The ISC license is more permissive than GPLv2+ and compatible with it. The file uses this license for history reasons: initial versions of it used to be part of the OpenBSD ports repository, which uses ISC. If ISC is not appropriate for qemu, I agree to use GPLv2+ instead (I'm the author this file).
