[Xen-devel] [PATCH for-4.6] libxl: increase hotplug timeout to 40s

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

The default libxl timeout for hotplug scripts execution is too low, when
launching 40 HVM guests in parallel, all using the same file as disk,
execution times of ~20s are expected. Increase the timeout to 40s in order
to be sure hotplug scripts have enough time to execute.
