Hi,
Add to that shortcuts like -cdrom stop working,
Maybe is fixable.
Already fixed for ages.
I see marking Q35 as the default machine a first step.
Maybe the better option is to go the arm route: Just don't define a default, so users have to specify pc or q35. That will make them notice there is a world beside 'pc', and we also avoid breaking things silently.
If QEMU removes the default, then libvirt will have to hardcode 'pc' as the default to maintain back compatibility, so I don't think that ends up as a net win
I believe there's consensus that applications blindly relying on the default machine-type when creating a domain is a bad idea. That said, can we deprecate this feature in libvirt, encourage applications to always specify an explicit machine-type, thus making it possible to deprecate the i440fx machine-types one day? -- Eduardo
