Public bug reported:

Anyone know why ubuntu utopic/trusty doesn’t allow to change nr_requests
and I/O scheduler for instance that is running on the cloud running
openstack havana?

echo 129 > /sys/block/vda/queue/nr_requests
-bash: echo: write error: Invalid argument


However values lower then 129 works. 

Thanks
