When doing drive mirror to a low speed shared storage, if there was heavy
BLK IO write workload in VM after the 'ready' event, drive mirror block job
can't be canceled immediately, it would keep running until the heavy BLK IO
workload stopped in the VM.
Libvirt depends on the current block-job-cancel semantics, which is that
when used without a flag after the 'ready' event, the command blocks
until data is in sync. However, these semantics are awkward in other
situations, for example, people may use drive mirror for realtime
backups while still wanting to use block live migration. Libvirt cannot
start a block live migration while another drive mirror is in progress,
but the user would rather abandon the backup attempt as broken and
proceed with the live migration than be stuck waiting for the current
drive mirror backup to finish.
The drive-mirror command already includes a 'force' flag, which libvirt
does not use, although it documented the flag as only being useful to
quit a job which is paused. However, since quitting a paused job has
the same effect as abandoning a backup in a non-paused job (namely, the
destination file is not in sync, and the command completes immediately),
we can just improve the documentation to make the force flag obviously
useful.

QEMU's screendump command can only take dumps from the primary display.
When using multiple VGA cards, there is no way to get a dump from a
secondary card or other display heads yet. So let's add a 'device' and
a 'head' parameter to the HMP and QMP commands to be able to specify
alternative devices and heads with the screendump command, too.

They are deprecated since QEMU v2.10, and so far nobody complained that
these commands are still necessary for any reason - and since you can use
'netdev_add' and 'netdev_remove' instead, there also should not be any
real reason. Since they are also standing in the way for the upcoming
'vlan' clean-up, it's now time to remove them.

It does not make much sense to limit these commands to the legacy 'vlan'
concept only, they should work with the modern netdevs, too. So now
it is possible to use this command with one, two or three parameters.
With one parameter, the command installs a hostfwd rule on the default
"user" network:
hostfwd_add tcp:...
With two parameters, the command installs a hostfwd rule on a netdev
(that's the new way of using this command):
hostfwd_add netdev_id tcp:...
With three parameters, the command installs a rule on a 'vlan' (aka hub):
hostfwd_add hub_id name tcp:...
Same applies to the hostfwd_remove command now.

there is no need for any explicit encryption handling APIs

within the block driver. We only retain an API for querying

We leave users to choose whatever heartbeat solution they want,
if the heartbeat is lost, or other errors they detect, they can use
experimental command 'x_colo_lost_heartbeat' to tell COLO to do failover,
COLO will do operations accordingly.
For example, if the command is sent to the Primary side,
the Primary side will exit COLO mode, does cleanup work,
and then, PVM will take over the service work. If sent to the Secondary side,
the Secondary side will run failover work, then takes over PVM's service work.

The idea is simple - backup is "written-once" data. It is written block
by block and it is large enough. It would be nice to save storage
space and compress it.
The patch adds a flag to the qmp/hmp drive-backup command which enables
block compression. Compression should be implemented in the format driver
to enable this feature.
There are some limitations of the format driver to allow compressed writes.
We can write data only once. Though for backup this is perfectly fine.
These limitations are maintained by the driver and the error will be
reported if we are doing something wrong.

Define two new migration parameters to be used with TLS encryption.
The 'tls-creds' parameter provides the ID of an instance of the
'tls-creds' object type, or rather a subclass such as 'tls-creds-x509'.
Providing these credentials will enable use of TLS on the migration
data stream.
If using x509 certificates, together with a migration URI that does
not include a hostname, the 'tls-hostname' parameter provides the
hostname to use when verifying the server's x509 certificate. This
allows TLS to be used in combination with fd: and exec: protocols
where a TCP connection is established by a 3rd party outside of
QEMU.
NB, this requires changing the migrate_set_parameter method in the
HMP to accept a 's' (string) value instead of 'i' (integer). This
is backwards compatible, because the parsing of strings allows the
quotes to be optional, thus any integer is also a valid string.

This patch adds an option to the drive_add HMP command to create only a
BlockDriverState without a BlockBackend on top.
The motivation for this is that libvirt needs to specify options to a
migration target (specifically, detect-zeroes). drive-mirror doesn't
allow specifying options, and the proper way to do this is to create the
target BDS separately with blockdev-add (where you can specify options)
and then use blockdev-mirror to that BDS.
However, libvirt can't use blockdev-add as long as it is still
experimental, and we're expecting that it will still take some time, so
we need to resort to drive_add.
The problem with drive_add is that so far it always created a BB, and
BDSes with a BB can't be used as a mirroring target as long as we don't
support multiple BBs per BDS - and while we're working towards that
goal, it's another thing that will still take some time.
So to achieve the goal, the simplest solution to provide the
functionality now without adding one-off options to the mirror QMP
commands is to extend drive_add to create nodes without BBs.

device short ID. device_add allows devices to be created
without giving an ID, at which point there is no way to
delete them with device_del. The QOM object path, however,
provides an alternative way to identify the devices.
Allowing device_del to accept an object path ensures all

All QMP commands use the "new" handler interface (mhandler.cmd_new).
Most HMP commands still use the traditional interface (mhandler.cmd),
but a few use the "new" one. Complicates handle_user_command() for no
gain, so I'm converting these to the traditional interface.
pcie_aer_inject_error's implementation is split into the
hmp_pcie_aer_inject_error() and pcie_aer_inject_error_print(). The
former is a peculiar crossbreed between HMP and QMP handler. On
success, it works like a QMP handler: store QDict through ret_data
parameter, return 0. Printing the QDict is left to
pcie_aer_inject_error_print(). On failure, it works more like an HMP
handler: print error to monitor, return negative number.
To convert to the traditional interface, turn
pcie_aer_inject_error_print() into a command handler wrapping around
hmp_pcie_aer_inject_error(). By convention, this command handler
should be called hmp_pcie_aer_inject_error(), so rename the existing
hmp_pcie_aer_inject_error() to do_pcie_aer_inject_error().

For device_add, that's easy: just wrap the obvious hmp_device_add()
around do_device_add().
monitor_user_noop() is now unused, drop it.

Protocol must be spice, vnc isn't implemented. Fix up documentation.
Attempts to use vnc or any other unknown protocol yield the misleading
error message "Invalid parameter 'protocol'". Improve it to
"Parameter 'protocol' expects spice".

Live migration with spice works like this today:
(1) client_migrate_info monitor cmd
(2) spice server notifies client, client connects to target host.
(3) qemu waits until spice client connect is finished.
(4) send over vmstate (i.e. main part of live migration).
(5) spice handover to target host.
(3) is implemented by making client_migrate_info a async monitor
command. This is the only async monitor command we have.
The original reason to implement this dance was that qemu did not accept
new tcp connections while the incoming migration was running, so (2) and
(4) could not be done in parallel. That issue was fixed long ago though.
Qemu version 1.3.0 (released Dec 2012) and newer happily accept tcp
connects while the incoming migration runs.
Time to drop step (3). This patch does exactly that, by making the
monitor command synchronous and removing the code needed to handle the
async monitor command in ui/spice-core.c

Several issues:
* Commands i and o lack @item. Their one-liner documentation gets
squashed into the preceding command print. Add the obvious @item.
* Commands i, o and cpu-add lack @findex. The function index doesn't
have them. Add the obvious @findex.
* Commit 727f005 put block_set_io_throttle was added in the middle of
block_passwd. Move it.
* Correct spelling of commands chardev-add and chardev-remove in @item
and @findex.
* Some commands have a blank line between @item/@findex and the text,
most don't. Normalize to no blank line.

The command handler is a union of two function types. If
cmd->user_print is set, handle_user_command() calls
cmd->mhandler.cmd_new(), else cmd->mhandler.cmd().
Command definitions must therefore either set both user_print() and
mhandler.cmd_new(), or only mhandler.cmd().
quit's sets user_print and mhandler.cmd(). handle_user_command()
calls hmp_quit() through mhandler.cmd_new() rather than
mhandler.cmd(), i.e. through a function pointer with a different type.
Broken in commit 7a7f325, v1.0.
Works in practice because hmp_quit() doesn't use its arguments, and
handle_user_command() ignores its function value.

To complement qdev's bus-oriented info qtree, info qom-tree
prints a hierarchical view of the QOM composition tree.
By default, the machine composition tree is shown. This can be overriden
by supplying a path argument, such as "info qom-tree /".
