Hi,
A patchset about handling 'MCE' might have been ignored, can anyone tell
me whether the purpose is reasonable?

Although QEMU could catch signal BUS to handle hardware memory
corrupted event, sadly, QEMU just prints a little log and try to fix
it silently.
In these patches, introduce a 'MEMORY_FAILURE' event with 4 detailed
actions of QEMU, then uplayer could know what situaction QEMU hit and
did. And further step we can do: if a host server hits a 'hypervisor-ignore'
or 'guest-mce', scheduler could migrate VM to another host; if hitting
'hypervisor-stop' or 'guest-triple-fault', scheduler could select other
healthy servers to launch VM.
