hey,

i was just trying to get a concrete answer about this the other day,
so maybe you can clarify because i keep reading conflicting and/or
outdated information.

AFAICS, qemu-kvm is still _different_ from upstream kvm support in
qemu, correct?  i tried rebuilding qemu several times, ensuring i had
all the options i wanted (SPICE/kvm/etc) and i was getting absolutely
<expletive deleted> performance -- switch to qemu-kvm and she's
blazing again, yet many places seem to suggest they are one and the
same.

i see they definitely have different sources, but would you/anyone
care to elaborate on the relationship?
