I actually think putting this in -smp makes more sense. -cpu really shouldn't need to be touched by normal users and as long as you can either -cpu host or -cpu safe that should be enough.

Maybe. But in that case -cpu core2duo should imply cores=2 and -smp 2 -cpu core2duo will bring up 4 cores spread across two sockets.

But then again maybe we should replace -smp with something more useful like -numa where you'd then specify #CPUs, #cores, mem-cpu connection, etc.

I'd prefer -numa to specify the memory topology (and connections of sockets to memory nodes), and -smp or -cpu to specify the intra-socket topology.
