The cpuspeed packages provide a daemon to manage the CPU frequency scaling.

When the frequency scaling is enabled, a kernel panic can occur on a HMV (Hardware Virtual Machine) guest, and the following message is logged:
```
Kernel panic - not syncing: IO-APIC + timer doesn't work!
```
To work around this problem, change the default CPU governor to performance in the /etc/sysconfig/cpuspeed file as follows: GOVERNOR=performance.
