The project has a mix of licenses, for mostly historical reasons.
The overall license is thus GPLv2 (as the most-restrictive of the set).
Our preference (as noted in the top level LICENSE file) for new
code is for GPL-v2-or-later; we can take other GPL-2-compatible
licenses (preferably GPL-v2-or-later compatible) if there's a
good rationale from the submitter. (Historically, one reason
for the GPL-v2-only code has been "this came from the Linux
kernel and so it's GPL-2-only"; "we copied a lot of this code
from some other file in QEMU and that has license X" is
the other one.)
