Public bug reported:
[impact]
The qemu-system-* binaries for most archs have a default machine type,
meaning no --machine needs to be specified. This is extremely useful
for situations running qemu on multiple archs in a common way, for
example what systemd's self-testing does.
On arm archs, there is no default, so --machine must be specified. It
would be better (i.e. qemu users would not need to include arch-specific
qemu parameters) if there was a default machine for arm.
[test case]
install qemu-system-arm, and try to run qemu without any --machine
specified.
Also, this command will show if there is any default machine defined:
$ qemu-system-aarch64 -M ? | grep default
[regression potential]
since no default is currently defined, all users of qemu-system-aarch64
or qemu-system-arm must currently define a machine type. This change
would (should) not have any effect on them, since it only sets a default
machine type for use when -M is not specified.
[other info]
I'm preparing a patch to send upstream and will add the link once sent.
