I'd like to ask, are there any recommendation about kernel timer frequency

I guess that on host, the higher frequency can be better, but for guest,
100HZ should be better because it causes lower overhead for host, right?

The current way of injecting MCE events without updating of and
synchronizing with the CPUState is broken and causes spurious
corruptions of the MCE-related parts of the CPUState.
As a first step towards a fix, enhance the state writeback code with
support for injecting events that are pending in
MCEs can be injected asynchronously, so they can also terminate the halt
