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.

Description Jamie Bainbridge 2014-05-31 23:08:54 UTC 
+++ This bug was initially created as a clone of Bug #1067669 +++

Description of problem:

Dracut identifies kernel modules for block devices in
90kernel-modules/installkernel by a list of symbols.
One of the symbols is "blk_init_queue", which in the past lead to the inclusion of virtio_blk.ko for vm guests.
In kernel 3.13 virtio_blk calls the new function blk_mq_init_queue rather than blk_init_queue and thus the symbol match fails and virtio_blk is not included any more.

That way vm guests configured vor virtio_blk fail to boot kernel 3.13 unless virtio_blk is included for other reasons.

Please add symbol "blk_mq_init_queue" to the list of symbols next to "blk_init_queue" in 90kernel-modules/installkernel.

I was having a boot problem on my KVM guest that uses virtio (host=RHEL 6.5 and guest=CentOS 6.5, kernel 3.13). This bug report explains the cause quite well. I created initramfs with a '--add-drivers virtio_blk' option and the kernel booted just fine.

Comment 1 Jamie Bainbridge 2014-05-31 23:15:50 UTC 
This prevents ELRepo's kernel-ml from booting on EL6.

As Akemi Yagi noted in the Fedora bug, this can be worked around manully by rebuilding the initramfs with '--add-drivers virtio_blk' added to the dracut line.

As Thorsten Kohfeldt noted in the upstream bug, this can be permanently worked around with:

echo 'add_drivers+="virtio_blk"' >/etc/dracut.conf.d/force-vitio_blk-to-ensure-boot.conf

Please consider including this dracut change in RHEL 6 so that downstream CentOS can consume it, as the CentOS community is no doubt the largest consumer of ELRepo's kernel packages.

bug 1041484 changed to blk_cleanup_queue, which will pickup virtio_blk
