You mean QoS on memory bandwidth? It's an interesting question. (there are similar problems like QoS on shared L2)

I think it's hard to do.  Even for a native OS, it may only control this indirectly by adjusting the CPU time slice. And I don't think any commercial OS has implemented such feature yet.

Good Afternoon,

Is it possible to limit a guest OS to a specific memory bandwidth
allocation? The purpose is to stop one guest OS from saturating the
memory bus.

Thank you,

Robert
