[uml-user] Running 32bit binaries in a 64bit uml kernel

[Eric Dacquay]

Hi,

I've been playing around with uml these past few days and I was
wondering if it was possible to run a 32 bit binary under a 64bit uml
kernel.  I've got no issues running 64bit binaries but I've had no
such luck with the 32bit binaries.  If it is possible, I assume the
kernel needs to be configured correctly.  If this is the case, could
anybody point me to what this option is?

Thanks

Eric

My understanding of this and as far as I can tell is that all this
does is build a 32 bit kernel but this does not help what I am trying
to do.  What I'm wondering if it is possible, is running a multilib
setup inside uml.

Thanks

Eric
