14099	MSR_PKG_C[8-10]_RESIDENCY are not provided with Haswell-ULT host CPU	yarda		"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.
