+Subject: [PATCH] x86/pvh: disable posted interrupts
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Enabling posted interrupts requires the virtual interrupt delivery feature,
+which is disabled for PVH guests, so make sure posted interrupts are also
+disabled or else vmlaunch will fail.
