Chen, Thanks. I used the real platform to verify Cpu MP. It seemed that one AP is good but 3 APs still failed. Do you know what else need to consider? Or could you tell me your test environment?
1. -smp 4 faile, please see the attached log and console output $ sudo qemu-system-x86_64 -bios OVMF64.fd -smp 4 --enable-kvm -serial file:ovmf64_4.log 2. -smp 2 succeed, please see the attached log. $ sudo qemu-system-x86_64 -bios OVMF64.fd -smp 2 --enable-kvm -serial file:ovmf64_2.log For IA32 arch, I got the exact result. Thanks!
