|Some quick operational notes for users of loop and nbd devices|
A quick note for OpenStack operators -- if you are using loop or nbd devices to mount disk images in nova-compute, then you would be well served to have plenty of device files hanging around to reduce contention. For loop devices, that seems as simple as making more of them with MAKEDEV. With nbd, you'll also need to increase the value of the max_nbd_devices flag to nova-compute. The latter is improved in grizzly, where we will autodetect nbd devices.
