[RFC PATCH 0/1] tests/migration-test: Allow testing older machine types

[Fabiano Rosas <farosas@suse.de>]

Hi, I had this WIP patch laying around that seems to fit Juan's vision
about testing older machine types. It is a very rough draft for now,
but it may be useful for kickstarting the discussion.

With this we can give the tests two different QEMU versions. The test
picks the older machine type between the two and runs the whole
migration-test suite.

We'd just need a way to provide the older build. Currently I'm doing
this by hand.

sample output:
 # Using two different QEMU binaries. Common machine type: pc-i440fx-8.1
 ...
 # Using ./qemu-system-x86_64 (v8.1.0-952-g8a940312a2-dirty) as migration source
 ...
 # Using ../build-8.1.0/qemu-system-x86_64 (v8.1.0-dirty) as migration destination

Let me know what you think.
