[libvirt] [PATCH 4/4] qemu: default to kvm32/kvm64 when KVM is enabled

2012-01-23 Thread Paolo Bonzini
The qemu32/qemu64 models are weird in that the exact combination of CPUID flags does not match any actual processor. kvm32 and kvm64 are a better match when not using TCG. Use them when -cpu is only needed to hardcode a 32-bit guest arch or for kvmclock. Signed-off-by: Paolo Bonzini --- src/qe
