Description (last modified by )
MSR implementation under VirtualBox is quite usable, but the following MSRs are not provided if running on Haswell-ULT host CPU (e.g. CPU model number 0x45):
MSR_PKG_C8_RESIDENCY, MSR register 0x630 MSR_PKG_C9_RESIDENCY, MSR register 0x631 MSR_PKG_C10_RESIDENCY, MSR register 0x632
This may crash applications depending on these MSRs as they should be supported according to CPU model number. Currently PowerTOP is known to crash if running in guest using Haswell-ULT host CPU.
