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...

要修改env->cpuid_model,先看看定义,在target/i386/cpu.h被定义成uint32_t cpuid_model[12],很合理,三个ID,每个ID 4个寄存器,一共12个uint32。 然后呢,还需要寻找一个string到uint32_t的转换逻辑,简单看了一下代码里有个x86_cpuid_set_model_id函数 ...

解决2:在主机 BIOS 中启用了检查虚拟化,同时将主机配置为载入 kvm 模块。 [root@hp ~]# virsh start control 错误:开始域 control 失败 错误:不支持的配置:域需要 KVM,但不可用。在主机 BIOS 中启用了检查虚拟化,同时将主机配置为载入 kvm 模块。
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。
