I need to run WINE in 32 bit mode, on a 32-bit install in a VM. Is a 64-bit virtual cpu type recommended anyways? Are the "qemu" and "kvm" cpu types faster/slower? And what would they be listed as in the kernel .config? I'm not familiar with all the weird codenames for Intel's chips. What's the hierarchy between Nehalem/Westmere/SandyBridge/Haswell ? Here's the list of available types...
