Really have to replace -enable-kvm? Can't you keep compatibility for it?
We don't have to , but I'd rather deprecate it. I don't feel strongly, though.

It needs to stay.

For enabling/disabling, if you don't like -enable-kvm, I'd suggest thinking about modeling it through CPU. For instance:

-cpu host,accel=kvm|tcg|kvm,tcg

Since we already specify CPU's in a global config, if you took this approach, it would make it possible to tweak the default kvm vs. tcg selection within the config file so a user could control whether vms were created with tcg or kvm by default or whether it tried kvm and then fell back to tcg.
