I think that's a red herring. Of course there are advances in
virtual hardware for those who need the best performance. But
there's also qemu's ability to provide to you a 1981-vintage PC (or
more likely a 2000-era PC). That's not going away.
So Red Hat dropping support for the pc type (alias i440fx)
https://bugzilla.redhat.com/show_bug.cgi?id=1946898
And the QEMU deprecation schedule
https://www.qemu.org/docs/master/about/deprecated.html
showing it as deprecated after 7.0 are wrong? That's not to say
virtualization can't help at all; it can certainly lengthen the time
horizon, it's just not a panacea.
deprecated.html says:
pc-i440fx-1.4 up to pc-i440fx-1.7 (since 7.0)
^^^ ^^^
These old machine types are quite neglected nowadays and thus might have
various pitfalls with regards to live migration. Use a newer machine type
instead.
Unless the qemu documentation is severely misleading, that does not
include pc-i440fx-{2-8}.{0-12}, and there is no indication that the
machine type "pc" (current alias of pc-i440fx-8.1) has been deprecated.
