[Qemu-devel] How to configure QEMU to support APIC virtualization

[ddm]

Hi guys, 


I have tried via modprobe kvmintel enable_apicv=Y  to adjust KVM parameter, but 
it doesn't effect,  and 
cat /sys/module/kvm_intel/parameters/enable_apicv always return "N". 
I don't know how to configure KVM or QEMU to support APIC virtualizaion feature?

Could you tell me how to configure it?


Thanks!
