They would not be difficult to implement (500 lines of code or so at most I guess), but on the other hand they've been unimplemented for some years. They fall into the category of "nobody who wants them has cared enough to write the code yet", I'm afraid. -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1591611 Title: chroot using qemu-x86_64-static fails on ppc64el Status in QEMU: New Bug description: When attempting to use qemu-x86_64-static from qemu 2.5.0 on a ppc64el host to chroot into an amd64 environment, all commands fail with an assertion error. /usr/bin/qemu-x86_64-static from the host was copied into the chroot /usr/bin, and the host has multiformat support in the kernel.
