Am I right in thinking that -display none vs -nographic has *no* effect
on guest machine ABI ? I think we're safe based on my reading of it,
particularly since we use -nodefaults and -nodefconfig, but want to confirm
there's no edge case i'm not aware of.
Regards,
Daniel

It changes one fw_cfg field from 0 to 1, but only OpenBIOS looks at it
right now.

Ok, that's fine as PPC doesn't have versioned machine types anyway, so
its migration compat is doomed regardless :-)

Just to obey the formal side of the process, ACK series.
BTW: there are lots of '-nographic' in our
tests/qemuxml2argvdata/qemuxml2argv-*.args files, do we want to update
those to have '-display none' instead?

I just realized, that you might not have the push rights, so I went
ahead and pushed these.

Possibly, but to do that you'd have to add the capability to all the
tests. It would be irrelevant for most tests, which test disk XML and
the like.
