Date: Wed, 26 Aug 2009 13:29:53 +0300 From: Avi Kivity <avi@...hat.com> To: kvm@...r.kernel.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH 31/47] KVM: SVM: check for nested VINTR flag in svm_interrupt_allowed From: Joerg Roedel <joerg.roedel@....com> Not checking for this flag breaks any nested hypervisor that does not set VINTR. So fix it with this patch.
