The (unofficial?) FAQ at http://uml.devloop.org.uk/faq.html implies that it is possible to build UML on a 64-bit system to run a 32-bit guest.
The best that I can manage on e.g. Debian "Jessie" x86-64 is to use make ARCH=um SUBARCH=i386 which results in a 32-bit ELF to presumably run a 32-bit guest. Prerequisites appear to be the multiarch-support and gcc-multiarch packages. Is it possible to build UML as a 64-bit binary, but to run a 32-bit guest? What I'd like to be able to do is to put it on a system which has no multiarch stuff, i.e. to completely sequester the 32-bit libraries etc. within the guest filesystem. [Background: I used UML fairly heavily in the 2.4 era, but I'm a comparative newcomer to x86-64. I'm trying to avoid overuse of multi-arch stuff.] -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ------------------------------------------------------------------------------ _______________________________________________ User-mode-linux-user mailing list User-mode-linux-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/user-mode-linux-user
