Change -numa option like following as Paolo suggested:
-numa node,nodeid=0,cpus=0-1 \
-numa mem,nodeid=0,size=1G
This new option will make later coming memory hotplug better.
And this new option is implemented using OptsVisitor.
And just remain "-numa node,mem=xx" as legacy.

If the total number of the assigned numa nodes memory is not
equal to the assigned ram size, it will write the wrong data

Convert mainloop to use timeout from default timerlist group
(i.e. the current 3 static timers)
main-loop.c produces a (possibly spurious) warning about
multiple iterations. Adapt the way this works for a signed
timeout and make the warning a bit safer.

Add a QEMUTimerListGroup each AioContext (meaning a QEMUTimerList
associated with each clock is added) and delete it when the
AioContext is freed.

include/qemu/timer.h has no need to include main-loop.h and
doing so causes an issue for the next patch. Unfortunately
various files assume including timers.h will pull in main-loop.h.
Untangle this mess.

Add QEMUTimerListGroup and helper functions, to represent
a QEMUTimerList associated with each clock. Add a default
QEMUTimerListGroup representing the default timer lists
which are not associated with any other object (e.g.
an AioContext as added by future patches).

Calculate the timeout in aio_ctx_prepare taking into account
the timers attached to the AioContext.
Alter aio_ctx_check similarly.

When user tries to use read-only whitelist format in the command line
option, failure message was "'foo' invalid format". It might be invalid
only for writable, but valid for read-only, so it is confusing. Give the
user easier to understand information.

Split QEMUClock into QEMUClock and QEMUTimerList so that we can
have more than one QEMUTimerList associated with the same clock.
Introduce a main_loop_timerlist concept and make existing
qemu_clock_* calls that actually should operate on a QEMUTimerList

VMDK3 header has the field l1dir_size, but vmdk_open_vmdk3 hardcoded the
value. This patch honors the header field.
And the L2 table size is 4096 according to VMDK spec[1], instead of
1 << 9 (512).

While Asias is debugging an issue creating qcow2 images on top of
non-file protocols. It boils down to this example using NBD:

VMware ESX hosts also use different create and extent types for flat
files, respectively "vmfs" and "VMFS". This is not documented, but it
can be found at http://kb.vmware.com/kb/10002511 (Recreating a missing
virtual machine disk (VMDK) descriptor file).
