Guest code is not part of QEMU. We don't say that SeaBIOS, SLOF, etc. are part of QEMU; it constitutes mere aggregation with the GPLv2 QEMU sources, so it _is_ possible to distribute APSL2 guest code with QEMU. IANAL, but I'm fairly sure about this. However I agree that LICENSE needs to be updated, something like this: diff --git a/LICENSE b/LICENSE index 0e0b4b9553..81b9b3572d 100644 --- a/LICENSE +++ b/LICENSE @@ -1,13 +1,18 @@ -The following points clarify the QEMU license: +The QEMU distribution includes both the QEMU emulator and +various firmware files.
