My resource:
kernel: 4.16.8
host system: Ubuntu 16.04
Llbvirt : 4.2
Qemu : 2.12
Cpu : intel@core i7 6700
guest system: windows7 professional
My problem:
In my host, Cpu frequency is 3800~3900 MHz(4 socket and 2 thread) because i turn on ˇ°Intel Turbo Boostˇ±. And silent frequency is 3.40 GHz.
Then i boot my guest, But in Guest my cpu frequency is 3408 MHz. why it's not 3800 MHz?
And here is my guest xml:
<cpu mode='host-passthrough' check='none'>
<topology sockets='1' cores='8' threads='1'/>
</cpu>
