If guests can have different endianness (reasonable on some CPUs where it's switchable - some even have more than 2 options), then I guess the *host* on those systems have different endianness too. Is the host's endianness signalled to the guest anywhere, so that guest drivers can do cpu_to_qemuhost32(), when someone eventually finds that necessary? -- Jamie
