For riscv64, s390x, ppc64, I build in emulated virtual machines. The three emulated OS work correctly when running qemu manually and the project is correctly built. + +Now, I want to automate the process in a script: for each target architecture, boot the VM (start qemu as a background process), connect to the VM using ssh, build the software, collect the binaries, shut down the VM. + +Starting the same qemu command as used interactively as a background process with `&` does not work and fails immediately, apparently because of the lack of stdin. So, I added option `-daemonize` (and removed `-nographic` because an error message says the two options are incompatible). + +Using `-daemonize` instead of `-nographic`, all qemu command immediately fail with the following error: + +``` +objc[1141]: +[__NSPlaceholderDate initialize] may have been in progress in another thread when fork() was called. +objc[1141]: +[__NSPlaceholderDate initialize] may have been in progress in another thread when fork() was called.
