Description Thorsten Kohfeldt 2014-02-20 20:14:13 UTC
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.

Comment 1 Akemi Yagi 2014-02-21 08:03:27 UTC
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.
