Message-ID: <1266493115-28386-5-git-send-email-joerg.roedel@amd.com> Date: Thu, 18 Feb 2010 12:38:29 +0100 From: Joerg Roedel <joerg.roedel@....com> To: Avi Kivity <avi@...hat.com>, Marcelo Tosatti <mtosatti@...hat.com> CC: kvm@...r.kernel.org, linux-kernel@...r.kernel.org, Joerg Roedel <joerg.roedel@....com>, stable@...nel.org Subject: [PATCH 04/10] KVM: SVM: Sync all control registers on nested vmexit Currently the vmexit emulation does not sync control registers were the access is typically intercepted by the nested hypervisor. But we can not count on that intercepts to sync these registers too and make the code architecturally more correct.
