backed filesystem and are run on my three or four XEN servers. I''m having issues with the loopback devices not being released when the domUs shutdown or migrate, so I decided to switch over to tap:aio for my file-backed domUs. This isn''t working, either.

I realise that the hard link limit is in the queue to fix, and I read the recent thread as well as the older (october I think) thread. I just wanted to note that BackupPC *does* in fact run into the hard link limit, and its due to the dpkg configuration scripts. BackupPC hard links files with the same content together by scanning new files and linking them together, whether or not they started

Hi list, is there any working solution for deduplication of data for centos? We are trying to find a solution for our backup server which runs a bash script invoking xdelta(3). But having this functionality in fs is much more friendly... We have looked into lessfs, sdfs and ddar. Are these filesystems ready to use (on centos)? ddar is sthg different, I know. Thx Rainer

Hi, There''s been discussion before on this list on the very small number of hard links supported by btrfs.[1][2] In those threads, an often asked question has been if there''s a real world use case the limit breaks. Also it has been pointed out that a fix for this would need a disk format change. As discussed in bug #15762 [3], there are certainly real-world use cases this

Folks I'm looking for a solution for backups because ZFS has failed on me too many times. In my environment, I have a large amount of data (around 2tb) that I periodically back up. I keep the last 5 "snapshots". I use rsync so that when I overwrite the oldest backup, most of the data is already there and the backup completes quickly, because only a small number of files have

Here are patches to do offline deduplication for Btrfs. It works well for the cases it''s expected to, I''m looking for feedback on the ioctl interface and such, I''m well aware there are missing features for the userspace app (like being able to set a different blocksize). If this interface is acceptable I will flesh out the userspace app a little more, but I believe the

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: We have been looking at implementing deduplication on a backup server. >From what I have been able to find the available documentation is pretty thin. I ended up trying to install LessFS on this CentOS 5.7 box but we have now encountered problems with fuse version. Has anyone out there been able to get LessFS running on CentOS 5.7 and can provide some pointers? If not LessFS can you

I''ve just made my first ever attempt at an Nullsoft installer, so if you want to try it download "Xen PV Drivers 0.9.5.exe" from http://www.meadowcourt.org/downloads/ The installer should detect the version of windows you are running and install the drivers. At the moment you''ll need to install the shutdown monitor service manually, but you can do that from the start

Hi, DomU is a Win2008 R2 64 When i install the GPLPV drivers the network latency goes from 15ms to random numbers up to 1200ms and eventually dies. If you run a ping from the DomU to another host the network stays alive but the high latency is still there. Further more if i try and uninstall the network driver i am unable to use the old one (realtek) as it cannot detect the device.

Well, I seem to have developed a strange issue with the GPL PV drivers in Windows. I''m running Xen 3.2 on SLES 10 SP2 and running some Windows XP HVM domUs. Most (12-15) of my Windows machines work just fine. Two of them, though, have started exhibiting a strange behavior with intermittent network connectivity. Basically, the network starts up and connects initially. After some

Hey, everyone, I''m having some issues with a Xen DomU right related to performance. We have an application that cross-compiles a Linux distribution from scratch for embedded systems. We''re attempting to run this application inside a Xen DomU (paravirtualized, modified guest kernel), and the performance is really bad. The culprit seems to be high I/O wait times related to the

Hey, everyone, I''m running Xen 3.2 (SLES10) and trying to get an OpenSolaris PV domU to run correctly. I''ve followed a couple of the instruction sets out on the Xen wiki and other folks blogs, but I''m running into an issue with the domU crashing. The OpenSolaris version is the latest development release - 5.11-0.128. The config looks like this:

When trying to use the GPL PV drivers with Windows 7 x64 (and testsigning turned on), I get a BSOD with a STOP 0x00000101 error. There''s also an error at the top that says "A clock interrupt was not received on a secondary processor within the allocated time interval." Is this STOP error related to the HPET or other timing adjustments for Xen? Any advice on things I should

This may be a better question for the Xen-Devel list, but I''ll start here... Does anyone know if there is any easy way to replace the gPXE ROM with a newer version in Xen? Also, anyone know if there are any plans to have some sort of option in the domU config file to specify a boot rom? Looks like qemu-dm has an "-option-rom" option - is there any way in Xen to make use of

I'm attempting to configure Samba with CUPS as a centralized print server. I've done this in the past - my current production server is running Samba 3.2.14. On my current production server, I have several users set up as either "admin users" or "print admin" users so that they can manage the drivers, etc., on the Samba server. In setting up my new server, I'm
