RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
* Previously, a counter variable was not correctly reset when restarting an allocating request for disk images using the qcow2 format, which resulted in corruption of these disk images in the cluster allocation code in some cases. This update changes the way that the number of available clusters are counted in the qcow2 format, and qcow2 disks are no longer corrupted in the described scenario.
Reproduced this issue on qemu-kvm-0.12.1.2-2.355.el6 at the first time attempt. Verified the bug with qemu-kvm-0.12.1.2-2.355.el6_4.7 for twice, all passed.
Steps:
0. Make sure host has 100GB+ free disk.
1. Download
http://people.canonical.com/~arges/lp1189926/lnv-382.tgz
2. Uncompress the lnv-382.tgz
3. ./create-disk
4. Modified "test-kvm" and replace command "kvm" to "/usr/libexec/qemu-kvm".
5. ./test-kvm
I will upload the attachment for detail logs for both reproduction (failed) and verification (passed) cases.
