Is it possible to run 64-bit binaries under 32-bit Linux without emulating a whole system? My hardware is 64-bit compatible (Intel Core 2 Duo). I thought I have found what I was looking for in qemu's usermode. Apparently it allows binaries from different architectures to be run like a native binary provided all the required libraries are installed (much like wine, except it supports many architectures). However, apparently the Ubuntu package of qemu does not contain the qemu-x86_64 binary/script. (while providing a qemu-system-x86_64 one that emulates a whole system)
qemu qemu-make-debian-root qemu-system-mips
qemu-arm qemu-mips qemu-system-mipsel
qemu-armeb qemu-mipsel qemu-system-ppc
qemu-i386 qemu-ppc qemu-system-sparc
qemu-img qemu-sparc qemu-system-x86_64
AFAIK the qemu-arch binaries are used to execute a binary of that particular architecture (like wine), while qemu-system-arch is used to emulate a whole system in that arch (like vmware).
Does anyone have experience with this?
