Make sure the build VMs are dumbed down to bare x86-64 ISA support? IIRC qemu can handle this.
It's not that easy, because `cpuid' instruction is non-emulated, and available to unprivileged users IIRC, so if someone just uses it to determine what comands to use, it will still fail. (It might be that this is only true for Xen and not qemu/kvm, but I remember having real life problems because of this some time ago). -- Stefan Seyfried "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." -- Richard Feynman -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-packaging+owner@opensuse.org
