[Xen-devel] e820_host default value and libxl (not xl)

Hi, According to xl.cfg(5) " This option defaults to true (1) if any PCI passthrough devices are configured and false (0) otherwise." And indeed this behaviour is implemented in xl. But not in libxl, which means other libxl based toolstacks (libvirt) will not take advantage of this directly.
