Top-post due to prior: VMWare Server 1.x/ Win2K3 server, standalone and as host for above. VMWare ESXi: Win2K3 and Win2K systems trash volumes. Basically the CPU scaling on the host makes the guest OS fall apart.

Xen handles the AMD HE CPUs just fine here. What sort of breakage are you experiencing?

Hi, could anyone here have some idea of the following questions about Dynamic Voltage/Frequency Scaling techniques used for energy efficiency, or please give a pointer that I can trace, 1) how many servers in the market support this technique? 2) how many voltages/frequencies can the servers support? 3) What's the transition time and cost (power) between these voltages/frequencies?
Thanks, -Kai _______________________________________________________________________ _ ____________________________________
My experience with the AMD HE CPUs has been that the scaling breaks Win2K3, and any virtualized environments.
