Hi,
I just did a commit: https://github.com/hugusmaximus/sel4webserver/blob/master/README.md
so people can test this project without having to use a Odroid-XU4 (myself I had this problem...).
Notice that I worked on this repository because in the below tutorial:
https://docs.sel4.systems/Tutorials/camkes-vm-linux.html
I was failing all the time at running in qemu the x86_64 image. Not sure what was happening there, I fixed many things but still not working, maybe because my laptop is somewhat old (Latitude E6410), and even if VT-x is supported for some reason I was unable to make it work (fixed BIOS disabling trusted execution, had OS nested guests supported, etc).
As I think having "easy things to play" is key for people to test seL4 stuff, I think it would be nice to make extra effort to have things working on user available equipment (x86_64, qemu, etc).
Having said that, I excuse myself in advance for any mistakes in the pull request process as this is the first time in my life doing this, so any suggestion and corrections will be welcome.
Last but not least important I'm very happy to have a working Linux guest on a seL4 running on my laptop as this opens to me a big door for tests so I can build prototypes and test many things hoping that as soon as possible I will have some developer doing this job and building native apps for seL4 to interact with an (isolated) guest.
Cheers,
