[Xen-devel] [Patch] tweak error reporting for bootloader errors in xm

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

The xm command does some basic validation of the 'bootloader' parameter
before trying to run it, however, the level of detail reported isn't as
clear as it could be.

For example if I typo the bootloader param it says:

  # xm create XenGuest1
  Using config file "XenGuest1".
  Error: Bootloader isn't executable

The attached patch makes it do an explicit check for path existance prior
to the one for executable permissions. It also prints out the path being
tested.

  # xm create XenGuest1
  Using config file "XenGuest1".
  Error: Bootloader '/usr/sbin/pygrub' does not exist

Regards,
Dan.
