I mean. I cant use qemu on that I5 cpu because is slow without kvm. Kvm does not work on that cpu because it is needs some extensions from the cpu that there arent. Bhyve is the only alternative because it is a mix between qemu and kvm in terms of speed. So. My question is : how much old cpu there are that cant run kvm ? I dont think mine is the only one. May be a good idea is to port bhyve on linux to cover the little needs of the users who wants a fast hyp on the old cpus. and not,qemu in these cpus is very slow. is not the solution. I really think there isnt any better alternative than qemu in these situations. The only one is bhyve if someone wants to try the scenarios that im talking about,they will understand for sure. and maybe they want to start the porting of bhyve on linux.
