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?

My host infos are as follows:

Could you tell me how to configure it?
