Yes, you can change the balloon target on the fly, so this isn't something
we need to keep as stable across migration. The question though is whether
libvirt/QEMU will correctly handle the changed balloon setting during
migration. ie does libvirt correctly issue a 'balloon' monitor command on
the target host if it has changed in the target XML ? If it does, then I
agree this check can go..
I think qemu should handle this just right as we pass it via the
monitor, but I didn't actually try it. I'll hold off this one until I
make sure that it actually is okay.
