Avi Kivity bd3d1ec3d2 KVM: SVM: check for progress after IRET interception ... When we enable an NMI window, we ask for an IRET intercept, since the IRET re-enables NMIs. However, the IRET intercept happens before the instruction executes, while the NMI window architecturally opens afterwards. To compensate for this mismatch, we only open the NMI window in the following exit, assuming that the IRET has by then executed; however, this assumption is not always correct; we may exit due to a host interrupt or page fault, without having executed the instruction. Fix by checking for forward progress by recording and comparing the IRET's rip. This is somewhat of a hack, since an unchaging rip does not mean that no forward progress has been made, but is the simplest fix for now.
