[Bug 712392] Re: qemu-img convert blocks other tasks
I still haven't had the chance to test this properly. (server is in production), but the problem manifested itself by accident. So, here's a little bit of information. I started downloading (rsync) a qcow image from the file server and noticed it was bit slow. 14MB/sec max - 790kB/s after a while. This is writing to a simple single sata disk. Then the virtual machines started to become unresponsive and I had to interrupt the download, or the server would have gone down. It's not memory pressure. Memory was at +/- 900MB (of 8GB). Only 2 small virtual machines were running, BUT there was a snapshot present. It's not qemu-img that causes the panics. Any I/O will do it. Then the famous messages start appearing in kern.log: [149164.740056] INFO: task kvm:21354 blocked for more than 120 seconds.

Unfortunately, this shows up in both host and guests. I haven't tried to use qemu-img on a snapshot, but I will. I fear it will not make much difference. Just having snapshots (without accessing them) is enough to bring the system down on moments with heavy I/O.

Re: qcow2 snapshotting: does it influence future IO performance?
On Thursday 31 March 2011 15:15:35 jurgen.depic...@let.be wrote: Hi Alvin. I read on your site that you stopped work on a project because LVM snapshots potentially decreased IO performance, and I also saw that you worked on a perl project to make copies of VMs, so therefore I address my question directly to you. Your work reminded me of something I read some weeks ago on qcow2 on http://people.gnome.org/~markmc/qcow-image-format.html and which raised my brows at the time: Snapshots - real snapshots - are represented in the original image itself. Each snapshot is a read-only record of the image a past instant. The original image remains writable and as modifications are made to it, a copy of the original data is made for any snapshots referring to it. I tried to find more info about this, but didn't yet. So here's my question: does anybody know whether, having made snapshots of a VM during several stages of its life (clean install, important service installed, ...), affects IO performance of any writes made after snapshotting, as one could suspect from my quote above? There is a difference between qcow2 snapshots and lvm snapshots. You probably want qcow2 snapshots in a typical testing scenario where you start from a good working virtual machine, snapshot it, break it, and then return to your snapshotted situation. I didn't do that yet. Last time I tried, the snapshotting itself hung libvirt, but that was a long time ago. Things might be better now. I have no idea about the resulting performance. They are both 'copy-on-write', so they might suffer from the same problems. I don't know if that's true, but it would be interesting to do some research here. The performance drop caused by LVM snapshots is the reason why I abandoned the project. I originally took the idea from our ZFS setup at work. We're using /a lot/ of ZFS snapshots. It's a success story. If I would ever take that away, the users would be at my door with torches and pitchforks. It's the single reason to still have dealings with Oracle support. So, I started using LVM snapshots at regular intervals. The script I wrote was for easier management and auto-mounting of the snapshots. It ended in disaster and halted production on the Ubuntu servers. The reason is that ZFS snapshots and LVM snapshots are too different. The ZFS faq states that you need about 1GB of RAM for every 10.000 filesystems. That includes snapshots, so that gives you an idea of the possibilities (and the different approach to filesystems). Even a single LVM snapshot can bring an Ubuntu server on its knees and can lead to a kernel panic given the right (in a manner of speaking) circumstances. It seemed a good idea at the time, but it will set fire to your daemons, hang your kernel and send your users screaming. I did file a little bug report[1]. Originally, I thought it was qemu-img, but qemu-img is just a good I/O stress test. You can also use rsync or simply cp to hang the kernel. What I currently do in the above testing scenario is copying the (offline) virtual machine, but I might try the qcow2 snapshots one day. Currently this is not possible because my test vm's run on logical volumes on RAID0. It speeds up the virtual machine itself, but the copying process is heavy and slow. Maybe btrfs will be the answer in the near future?

[Bug 712392] Re: qemu-img convert blocks other tasks
You're right about the errors. Apparently I had a full snapshot, but it doesn't make a difference. Meanwhile, I've had the time to test this. It is easy to reproduce: - Create a snapshot (1 is enough) - Cause some I/O, like qemu-img convert (this does /not/ have to be the snapshotted volume) - Watch your virtual machines crash and/or your system burn Doing the same qemu-img without any snapshots present is no problem. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in ubuntu. https://bugs.launchpad.net/bugs/712392 Title: qemu-img convert blocks other tasks -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

What's the recommended way to get the latest versions there? What exactly is your goal?

So how would removing them to see the boot process cause the filesystem mounts to fail?? Yes, it is starting to mount filesystems, but something could go wrong. Some examples: Lucid beta will not succeed if you have more than 4 lvm filesystem defined in /etc/fstab.

Or, you could have defined dhcp in /etc/network/interfaces, which will cause resolv.conf to stay empty. If you mount network shares by hostname, this will halt your boot process. [https://bugs.launchpad.net/bugs/558384] With splash, plymouth will ask what to do. (for example, skip mounting that filesystem, or go into recovery shell,..)

Sometimes, it is needed to go into a recovery shell, mount manually, and continue booting (with some other errors). This is all good if you can manage the console, but for human beings who will be using some of these systems, it's just too much to ask. (I mentioned this and other bugs in a previous post (Earth Computing), but there were only personal reactions.) The good news is, that this is fixed in lucid. The bad news is: karmic will remain broken. I contacted Canonical a while ago, and a support contract will give you the right to 10 support cases per annum. I'm perfectly willing to pay for support, if only to give some people the chance to be payed for the work they do on Ubuntu. The situation with bugs (I quote): - Support customer bugs receive higher priority by Canonical developers. - Bugs reported as support cases do not actually count against your allocation of support tickets for that subscription. - Bugs that require assistance from upstream projects are also managed directly by Canonical, increasing the likelihood, and speed of successful resolution. So, the bugs I mentioned in my previous post would receive higher priority.

[Bug 351307] Re: Libvirt NFS mount on boot.
I can confirm that NFS mounts are not automatically mounted, when libvirtd is started during boot. I don't know if that's the actual bug, because it's new in karmic I think. -- Libvirt NFS mount on boot. https://bugs.launchpad.net/bugs/351307 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 427539] Re: [FFe] Sync libmaven packages from Debian unstable
Mathias, I'm not sure I understand your comment. Isn't it the maintainer's job to maintain Maven? By your logic, if I don't know enough about the trip computer in my car to maintain it, I shouldn't rely on my car? Also, I love Ubuntu and have been using it exclusively since Breezy, but it does have a bit of a reputation for having bugs that go unfixed (often for years) unless a critical mass of people are vocal enough about them. Clearly, maintainers are volunteers and don't have the time to fix every bug, and that's why I would think that comments such as the ones you mentioned are critical for helping you decide which get priority. -- [FFe] Sync libmaven packages from Debian unstable https://bugs.launchpad.net/bugs/427539 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libgoogle-collections-java in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 427539] Re: [FFe] Sync libmaven packages from Debian unstable
I agree with comment #37.
