Got some harmless errors when checking virtio qcow2 image after running kvm autotest 'ioquit'
Last modified: 2010-11-09 07:51:46 EST
Description of problem:
Run kvm autotest 'ioquit' with virtio + qcow2 format image, will failed during checking image got some errors like this:
ERROR cluster 1617900 refcount=1 reference=0
Sometimes can find many such kind of errors though image is not corrupted.
Confirmed with Kevin, these errors are harmless besides wasting some disk space for guest.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run autotest kvm subtest 'ioquit'
(This test mainly runs dbench within guest and during dbench is running in guest, kill the autotest process along with all its child-processes including 'qemu-kvm'.
Got some errors though they are harmless
Should not got these harmless errors if image is actually not corrupted.
Maybe let qemu-img fix this or replace 'Error' with 'Warning' as Kevin referred.
