User Mode Linux for Beginners – Setup and first VM
Why another UML tutorial?
This is not the first tutorial on UML — there are hundreds of them publicly available on the internet. However, none of them seems to fulfill my requirements:
- All my computers and servers (= UML hosts) run on x86_64, not on i386.
- Use an up-to date (self-compiled) UML version, so you can use the latest features
- One simple set of scripts. Execute them in the correct order to get it up and running – no config file editing etc.
- Root should not be required (disregarding debootstrap) —> No /mnt mounts or similar
- No nasty filesystem image that eats up space on the host and limits resources on the UML VM. HostFS eliminates all those disadvantages – if you want to limit VM space, use quotas.
- No global state (e.g. mounting sth into /mnt), you should get another VM up and running concurrently by executing the setup scripts in another directory.
- Step-by-step instructions, as automated and portable as possible, but still made to be read by humans.
- No expansive techtalk. There are reference documentations out there for techtalk. A tutorial should tell you how to get it working, not why it works.

You want to compile and install libc++ (sometimes also named libcxx), but CMake complains with this error message
CMake Error at cmake/Modules/MacroEnsureOutOfSourceBuild.cmake:7 (message):
libcxx requires an out of source build. Please create a separate</em>

VNC: Scale VNC window
Problem:
You want to view a VNC on a screen with a different resolution than the screen you’re viewing (e.g. you want to view your Full HD desktop display on your Notebook).
Usually VNC viewers show scroll bars, but in some cases you need to view the entire screen at once.
