I'm using virt-manager to create a new vm. Virt-manager asks me "CPU
architecture" and "Hypervisor". When I select i686 as CPU arch I can not
select KVM as hypervisor, only qemu is offered.
If I understand you correctly, I should select x86_64 and KVM, even if I want
to run a 32 bit OS, right?
Isn't that counter-intuitive?
This has confused quite a few people in the past (including myself). We
should probably add some better wording in virt-manager or some kind
of note explaining the terminology, but no matter what way you slice it
it's still easy to get tripped up on the concepts.
