Problem

i try to start an AMR machine and UI segfaults and if i created (only some cases) just set to kvm and dont allow to set my dessired machine.

WHY?

the UI does not know that all arches can be emulated but not all arches can be used KVM, please use this document cos oficial QEMU documentation is so obscured and complicated ( there is already documented but not pointed explicit)

host/guess i386 amd64 armv6 armv7 aarch64 observations
i386 KVM(*) KVM(*) TCG TCG TCG only if common hardware is present, otherwise TCG
amd64 KVM(*) KVM(*) TCG TCG TCG only if common hardware and host is more recent rather guess, otherwise will be TCG
armv6 TCG TCG KVM(*) KVM(*) KVM(*) only if host is a more recent cpu rather than guest
armv7 TCG TCG KVM KVM KVM(*) only if common hardware and host is more recent rather guess, otherwise will be TCG
aarch64 TCG TCG KVM KVM KVM(*) only if common hardware is present, otherwise TCG

HINTS

not all arches can be emulated if guest target cpu/arch features are superior to host ..
