Error when emulating linux/amd64 on linux/s390x host

  "supported": [
    "linux/s390x"
  ],
  "emulators": [
    "qemu-aarch64",
    "qemu-arm",
    "qemu-i386",
    "qemu-mips64",
    "qemu-mips64el",
    "qemu-ppc64le",
    "qemu-riscv64",
    "qemu-x86_64"
  ]
}

First, install all platform; then run the container for linux/amd64,

linux1@t1:~$ sudo docker run --privileged --platform=linux/amd64 \
    --restart=always -itd \
    --name warp_one \
    --sysctl net.ipv6.conf.all.disable_ipv6=0 \
    --cap-add net_admin \
    -p 14888:9091 \
    -v /lib/modules:/lib/modules \
    ubuntu:focal

However, it wont start as it should be, it just keep restarting; actually same commands work when using the ARM platform, but it failed to run on S390x this time.

linux1@t1:~$ sudo docker ps -a

Looks like one update 3 days before fuck up the whole emulate... Today, I found the ARM one failed to do the same task, sad :(

For ARM machine, I found a solution: just use docker run --privileged --rm tonistiigi/binfmt:qemu-v6.2.0 --install amd64 rather than docker run --privileged --rm tonistiigi/binfmt --install amd64.

However, the S390x still not work.

You haven't included any indication of what syscall fails. If you can trace it to syscall and it is a QEMU regression you can report it in their tracker. It is possible that it is not a regression bug though and somebody just fixed missing error handling in the previous version.
