Hi ying/guangrong, sorry to disturb you, I have a question to consult with you. For the x86 RAS, if guest OS happen machine check exceptions(MCEs) in page table, such as guest application's page table, what is the behavior for it? For normal data RAS error, host will deliver SIGBUS to Qemu, and Qemu will inject MCE to guest. but if the page table happen RAS error, host should not deliver SIGBUS, then guest will not know it happen error, for this case, what is the behavior for KVM, terminate the VM? I do not find the handling logic. Thanks! look forward your to reply.
