Hmmm - that "supported" attribute is something I hadn't noticed
before. Does this mean <mode name='maximum' supported='no'> is
possible in qemu capabilities? A quick scan of the libguestfs code
seems to show we don't cope with that.
It will be possible for QEMU versions prior to 2.9.0, as they dont
support "-cpu max". Some architectures may not support this too.
At least ppc64, aarch64 and x86-64 and s390 do.

Daniel
