I think your case was fixed by f4ef19108608 ("KVM: X86: Fix loss of
pending INIT due to race"), but that patch didn't fix it
Hi Paolo,
What's your opinion about this patch? We found it just before finishing patches
for the past two days.
Thanks,

Let me clarify it more clearly. Time sequence is that qemu handles ‘query-cpus’ qmp
command, vcpu 1 (and vcpu 0) got registers from kvm-kmod (qmp_query_cpus->
cpu_synchronize_state-> kvm_cpu_synchronize_state->

sends
Hi,
We encountered a problem that when a domain starts, seabios failed to online a
vCPU.
After investigation, we found that the reason is in kvm-kmod, KVM_APIC_INIT bit
in
vcpu->arch.apic->pending_events was overwritten by qemu, and thus an INIT IPI
sent
to AP was lost. Qemu does this since
