For i686 arch we look for the 'qemu' binary, followed by the 'qemu-system-x86_64' binary. This is not good with QEMU 1.0, since the 'qemu' binary was renamed to 'qemu-system-i386' and the 'qemu' name might be reused for another purpose later.
Make sure we look for 'qemu-system-i386', then 'qemu-system-x86_64' then the qemu-kvm binary. Only use 'qemu' as a very last resort
Should we be favoring x86_64 first? As I understand it: i686 host can use qemu-system-i386 (fast with kvm); I'm not sure if it can use qemu-system-x86_64 (but if it does, it won't be with kvm, so it will be slow) x86_64 host can use either emulator, and both will be fast thanks to kvm. I'm not necessarily opposed to your choice of ordering, but a bit more rationale in the commit message might help. At any rate, ACK. -- Eric Blake eblake@redhat.com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
