Hi, I hope you have a good day! I have a question regarding Guest TLB flush IPIs. <quote> If the hardware does not support APIC virtualization: kvm_vcpu_kick sends an host-IPI to the remote vcpu if that vcpu is in guest mode, a VM-exit (exit reason: external interrupt) will be triggered due to the host-IPI. Then on VM-entry (inject_pending_event) the guest-IPI is injected. </quote> If that IPI is a TLB flush IPI, what will happen if the remote vcpu access the stale tlb entry before the host-IPI arrives? I really appreciate it if someone could shed some lights on this problem.
Thanks for your time!
