Hi Daniel,
I agree that to expose othe level cache but the only can be tuned (allocation). If we
expose such kinds of information, the host should have ability to control such kinds of
resources.
In another thread, Martin told that there are cases which multiple sockets may has
different values, I kinds of agree(but I don’t see that case), I agree to expose cache per
socket, just wonder if
cell == socket in libvirt? In my environment, I can see all socket_id in a cell are the
same, wonder if I can extend cache information to cell node?
No, cell == NUMA node. There can be multiple sockets per NUMA node. If you
see multiple CPUs with the same socket_id, this indicates they are cores
within the same CPU socket.

Daniel
