And the Jaunty patch for jaunty-proposed. ** Attachment added: "jaunty-404294.debdiff" http://launchpadlibrarian.net/35112091/jaunty-404294.debdiff
** Description changed: Binary package hint: kvm Since the latest update to 1:84+dfsg-0ubuntu12, any existing or new kvm host using a qcow2 file encounters disk errors and eventual lockup inside the guest. The errors inside the guest (root is /dev/vda1, other filesystems are lvm on top of /dev/vda2). This can happen at bootup if there is enough IO, or boot just fine and occur when IO picks up. ---- REISERFS: abort (device dm3): Journal write error in flush_commit_list REISERFS: Aborting journal for filesystem on dm-3 request_module: runaway loop modprobe binfmt-0000 Buffer I/O error on device dm-3, logical block 1063056 Buffer I/O error on device dm-3, logical block 1063072 ... ad infinitum ---- Converting the qcow2 to a raw and back to qcow2 does not work, nor does using the newer version of qemu-img (v0.10.0) from the 'qemu' package to convert the raw to qcow2. Problems occur on 9.04 and 8.04 - both are x86_64 and have all the latest updates applied. KVM Host: Linux ronto 2.6.28-13-server #45-Ubuntu SMP Tue Jun 30 22:56:18 UTC 2009 x86_64 GNU/Linux KVM Guests: Linux halfrun 2.6.24-24-server #1 SMP Tue Jun 30 20:24:57 UTC 2009 x86_64 GNU/Linux Linux zack 2.6.28-13-server #45-Ubuntu SMP Tue Jun 30 22:56:18 UTC 2009 x86_64 GNU/Linux LVM setup: - * /kvm is an LV on the Host where the guest qcow2 files are stored - * Each qcow2 file has two partitions, vda1 (root) and vda2 (a PV for LVs inside the Guests of which var/tmp/swap are LVs) + * /kvm is an LV on the Host where the guest qcow2 files are stored + * Each qcow2 file has two partitions, vda1 (root) and vda2 (a PV for LVs inside the Guests of which var/tmp/swap are LVs) + + ============ + SRU Verification + 1) Follow *precisely* the instructions in Comment #6 by Nathan. This reproduces the problem for me every time on the *ubuntu12.3 version of the package. + 2) Upgrade to the proposed version of this package, and retry those instructions. The problem does not occur. + ============ ** Changed in: kvm (Ubuntu Hardy) Importance: Undecided => High ** Changed in: kvm (Ubuntu Karmic) Importance: Undecided => High ** Changed in: kvm (Ubuntu Intrepid) Importance: Undecided => High ** Changed in: kvm (Ubuntu Karmic) Assignee: (unassigned) => Dustin Kirkland (kirkland) ** Changed in: kvm (Ubuntu Intrepid) Assignee: (unassigned) => Dustin Kirkland (kirkland) ** Changed in: kvm (Ubuntu Jaunty) Assignee: (unassigned) => Dustin Kirkland (kirkland) -- qcow2 corruption regression https://bugs.launchpad.net/bugs/404394 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
