(Some of the pieces are there for it but we have no board that needs it.) Also, you should read up in the ARM ARM about the differences between old style BE32 and new BE8. (The quick summary is here: http://translatedcode.wordpress.com/2012/04/) What you're trying to do here is enable old-style BE32. This is not supported on any ARMv7 or later CPU, which means it does not overlap at all with virtualization support. We probably do care about BE8 big-endian guest support testing. (kvmtool can run guests in this mode; QEMU doesn't currently). thanks -- PMM -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
