[Slackbuilds-users] RFC: qemu and aqemu

hope anybody don't mind if I share some thoughts on this :D

I have the qemu-system-x86_64 binary linked to just "kvm", for using
it with libvirt: I know it's another example of Red Hat
customizations, but I remember a discussion of not much time ago on
LKML in which Pekka Enberg renamed his new in-kernel kvm emulator
kvm-tool to follow this "standard"...

this way is also automatically found

I think the present state is optimal: qemu-kvm should be used in every
case kvm processor extensions are available, while qemu can be useful
in the few cases of needing virtualization on old processors (it's
very uncommon today to have x86 processors with no virtualization
extensions); frankly, I see no cases in which the use of both can be
useful...

my 2 cts :)
