Fixed In Version: libvirt-1.2.17-13.el7_2.6
Doc Type: Enhancement
Doc Text:
This update introduces the ability to pass an advanced configuration and power interface (ACPI) table containing system-licensed internal code (SLIC) information to a guest. To do so, add the following element to the <os> section of the guest's domain XML file, where PATHNAME is the full path name of the ACPI table file: <acpi> <table type='slic'>PATHNAME</table> </acpi> As a result, if the guest's OS previously required reactivation due to missing SLIC information (such as Microsoft Windows does), it will now be properly activated.
