Concerning QEMU, could we maybe simply emit a warning a la

currently running the the 'pc' machine type. Please note that

versions of QEMU might use the 'q35' machine type instead. If you
require the 'pc' machine type for your setting, then please specify
it with the -M option."
Warnings tend to get ignored until things are actually break, so I
don't think this helps much. I think simply not having a default
machine type (as already suggested elsewhere in this thread) is the
best way to deal with this.
I would absolutely hate this. One of the nice things about qemu has
always been that 'qemu disk.img' is enough to start a simple VM. You
only need to touch any other options for things you care about. I
wouldn't want to give this up.
I agree. Don't change anything, leave "-M pc" aside, and let libosinfo
pick q35 for newer guests.
