This request was evaluated by Red Hat Product Management for

Because the affected component is not scheduled to be updated

Red Hat invites you to ask your support representative to

Red Hat Enterprise Linux.
When switching drivers you need to rebuild the initrd with the new drivers before rebooting. You can do this by passing --with=virtio_blk to mkinitrd (you will probably also need virtio_pci and possibly others).
mkinitrd --with=virtio_blk --with=virtio_pci -f initrd-`uname -r`.img `uname -r`
