I run in an issue by the attempt to run example-kernels and hope to find help this way.
The cli cargo bootimage --target x86_64-bootimage-example-kernels.json finished successfully, but cargo xrun failed

Going to close the issue. Solved it by purging ~/.cargo directory and repeating the build procedure again.
p-alik commented
Going to reopen the issue because it's unresolved.

Update of the crate x86_64 and removing of build-std solved the issue.
