block/mirror: change the semantic of 'force' of block-job-cancel
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.

block/snapshot.c: eliminate use of ID input in snapshot operations
At this moment, QEMU attempts to create/load/delete snapshots
by using either an ID (id_str) or a name. The problem is that the code
isn't consistent of whether the entered argument is an ID or a name,
causing unexpected behaviors.
For example, when creating snapshots via savevm <arg>, what happens is that
"arg" is treated as both name and id_str. In a guest without snapshots, create
a single snapshot via savevm:
(qemu) savevm 0
(qemu) info snapshots
List of snapshots present on all disks:
ID TAG VM SIZE DATE VM CLOCK
-- 0 741M 2018-07-31 13:39:56 00:41:25.313
A snapshot with name "0" is created. ID is hidden from the user, but the
ID is a non-zero integer that starts at "1". Thus, this snapshot has
id_str=1, TAG="0". Creating a second snapshot with arg = 1, the first one
is deleted:
(qemu) savevm 1
(qemu) info snapshots
List of snapshots present on all disks:
ID TAG VM SIZE DATE VM CLOCK
-- 1 741M 2018-07-31 13:42:14 00:41:55.252
What happened?
- when creating the second snapshot, a verification is done inside
bdrv_all_delete_snapshot to delete any existing snapshots that matches an
string argument. Here, the code calls bdrv_all_delete_snapshot("1", ...);
- bdrv_all_delete_snapshot calls bdrv_snapshot_find(..., "1") for each
BlockDriverState of the guest. And this is where things goes tilting:
bdrv_snapshot_find does a search by both id_str and name. It finds
out that there is a snapshot that has id_str = 1, stores a reference
to the snapshot in the sn_info pointer and then returns match found;
- since a match was found, a call to bdrv_snapshot_delete_by_id_or_name() is
made. This function ignores the pointer written by bdrv_snapshot_find. Instead,
it deletes the snapshot using bdrv_snapshot_delete() calling it first with
id_str = 1. If it fails to delete, then it calls it again with name = 1.
- after all that, QEMU creates the new snapshot, that has id_str = 1 and
name = 1. The user is left wondering that happened with the first snapshot
created. Similar bugs can be triggered when using loadvm and delvm.
Before contemplating discarding the use of ID input in these operations,
I've searched the code of what would be the implications. My findings
are:
- the RBD and Sheepdog drivers don't care. Both uses the 'name' field as
key in their logic, making id_str = name when appropriate.
replay-snapshot.c does not make any special use of id_str;
- qcow2 uses id_str as an unique identifier but it is automatically
calculated, not being influenced by user input. Other than that, there are
no distinguish operations made only with id_str;
- in blockdev.c, the delete operation uses a match of both id_str AND
name. Given that id_str is either a copy of 'name' or auto-generated,
we're fine here.
This gives motivation to not consider ID as a valid user input in HMP
commands - sticking with 'name' input only is more consistent. To
accomplish that, the following changes were made in this patch:
- bdrv_snapshot_find() does not match for id_str anymore, only 'name'. The
function is called in save_snapshot(), load_snapshot(), bdrv_all_delete_snapshot()
and bdrv_all_find_snapshot(). This change makes the search function more
predictable and does not change the behavior of any underlying code that uses
these affected functions, which are related to HMP (which is fine) and the
main loop inside vl.c (which doesn't care about it anyways);
- bdrv_all_delete_snapshot() does not call bdrv_snapshot_delete_by_id_or_name
anymore. Instead, it uses the pointer returned by bdrv_snapshot_find to
erase the snapshot with the exact match of id_str an name. This function
is called in save_snapshot and hmp_delvm, thus this change produces the
intended effect;
- documentation changes to reflect the new behavior. I consider this to
be an API fix instead of an API change - the user was already creating
snapshots using 'name', but now he/she will also enjoy a consistent
behavior.
Ideally we would get rid of the id_str field entirely, but this would have
repercussions on existing snapshots. Another day perhaps.

``xp /``\ *fmt* *addr*
|
|
|
|
Physical memory dump starting at *addr*.
|
|
|
|
|
|
|
|
*fmt* is a format which tells the command how to format the
|
|
|
|
data. Its syntax is: ``/{count}{format}{size}``
|
|
|
|
|
|
|
|
*count*
|
|
|
|
is the number of items to be dumped.
|
|
|
|
*format*
|
|
|
|
can be x (hex), d (signed decimal), u (unsigned decimal), o (octal),
|
|
|
|
c (char) or i (asm instruction).
|
|
|
|
*size*
|
|
|
|
can be b (8 bits), h (16 bits), w (32 bits) or g (64 bits). On x86,
|
|
|
|
``h`` or ``w`` can be specified with the ``i`` format to
|
|
|
|
respectively select 16 or 32 bit code instruction size.
|
|
|
|
|
|
|
|
Examples:
|
|
|
|
|
|
|
|
Dump 10 instructions at the current instruction pointer::
|
|
|
|
|
|
|
|
(qemu) x/10i $eip

qemu-char: Saner naming of memchar stuff & doc fixes
New device, has never been released, so we can still improve things
without worrying about compatibility.
Naming is a mess. The code calls the device driver CirMemCharDriver,
the public API calls it "memory", "memchardev", or "memchar", and the
special commands are named like "memchar-FOO". "memory" is a
particularly unfortunate choice, because there's another character
device driver called MemoryDriver. Moreover, the device's distinctive
property is that it's a ring buffer, not that's in memory. Therefore:
* Rename CirMemCharDriver to RingBufCharDriver, and call the thing a
"ringbuf" in the API.
* Rename QMP and HMP commands from memchar-FOO to ringbuf-FOO.
* Rename device parameter from maxcapacity to size (simple words are
good for you).
* Clearly mark the parameter as optional in documentation.
* Fix error reporting so that chardev-add reports to current monitor,
not stderr.
* Replace cirmem in C identifiers by ringbuf.
* Rework documentation. Document the impact of our crappy UTF-8
handling on reading.
* QMP examples that even work.
I could split this up into multiple commits, but they'd change the
same documentation lines multiple times. Not worth it.

|
|
Trigger a round of GARP/RARP broadcasts; this is useful for explicitly
|
|
|
|
updating the network infrastructure after a reconfiguration or some forms
|
|
|
|
of migration. The timings of the round are set by the migration announce
|
|
|
|
parameters. An optional comma separated *interfaces* list restricts the
|
|
|
|
announce to the named set of interfaces. An optional *id* can be used to
|
|
|
|
start a separate announce timer and to change the parameters of it later.

COLO: Add 'x-colo-lost-heartbeat' command to trigger failover
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.

Set replay breakpoint at instruction count *icount*.

Execution stops when the specified instruction is reached.
|

|
There can be at most one breakpoint. When breakpoint is set, any prior
|
|
|
|
one is removed. The breakpoint may be set only in replay mode and only
|
|
|
|
"in the future", i.e. at instruction counts greater than the current one.
|
|
|
|
The current instruction count can be observed with ``info replay``.

Automatically proceed to the instruction count *icount*, when

replaying the execution. The command automatically loads nearest

|
|
|
snapshot and replays the execution to find the desired instruction.
|

When there is no preceding snapshot or the execution is not replayed,
