Berrang=C3=A9 When a developer's environment is already within a podman container it is not possible to use 'podman' again to create containers. It will usually result in wierd errors such as: Error: fatal error, invalid internal status, unable to create a new pause= process: cannot re-exec process to join the existing user namespace. Try r= unning "podman system migrate" and if that doesn't work reboot to recover Podman offers the ability to talk to a daemon outside the container, however, which could be leveraged by QEMU. This can be used by invoking "podman --remote", or equivalently the separate "podman-remote" binary: https://github.com/containers/podman/blob/main/docs/tutorials/remote_clie= nt.md The current 'podman version' check is insufficient to detect the inability to launch containers, so it is replaced with the stronger 'podman info' check.
