From fa3b6dcd5298db2e7b63c17795c9e5570d3df8d9 Mon Sep 17 00:00:00 2001 From: Yu Zhao Date: Fri, 8 May 2009 10:33:38 +0800 Subject: [PATCH] VT-d: fix invalid domain id for KVM context flush The domain->id is a sequence number associated with the KVM guest and should not be used for the context flush. This patch replaces the domain->id with a proper id value for both bare metal and KVM.
