File 077c9a25-intro-virDomainGetLaunchSecurityInfo-API.patch of Package libvirt.10924
commit 077c9a25049b38dd08e43b6ed4feaaf100f78336 Author: Brijesh Singh <brijesh.singh@amd.com> Date: Fri Jun 8 09:40:59 2018 -0500 libvirt: Introduce virDomainGetLaunchSecurityInfo public API The API can be used outside the libvirt to get the launch security information. When SEV is enabled, the API can be used to get the measurement of the launch process.
