Commit b5861e5c introduced a check on the interrupt-window and NMI-window CPU execution controls in order to inject an external interrupt vmexit before the first guest instruction executes. However, when APIC virtualization is enabled the host does not need a vmexit in order to inject an interrupt at the next interrupt window; instead, it just places the interrupt vector in RVI and the processor will inject it as soon as possible. Therefore, on machines with APICv it is not enough to check the CPU execution controls: the same scenario can also happen if RVI>vPPR. Fixes: b5861e5cReviewed-by:
