Q: can NUMA still work in a virtual machine?

A: it is possible to bind successfully, but it may not achieve the desired effect, depending on whether vm binds CPU itself. If vm binds the core itself, it is effective. If you bind the container in the virtual machine, the effect of CPU binding is the same as that of unbinding. If vm does not bind the core itself, it is useless even if it is bound. Of course, if the vm party provides the transparent transmission function and transmits all the NUMA information to vm, then it is effective to bind the container in the virtual machine.
