For ppc64 systems, it also depends on what class of arch it is presenting. I would expect a CHRP setup for ppc970, but I have no idea. If you send me an ssh pubkey, I can get you an account on a G5.

It's useful to be able to run Fedora on qemu-system-ppc, if only because it allows me to track down build problems that only affect the ppc builders. (Which in fact is what got me into this in the first place). Fedora ppc (32 bit) boots on qemu from git, but not our build of qemu (BZ 505109). Albeit without serial console[1]. I haven't been able to get Fedora ppc64 to do anything at all, neither with Fedora's qemu, nor with qemu from git. I'm not even sure I'm doing it right. Rich. [1] qemu-system-ppc emulates PC-style serial ports (ie. 16550A). The Fedora ppc kernel contains the right driver and prints a message indicating that ports are available, but for some reason nothing is actually sent or received. I guess that no real PPC hardware would have such serial ports. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones libguestfs lets you edit virtual machines.

Fedora PPC console=? to get serial console
(Posting here because the fedora-ppc list is a bit overrun with spam http://lists.infradead.org/pipermail/fedora-ppc/ ) Does anyone know what 'console=...' parameter I should give the Fedora PPC kernel to get it to use a serial console? Debian uses the non-standard form console=ttyPZ0 I've also seen console=hvc0 mentioned. Obviously I also tried console=ttyS0. None of the above seem to work ... I'm using qemu-system-ppc, not a real machine.
