Re: [libvirt] [Qemu-devel] [RFC PATCH 0/2] ARM: add QMP command to query GIC version

I didn't say it would be hard :) I just said that such compatibility code would have to be kept around forever. We already support lots and lots of similar cases in libvirt, the difference being that in this case we would add support for a new command *knowing in advance* that it will become obsolete as soon as a proper implementation is available. It might still be the right thing to do! I just want to make sure everything's been properly considered and discussed beforehand.
