Yes. qemu-i386 /crossroot/bin/bash will run an i386-based bash as a normal process, only emulating the CPU part, all system calls are made normally (with a bit of data translation). > Any idea when this could be useful beside (I guess) cross-building > platforms?

(we don't have a fixed set of archs which are built inside qemu-user) Samuel _______________________________________________ hwloc-devel mailing list hwloc-devel@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/hwloc-devel
