Makefile error : chmod: cannot access '/dev/qcuda': No such file or directory

I am trying to "make" the "qcu-driver", it throws me below error

vm2@vm2:~/test_appl/src/qCUDA-master/qcu-driver$ make i
[sudo] password for vm2: 
sudo rmmod qcuda
sudo dmesg -C
sudo insmod qcuda.ko
sudo chmod 666 /dev/qcuda
chmod: cannot access '/dev/qcuda': No such file or directory
Makefile:25: recipe for target 'i' failed
make: [i] Error 1 (ignored)

Do I have to make a device file name "qcuda" in /dev directory, if Yes, then what should be the parameters??
I understand that the source code is using misc device to create a device file in /dev directory. Just for the info, the kernel module qcuda.ko is created and launched without fail. However the misc device "qcuda" is not created in /dev directory. @coldfunction @rlmh @ginsongsong @good5dog5

@SusmitaDey You need to add the -device virtio-qcuda-pci parameter

Hi, what the parameter should be? I have used '-device virtio-qcuda-pci' without any parameter, but can not found the device in the guest os with command lspci.
