Version 2.22 was released in Sep 2009, so coming up for 9 years old now.
At some point we should to declare that platforms shipping >= NNN year
old versions of software are not a desirable target for QEMU. What is
our desired NNN value - 9 years feels awfully long to me.
For libvirt we recently decided to become more aggressive[1] in culling old
distros as supportable targets, declaring we'll only support non-EOL
distros (for short life distros), or for long life distros (RHEL, LTS, etc)
the most recent version, and the recent minus-1 for 2 years overlap.
Should we formalize similar guidelines for QEMU to give developers a
guide for when it is reasonable to increase the min required version of
any 3rd party library ? glib is a mandatory dep, but we've countless
other optional libraries we might wish to increase min versions for too,
and no guide on when it is reasonable todo so.

Daniel
