QEMU 0.12.x has dropped support for kqemu. This has left users of system
with CPU without hardware virtualization support without possibility
to run QEMU with acceleration.
As it seems, there is no possibility to have kqemu support reintroduced to
the mainstream QEMU, I'd like to suggest keeping the older, ver.<0.12 QEMU
in another package (qemu-old, qemu-legacy, qemu-kqemu?) which could
installed in parallel with the new one.

this is unfortunate, yes...

it's too much maintenance, especially considering security bugs, to continue to
support an outdated branch of qemu.  we've already got qemu-kvm, which is at
least based on a very similar version, and xen-qemu* (not sure what version
it's based on).

as an alternative that doesn't require hardware acceleration, consider trying
virtualbox-ose.

live well,
