Thank you, the current code is quite old, it probably has lots of issues and needs a major update.

I never used -daemonize, what is it supposed to do?

[LnnrtS]

-daemonize should make it run in the background.

I was trying to use it for automatic testing from CTest. Without that feature I probably will need some intermediate tool to handle daemonization.

I don't know, perhaps it can be easily fixed. You can rebuild qemu and try that patch; if it is functional I can make a new release.

I tried the suggested patch, but it did not help.

Any other ideas?

I get this issue at docker container, but I don't at other situation. Is it help for you somehow?

[ilg-ul]

I suggest you try qemu-system-arm.
