The 2018 edition of the QEMU advent calendar 2018 featured Linux images

Let's also make sure that we build the corresponding machines in Travis,
and while we're there, drop the superfluous --python parameter (python3
is now the only supported version anyway).

Hi Thomas, let me check one thing...

The VM will be launched as:


ppc-softmmu/qemu-system-ppc -display none -vga none -chardev
socket,id=mon,path=/tmp/tmpvdokyvs3/qemu-41146-monitor.sock -mon
chardev=mon,mode=control -machine g3beige -chardev
-serial chardev:console -M graphics=off -kernel


Note that it passes '[..] -machine g3beige [...] -M graphics=off [...]'.
I suspect you wanted '-machine g3beige,graphics=off'. am I right?

No, the -M graphics=off was intended.

QEMU will interpret the -M option as a parameter of the already set
machine type?

That's exactly the case.

or the -M overwrites -machine, and because  g3beige is the
default type it just works?

No, the default machine of qemu-system-ppc is mac99.

I think you're wrong about the default machine type:

$ qemu-system-ppc -M help
Supported machines are:
40p                  IBM RS/6000 7020 (40p)
bamboo               bamboo
g3beige              Heathrow based PowerMAC (default)

g3beige is marked as default and seems to be created without any -M option but having two -M options e.g. -M mac99 -M graphics=off creates mac99 machine so multiple options seem to work as you described.
