This patch adds logic to kvm/x86 which allows to mark an injected exception as reinjected. This allows to remove an ugly hack from svm_complete_interrupts that prevented exceptions from being reinjected at all in the nested case. The hack was necessary because an reinjected exception into the nested guest could cause a nested vmexit emulation. But reinjected exceptions must not intercept. The downside of the hack is that a exception that in injected could get lost. This patch fixes the problem and puts the code for it into generic x86 files because. Nested-VMX will likely have the same problem and could reuse the code. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Avi Kivity <avi@redhat.com> |
