faild to make install

[charles king]

OS: debian 8.2

kernel version: 3.19.1

vmx future is on

kvm is on

the satuation:

    I make the jailhouse, and make firmware_install, and then make install the jailhouse according to the README.md file.But I found the device file not created in directory /sys/devices, and the make install has no error return, so does any one encounter this situation? And when I jailhouse enable, it is said: "opening /dev/jailhouse: no such file or directory".

    Need help.

    best regards
