Bug Description
Binary package hint: kvm
Since the latest update to 1:84+dfsg-
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)
============
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.

The same here with 1:84+dfsg- 0ubuntu12. 1~rc5ppa1 (Backport) from https:/ /edge.launchpad .net/~ubuntu- virt/+archive/ ppa.
This was now problem with the old 1:62+dfsg- 0ubuntu8. 2 0 before the update.
KVM Host: 2.6.24-23-server #1 SMP Wed Apr 1 22:14:30 UTC 2009 x86_64 GNU/Linux
KVM Guest: 2.6.24-24-server #1 SMP Fri Jul 24 22:44:54 UTC 2009 x86_64 GNU/Linux
both ubuntu 8.04 LTS, only the host with the backport-repository for kvm.
Any suggestions what to do?
