Hello all,
I was measuring amount of time taken on host by the Xen toolstack
while launching a PV guest.
I notice that there is around 2-3 seconds of time spent on dom0 by
toolstack before guest starts executing. Significant amount of time is
taken in the function xc_dom_boot_mem_init, around
qemu can also access disks which will be provided with a qdisk backend
directly; add a flag to libxl__device_disk_find_local_path to indicate
whether to check for qdisk direct access.
Reorganize the qemuu disk argument code to make a clean separation
between finding a file to use (if any), and
Testing the hotplug external script path at the moment involves
actually setting up one of the alternate datapaths (blktap, iscsi,
c). Simplify testing by making a script which does a simple loopback,
but still has a target that can't be used directly.
To use:
Move pygrub checks for local access ability into a separate function.
