cpu frequency

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

A commercial application running on Windows (kvm guest) detects CPU as:
CPU_0: CPU0, Intel64 Family 6 Model 42 Stepping 1, 64, 64, 2200,
078BFBFD000206A1, 10753, CPU 0
After some time, without reboot, it detects as:
CPU_0: CPU0, Intel64 Family 6 Model 42 Stepping 1, 64, 64, 2298,
078BFBFD000206A1, 10753, CPU 0

Windows Server 2012 Control Panel -> System shows CPU as 2.3 GHZ, but after 
reboot it might show 2.2 or 1.97 GHz.

The problem is, that commercial application stops working after it detects 
CPU frequency change (2200 -> 2298 in above case). Is it possible to patch 
qemu-kvm that it shows some constant frquency to the guest?

Regards,
Nerijus
