Subject: [PATCH] qemu: process: SEV: Relabel guest owner's SEV files created
c480ed
 before start
c480ed
c480ed
Before launching a SEV guest we take the base64-encoded guest owner's
c480ed
data specified in launchSecurity and create files with the same content
c480ed
under /var/lib/libvirt/qemu/<domain>. The reason for this is that we
c480ed
need to pass these files on to QEMU which then uses them to communicate
c480ed
with the SEV firmware, except when it doesn't have permissions to open
c480ed
those files since we don't relabel them.
