      spice: turn client_migrate_info to async · edc5cb1a
      由 Yonit Halperin 提交于 
      RHBZ 737921
Spice client is required to connect to the migration target before/as migration
starts. Since after migration starts, the target qemu is blocked and cannot accept new spice client
we trigger the connection to the target upon client_migrate_info command.
client_migrate_info completion cb will be called after spice client has been
connected to the target (or a timeout). See following patches and spice patches.

      Introduce a 'client_add' monitor command accepting an open FD · 13661089
      由 Daniel P. Berrange 提交于 
      Allow client connections for VNC and socket based character
devices to be passed in over the monitor using SCM_RIGHTS.

One intended usage scenario is to start QEMU with VNC on a
UNIX domain socket. An unprivileged user which cannot access
the UNIX domain socket, can then connect to QEMU's VNC server
by passing an open FD to libvirt, which passes it onto QEMU.

 { "execute": "get_fd", "arguments": { "fdname": "myclient" } }
 { "return": {} }
 { "execute": "add_client", "arguments": { "protocol": "vnc",
                                           "fdname": "myclient",
                                           "skipauth": true } }
 { "return": {} }

In this case 'protocol' can be 'vnc' or 'spice', or the name
of a character device (eg from -chardev id=XXXX)

The 'skipauth' parameter can be used to skip any configured
VNC authentication scheme, which is useful if the mgmt layer
talking to the monitor has already authenticated the client
in another way.

* console.h: Define 'vnc_display_add_client' method
* monitor.c: Implement 'client_add' command
* qemu-char.c, qemu-char.h: Add 'qemu_char_add_client' method
* qerror.c, qerror.h: Add QERR_ADD_CLIENT_FAILED
* qmp-commands.hx: Declare 'client_add' command
* ui/vnc.c: Implement 'vnc_display_add_client' method

      block QMP: Deprecate query-block's "type", drop info block's "type=" · d8aeeb31
      由 Markus Armbruster 提交于 
      query-block's specification documents response member "type" with
values "hd", "cdrom", "floppy", "unknown".

Its value is unreliable: a block device used as floppy has type
"floppy" if created with if=floppy, but type "hd" if created with
if=none.

That's because with if=none, the type is at best a declaration of
intent: the drive can be connected to any guest device.  Its type is
really the guest device's business.  Reporting it here is wrong.

No known user of QMP uses "type".  It's unlikely that any unknown
users exist, because its value is useless unless you know how the
block device was created.  But then you also know the true value.

Fixing the broken value risks breaking (hypothetical!) clients that
somehow rely on the current behavior.  Not fixing the value risks
breaking (hypothetical!) clients that rely on the value to be
accurate.  Can't entirely avoid hypothetical lossage.  Change the
value to be always "unknown".

This makes "info block" always report "type=unknown".  Pointless.
Change it to not report the type.

      block: add block_resize monitor command · 6d4a2b3a
      由 Christoph Hellwig 提交于 
      Add a monitor command that allows resizing of block devices while
qemu is running.  It uses the existing bdrv_truncate method already
used by qemu-img to do it's work.  Compared to qemu-img the size
parsing is very simplicistic, but I think having a properly numering
object is more useful for non-humand monitor users than having
the units and relative resize parsing.

For SCSI devices the new size can be updated in Linux guests by
doing the following shell command:

	echo > /sys/class/scsi_device/0:0:0:0/device/rescan

For ATA devices I don't know of a way to update the block device
size in Linux system, and for virtio-blk the next two patches
will provide an automatic update of the size when this command
is issued on the host.

      spice/vnc: client migration. · e866e239
      由 Gerd Hoffmann 提交于 
      Handle spice client migration, i.e. inform a spice client connected
about the new host and connection parameters, so it can move over the
connection automatically.

The monitor command has a not-yet used protocol argument simliar to
set_password and expire_password commands.  This allows to add a simliar
feature to vnc in the future.  Daniel Berrange plans to work on this.
