qemu/kvm in enabling the cloud is huge but that's not the only place it really makes a tremendous difference. One example where it's essential is new OS development. They all basically first target the qemu machine with its virtual hardware. It makes development much faster compared to running on real hardawre while easily enabling debug output without needing cables and the like.

Eh, we just used stuff like bochs and vmware prior.

I didn't mean qemu is the only option.

My point is that the appearance qemu/kvm didn't really practically change the space much.

Oh I understand what you're saying. You're probably right. Collectively virtualization allows a lot but qemu might not be as exclusive as I said. (I think there are only a few years between bocsh/vmware and qemu/xen.)

EDIT: I didn't mean to sound like ChatGPT. It happened naturally :)
