Do you mean SLES 11, RHEL 6 or Ubuntu 12.04 are likely to get the
latest upstream libvirt release as a vendor update?

I tend to agree with Peter when he says that people stick with older
versions of software because they have a working setup and don't want
to risk it breaking, and replacing vendor-provided system components
with manually compiled upstream releases kinda goes in the opposite
direction :) I would definitely never have risked anything like that
in my previous life as a system administrator.

And of course we want to support way more than just RHEL and related
distros: this is about making the support shallower, not narrower :)

Cheers.
