how to get cpu correct frequency in pve vm client ?

[cpakest]

I have installed PVE 8.0.3 in my pc and created a vm client to run windows 7 . But i can't get the correct cpu useage in windows with cpu-z , just like this:

The cpu freq is aways display "806.00mhz" with no change when it running some software.
But at the same time , PVE can get the right status when i type " cat /proc/cpuinfo " at PVE's shell.


Do i miss somethings ?

You mean frequency, not usage.

Why is having the correct frequency so important to you?

i'm sorry for my pool english , that's the reason why i need upload the picture to the post.

yet, it's important to me to get the correct frequency of cpu, and i can't explain it in english , sorry again.

On my Win11 VM on the last Proxmox 8 release it's as it it.

I don't care!
The real Intel Cor I5 cpu has 6 core with 12 threads, an the cpu clock jumps all the time.
That's ok for my.

When i run prime95 (linux) on the Proxmox VE debian 12 host, the speed settle for the first 56 seconds to the PL2, that i have set.
And drop then to the PL2 value, that my cpu cooler can handle for long time.

So i can check, if the system will work for me ok, over the test runtime of prime95.

there‘s no change when i try all of the cpu type in the vm device panel and install another os of it , so i'm sure this bug is somethings about PVE , maybe some lib Hiatus ，anyway。
andi find the same problem when i do some search in the forum ,here is

The virtual CPU frequency shown in a VM does not affect performance in any way. It is a fake number and doesn't mean anything. The host frequency is what matters.
