From 11aff98c848255f5ed3c339915e5ddccb12d57fb Mon Sep 17 00:00:00 2001 From: Zhang Xiantao Date: Thu, 20 Dec 2007 19:34:38 +0800 Subject: [PATCH] kvm: qemu: Add one empty entry in hob to adapt the requirement of open guest firmware. Since open guest firmware use hard-code to check hob entries, so add one empty entry to workaround it.
