This article mainly shows you "how to achieve the host CPU feature of the KVM virtual machine", which is easy to understand and clear. I hope it can help you solve your doubts. Let me lead you to study and learn this article "how to realize the host CPU feature of the KVM virtual machine".
When using kvm virtual machines, it is often found that some physical cpu instructions are not supported. For example, when using centos6, it is found that the default CPU configuration of kvm xml configuration is that in order to better squeeze the performance of physical machines, we configure virtual machines to use the same cpu features as physical hosts.

2 obtain the cpu feature of the host
Virsh capabilities
3. Copy the parts in the figure above to a xml file, for example: test.xml
X86_64 SandyBridge Intel
4 calculate cpu-baseline CPU
Virsh cpu-baseline test.xml
5 copy the part to the virtual machine xml configuration file, open virsh, use edit to edit the xml configuration file, and add it to the entry
Virsh # edit test_kvm.xml
6 restart the virtual machine
Virsh reboot test_kvm
7 after adjustment
