Hello all: I am trying to follow the RHEL virtualization guide. According to Chapter 17, I have a processor without a constant Time Stamp Counter (Its an Opteron). According to that guide, I need to set the MIN_SPEED and MAX_SPEED variables in /etc/sysconfig/cpuspeed to the highest frequency show in /sys/devices/system/cpu/cpu*/cpufreq/scaling_available_frequencies I took a look at my system (CentOS 5.4) and there are no cpufreq directories in the cpu folders. Is that a problem?
