QEMU / KVM virtualization supports two ways to configure CPU modelsHostpassthroughThis passes the host CPU model features, model, stepping, exactly to the guest. Note that KVM may filter out some host CPU model features if they cannot be supported with virtualization. Live migration is unsafe whe...

每个hypervisor对于guest能看到的cpu model定义都不同,Xen 提供host pass through,所以guest能看到的cpu和host完全相同。 QEMU/KVM中guest能看到自定义的通用cpu model “qemu32” or “qemu64”,而VMWare 要高级一些,它把host cpu划分成组,guest 能看到每组的baseline CPU model,这样guest就能在改组迁移。
