Hi, When running 'make menuconfig ARCH=uml' there is no 'Executable file formats / Emulations' menu. I guess this makes sense since I guess that only binaries that can be run on the host kernel can be run from UML. Does this mean that if a x86_64 host kernel supports IA32 emulation then 32bit binaries can be run from inside the UML instance as well? If so, does anything need to be enabled in the UML kernel config to support it? Cheers, Nick |

Basically you see the messages 1 by 1 from different instances,not that smooth. Though these are processes running in a ubuntu, should be multi-threaded. Is this expected to be so or it's just running slow ? thanks ! |

I'm not sure what you mean by "see the messages 1 by 1", but each UML instance runs as a separate Linux process (several "interwoven" processes, actually), so multi-threading does not play any role here.
