ODAVP: OAKERR 7007 when starting a VM

When a VM fails to start with a similar error as below:

Attempting to start vm on node:0=>FAILED.
<OAKERR:7007 Error encountered while starting VM - Error: Device 51728 (vbd) could not be connected. Hotplug scripts not working.

It may worth a try changing the below parameter

(device-create-timeout 150)

In the file below

/etc/xen/xend-config.sxp

And restart the oda_base.
