Default kqemu - useful?

On a machine with hardware virtual support, currently using qemu-kvm
for VMs, is there a use for kqemu at all? And is it still useful to
improve support on machines which lack hardware virtual, such as p4 and
similar?

I was a former user of qemu/kqemu before the merge of QEMU/KVM in F11,
according to bug #520284 [1] the upstream said that kqemu is unmaintainable.

Given that RPMfusion still offers it, I would say that the developers have the
latest hardware and the budget that implies, and regard two years old as not
worth supporting.

Helps greatly. The hardware we got three years ago which ran fine up through FC9
and which was specified particularly to run Linux now has had xen, kqemu, and
older Radeon support removed by the time we got to FC13.

Fedora is cutting edge, replace the distro every six months, obviously replace
the hardware at that time, too. Time to go in another direction.

Actually, it has nothing to do with that but a poorly maintained
codebase.

I think we are saying almost the same thing. The codebase is poorly maintained
because the people working on the drivers are not spending time testing changes
to see if they break old cards. I assume the developers have the latest because
(a) they are adding features using the 3D features, and (b) if they were using
the 2-3 year old cards they wouldn't be developing anything, because they would
be running in text or VESA mode.

I think you may be confusing your frustrations over kqemu and nouveau
with each other..
