Hi Jasmin, See http://www.lowepower.com/jason/setting-up-gem5-fv4.14-rc3ull-system.html <http://www.lowepower.com/jason/setting-up-gem5-full-system.html> for an example of what I've done.
You can simply compile a kernel and build a disk image. It really isn't much harder than that. There are two gotchas: 1) making sure to compile without modules (compile all needed drivers into the kernel) and 2) disabling drivers that break gem5. There is a link on that page to a config file that has worked for me in the past. I've also successfully built and run v4.14-rc3 recently. The only other problem that I've run into is getting the init/startup process working correctly to get the gem5init script working. However, this is orthogonal to any gem5 issues. It's just that Ubuntu is using upstart (or whatever they are using now) and that is *incredibly* difficult to use. Hope this helps!
