Hi! Attached patch moves PAUSE instruction intercept handling into svm_vmexit_do_pause() analogous to the other instruction intercepts. In svm_vmexit_do_pause() update the instruction pointer. This fixes strange PAUSE intercepts on UP guests. Signed-off-by: Christoph Egger <Christoph.Egger@xxxxxxx> P.S.: This bug has been found with nested virtualization. -- ---to satisfy European Law for business letters: Advanced Micro Devices GmbH Einsteinring 24, 85609 Dornach b.
