Missing /dev/kvm while kernel module kvm.ko and kvm-intel.ko are both loaded [closed]

Question

The uname -a shows:

Linux localhost 2.6.39-gentoo-r3-nsfocus+ #52 SMP PREEMPT Wed Feb 12 15:37:56 CST 2014 i686 Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz GenuineIntel GNU/Linux

And I have already open the Intel VT on BIOS. The /proc/cpuinfo file content:

flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx rdtscp lm constant_tsc arch_perfmon pebs bts xtopology nonstop_tsc aperfmperf pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr pdcm sse4_1 sse4_2 x2apic popcnt aes xsave avx lahf_lm arat epb xsaveopt pln pts dts tpr_shadow vnmi flexpriority ept vpid

When I run qemu, the output is:

>./qemu-system-x86_64 -smp 1 -m 1024 -enable-kvm -vnc :1 -usb -usbdevice tablet -hda /opt/nsfocus/sda1/win2008r2.qcow2
Could not access KVM kernel module: No such file or directory
failed to initialize KVM: No such file or directory

I already have tried compile kvm and kvm-intel into kernel instead of as kernel modules, the result is the same.

Try to add it manually:

mknod /dev/kvm c 10 232
