[libvirt] [PATCH 1/2] libxl: add acpi slic table support

[Marek Marczykowski-Górecki]

From: Ivan Kardykov <kardykov at tabit.pro>

Libxl driver did not support setup additional acpi firmware to xen
guest. It is necessary to activate OEM Windows installs. This patch
allow to define in OS section acpi table param (which supported domain
common schema).
