[Xen-devel] [PATCH] Add a mechanism to detect block device setup failure

[Murillo Fernandes Bernardes <mfb@xxxxxxxxxx>]

The problem is: There is no mechanism to detect block device setup failure

Network devices have the same problem, and are fixed with this too.

I handling this problem in the way suggested by aliguori: 
- hotplug scripts write a "hotplug-status" node on store
- Xend DevController.createDevice() check verify this node and return success 
or throw an exception on failure. 
- If no changes in "hotplug-status" node after DEVICE_CREATE_TIMEOUT seconds 
Xend throw an exception showing the problem with hotplug scripts.

Comments?

Regards
