Hmm does it not boot? Do you get any errors?
a
In the web web ui i cannot select the arm architecture and i guess that the x64 image is unusable in VmWare for example. When i tried to build the ISO and download and boot it does not boot. So that is why I am trying the ARM image currently
w
I think you need to add an OS-version pointing to the Dev/arm64 repo to be able to build an arm64 iso from the ui.
a
What I have done now is add an export like this 
export REPO=dev
And then execute the registration injection. But somehow the xorriso is hanging or taking long.

What version of xorriso are you using?
For reference I'm using 1.5.4:

I am following the example in the documentation: https://elemental.docs.rancher.com/rancher-vmware/ and using the 
elemental-iso-add-registration
script that is provided. It downloads the correct image variant when setting 
export REPO=dev
but when executing the script it hangs on the steps involving 
xorriso

Its used the same version that you mention! 1.5.4
The result when running the scripts are: • Hang on xorriso • Total hangup of Docker (new shells do not respond any more to a simple 
docker ps
for example
w
Hmm, wonder if it's something with the docker volume
a
I also switched to Rancher Desktop from Colima as I expected that Colima was having issues but this also gives the same result
w
I tried running on a gcp arm64 machine and there of course it works.. =/

Do you have the output of 
docker info
Also, does it still hang without the volume-mounts in 
$CONT_ENGINE run --rm -v ${TEMPDIR}:/mnt -v $(pwd):/output ${BUILD_IMG} ...

Need to reboot.. brings my machine into a state that i cannot get any docker command working

Going to check without the volume mounts

Elemental web UI is x86_64 only (mainly because ARM64 isn't an officially supported platform yet)
a
After some testing it is indeed related to the mounted volumes. I modified the script a bit to copy in the original iso and then perform the injection and copy out the modified iso and that seems to work without any problems.

Nice! Pretty weird that the volumes don't work though...
