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

I'll do so, but I can only make the conversion early mor

What probably was suggested is to disable cpu frequency
All,
I'm running a manually compiled KVM on CentOS 5.4. The KVM installation
has been carried over from CentOS 5.3, when KVM wasn't distributed with
the OS. (I tried to migrate to CentOS 5.4 native KVM support, but wasn't
able to get along with RedHat's interpretation of KVM.)
The KVM version use
