2012-01-08 Thread Alexander Graf
When running QEMU without -cpu parameter, the user usually wants a sane default. So far, we're using the qemu64/qemu32 CPU type, which basically means "the maximum TCG can emulate". That's a really good default when using TCG, but when running with KVM we much rather want a default saying "the max
