Only first 29 cores on each CPU show.

There are a total of 96 cores between my 2 CPU's, 48 cores each CPU, and only the first 29 cores show up on each CPU:
CPU(s) 96 x Intel(R) Xeon(R) Platinum 8168 CPU @ 2.70GHz (2 Sockets)

There doesn't seem to be a way to get it to show all 48 cores on each CPU.

Please provide sensor datadump (use the argument save-sensors-data).

[donaoneil]

Not sure what argument 'save-sensors-data' is as there is no such CLI argument according to the -h.

Here is the sensors output, looks like PVE might be limiting it to 29 cores:

If that's the lm sensors output, then that's the limiting factor.
