7	<p>Some legacy Linux guests may cause a high CPU load even if the guest system appears to be idle. This can be caused by a high timer frequency of the guest kernel. Some older Linux distributions ship a Linux kernel configured for a timer frequency of 1000Hz. We recommend recompiling the guest kernel and selecting a timer frequency of 100Hz.</p>
8	<p>Linux kernels shipped with Red Hat Enterprise Linux, as well as kernels of related Linux distributions, such as CentOS and Oracle Linux, support a kernel parameter <i>divider=N</i>. Hence, such kernels support a lower timer frequency without recompilation. Add the kernel parameter <i>divider=10</i> to select a guest kernel timer frequency of 100Hz.</p>
