Hi Les, Everything under http://people.centos.org/tru/ is signed for testing and feedback before it can be built by the CentOS build systems and enter either the regular testing repository or their final destination.

Thanks Tru and Johnny, one more question. Can I just use the centos5-testing repo, ie, yum enablerepoxxx install kernel-vm? I ask because I tried and while it worked it loaded an older kernel. Should I just go to tru's directory and install the RPM directly? Also, ok more than one question, are the open-vm-tools in the same repo or only found in Johnny's testing directory. Thanks again...

The CentOS bug entry referred to by the original poster explains in great details why a kernel with 100hz clock rate (kernel-vm) gives you improved performance compared to the distro standard kernel (1000hz) and handles clock drifts better. Recent distro kernels offer a new kernel option divider= that lets you reduce the clock rate. This should eventually eliminate the need for the kernel-vm. However, at the moment, the divider= option has a bug that causes problems when it is combined with clocksource=pit. And the timer pit is often used when the system clock tends to go faster.

Thanks much, I have in the past compiled my own but thought I would check. A big THANKS to whoever provides them...
