[Qemu-devel] [PATCH] Mark legacy option '-no-kvm' as deprecated

[Thomas Huth <thuth@redhat.com>]

'-no-kvm' was just a legacy convenience option for the users of
qemu-kvm, it never made sense in the normal QEMU tree since TCG is
the default here anyway. The option has also never been specified
in the QEMU docs and in the '--help' list, so likely hardly anybody
knows about this option at all. I think we could get rid of this
without bothering anybody nowadays, but just in case, let's print
out a warning for a couple of releases first.
