Configure the CPUs assigned to Proxmox

[tom_chbn]

Hello,
I have promox, and I have the following processor: Intel Xeon D-1521, But Promox only detects that I only have 2 threads when I have 8. So I would like to know how to modify this, I have already looked a little on the forum, but found nothing .
I attach you a screenshot of Iscpu
Please help me or direct me to adequate documentation.
Thank you in advance for your reply.
Sorry for English, I'm using Google Translate

Your screenshot shows 8 threads (2 threads/core * 4 cores). It looks correct for a D-1521.

However, there should be 8 threads as seen on the processor specifications

All Intel CPU's that support hardware threads have 2 threads per core. So there are 8 total threads on a D-1521, which is exactly what your screenshot shows. The cpu specifications you outlined in red means total cores = 4, total threads = 8, which is 2 per core, which agrees with your lscpu output.

I have a D-1541. It has 16 threads and this is my lscpu output:
