Hi Ralf,
I have downloaded the master branch and given make and I have got the
following error, I fixed the error with one of the reference link, but
didn't find the /dev/jailhouse post installation
ubuntu@ubuntu:~/jailhouse$ git branch
* master
ubuntu@ubuntu:~/jailhouse$make

ubuntu@ubuntu:~/jailhouse$
To fix the above I have followed the link
https://bbs.csdn.net/topics/615205697 and changed as per instruction, even
I followed the earlier build from this link only. but I was not able to
build jailhouse-image.
DTC_INCLUDE += /usr/src/linux-headers-5.4.0-1069-raspi/include added in
the file -->/usr/src/linux-headers-5.4.0-1011-raspi/scripts/Makefile.lib
After that I am able to install,
ubuntu@ubuntu:~/jailhouse$ sudo make install
