I wonder is this the case when vcpu is not in vm86 mode too? For vm86 we can change:
else reason = TASK_SWITCH_CALL; to else if (vcpu in vm86 mode) reason = TASK_SWITCH_GATE; else reason = TASK_SWITCH_CALL; IIRC you can't change tasks by call in vm86 mode. -- Gleb. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
