      usb core: add migration support · c1ecb40a
      由 Gerd Hoffmann 提交于 
      Yes, seriously.  There is no migration support at all for usb devices.
They loose state, especially the device address, and stop responding
because of that.  Oops.

Luckily there is so much broken usb hardware out there that the guest
usually just kicks the device hard (via port reset and
reinitialization), then continues without a hitch.  So we got away with
that in a surprising high number of cases.

The arrival of remote wakeup (which enables autosuspend support) changes
that picture though.  The usb devices also forget that it they are
supposed to wakeup, so they don't do that.  The host also doesn't notice
the device stopped working in case it suspended the device and thus
expects it waking up instead of polling it.  Result is that your mouse
is dead.

Lets start fixing that.  Add a vmstate struct for USBDevice.

      spice: add qxl device · a19cbfb3
      由 Gerd Hoffmann 提交于 
      qxl is a paravirtual graphics card.  The qxl device is the bridge
between the guest and the spice server (aka libspice-server).  The
spice server will send the rendering commands to the spice client, which
will actually render them.

The spice server is also able to render locally, which is done in case
the guest wants read something from video memory.  Local rendering is
also used to support display over vnc and sdl.

qxl is activated using "-vga qxl".  qxl supports multihead, additional
cards can be added via '-device qxl".

[ v2: add copyright to files                     ]
[ v2: use qemu-common.h for standard includes    ]
[ v2: create separate qxl-vga device for primary ]

      vmstate: add subsections code · 811814bd
      由 Juan Quintela 提交于 
      This commit adds subsections for each device section.
Subsections is the way to handle information that don't need to be sent
to de destination of a migration because its values are not needed.  It is
the way to handle optional information.  Notice that only the source can
decide if the information is optional or not.  The destination needs to
understand all subsections that it receives to have a sucessful load.

      vmstate: Add support for alias ID · 4d2ffa08
      由 Jan Kiszka 提交于 
      Some legacy users (mostly PC devices) of vmstate_register manage
instance IDs on their own, and that unfortunately in a way that is
incompatible with automatically generated ones. This so far prevents
switching those users to vmstates that are registered by qdev.

To establish a migration path, this patch introduces the concept of
alias IDs. They can be passed to an extended vmstate registration
service, and qdev provides a set service to be used during device init.
find_se will consider the alias in addition to the default ID. We can
then start generating the default ID automatically and writing it on
vmsave, thus converting that format without breaking support for upward
migration.

The user is required specify the highest vmstate version for which the
alias is required. Once this version falls behind the minimum required
for a specific vmstate, an assertion triggers to motivate cleaning up
the obsolete alias.

      Block live migration · c163b5ca
      由 lirans@il.ibm.com 提交于 
      This patch introduces block migration called during live migration. Block
are being copied to the destination in an async way. First the code will
transfer the whole disk and then transfer all dirty blocks accumulted during
the migration.
Still need to improve transition from the iterative phase of migration to the
end phase. For now transition will take place when all blocks transfered once,
all the dirty blocks will be transfered during the end phase (guest is
suspended).

Changes from v4:
- Global variabels moved to a global state structure allocated dynamically.
- Minor coding style issues.
- Poll block.c for tracking of dirty blocks instead of manage it here.
