The CloudStack agents will attempt to +get the CPU speed by reading the `/sys/devices/system/cpu/cpu0/cpufreq/base_frequency` information. +However, the CPU speed information is not included in all the CPU architectures. Review Comment: ```suggestion However, the CPU speed information is not included in all the CPU architectures. In such cases, `libvirt` is used to retrieve the CPU speed which may not always report the correct base speed value for the CPU. ``` ########## source/upgrading/upgrade/kvm-417.rst: ########## @@ -0,0 +1,30 @@ +..
