--- Comment #57 from Thorsten Kohfeldt <thorsten.kohfe...@gmx.de> ---
I have filed a bug against dracut:
https://bugzilla.redhat.com/show_bug.cgi?id=1067669
which gives an explanation at least for kernel 3.13.
That kernel version introduces multi queue block i/o for virtio_blk, which in
turn does not any more call blk_init_queue() but blk_mq_init_queue() instead.
Dracut matches against symbol blk_init_queue but not yet against symbol
blk_mq_init_queue.
This should be fixed for Fedora and also for all RHEL derivatives ...
In the mean time there is this WORKAROUND:
1) check if virtio_blk is in intrd:
# for i in /boot/initramfs-* ; do echo $i: ; lsinitrd $i | grep virt ; done
2) if virtio_blk is missing in the relevant initrd, then
# echo 'add_drivers+="virtio_blk"'
>/etc/dracut.conf.d/force-vitio_blk-to-ensure-boot.conf
(NOTE that the .conf extension is mandatory !)
3) then rebuild the initrd
