In addition, we can compare /sys/kernel/debug/kvm/largepages w/ and
w/o the patch. IIRC, /sys/kernel/debug/kvm/largepages will drop during
live migration, it will keep a small value if live migration fails and
w/o "lazy collapse small sptes into large sptes" codes, however, it
will increase gradually if w/ the "lazy collapse small sptes into
large sptes" codes.

we do not even emulate IIRC). In that case, the OS is under risk of
sleeping forever, thus need to look for a different wakeup source.
HPET will always be the default broadcast event device I think.

This series aggressively refactors the PC machine initialization to be more
modelled and less ad-hoc. The highlights of this series are:
1) Things like -m and -bios-name are now device model properties
2) The i440fx and piix3 are now modelled in a thorough fashion
3) i440fx_init is trivialized
