VIR_DOMAIN_EVENT_SUSPENDED_POSTCOPY and VIR_DOMAIN_PAUSED_POSTCOPY are
used on the source host once migration enters post-copy mode (which
means the domain gets paused on the source. After the destination host
takes over the execution of the domain, its virtual CPUs are resumed and
the domain enters VIR_DOMAIN_RUNNING_POSTCOPY state and
VIR_DOMAIN_EVENT_RESUMED_POSTCOPY event is emitted.
In case migration fails during post-copy mode and none of the hosts have
complete state of the domain, both domains will remain paused with
VIR_DOMAIN_PAUSED_POSTCOPY_FAILED reason and an upper layer may decide
what to do.

Some hypervisors (namely qemu) can have a separate connecton for
non-shared disks migration of active domains. Currently we have
no means to control the port of such a connection. At the same
time we have options to control port of memory migration traffic
(thru migration uri) as well as interfaces that target server
is bound to for incoming migration (thru VIR_MIGRATE_PARAM_LISTEN_ADDRESS).
Let's add the option for setting disks port too.

The API docs state that the API queries pinning info for all vCPUs and
thus we should allocate the bitmap even for the inactive ones.
The API will currently return bitmap only for the active vCPUs but that
will change in the future.
The VIR_DOMAIN_EVENT_ID_JOB_COMPLETED event will be triggered once a job
(such as migration) finishes and it will contain statistics for the job
as one would get by calling virDomainGetJobStats. Thanks to this event
it is now possible to get statistics of a completed migration of a
transient domain on the source host.

Since we have the macro there's no need for us to unwind it by
hand and check for mutually exclusive flags ourselves.
Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
Rather than setting flags to -1 if none were specified, move the logic
to use the old API to the place where we need to decide. It simplifies
the logic a bit.
Since the code is changing the source image path by modifying the
existing XML snippet the <backingStore> stays in place.
As <backingStore> is relevant to the <source> part of the image, the
update of that part makes the element invalid.
CD/floppy images usually don't have a backing chain and the element is
currently ignored though but it might start being used in the future so
let's start behaving correctly.
Drop the <backingStore> subtree once we want to update the XML.
Before this patch, you'd get:
$ virsh change-media --eject --print-xml 10 hdc
<disk type="file" device="cdrom">
<driver name="qemu" type="qcow2"/>
<backingStore type="file" index="1">
<format type="qcow2"/>
<source file="/var/lib/libvirt/images/vm.1436949097"/>
<backingStore/>
</backingStore>
<target dev="hdc" bus="ide"/>
...
</disk>
After:
$ virsh change-media --eject --print-xml 10 hdc
<disk type="file" device="cdrom">
<driver name="qemu" type="qcow2"/>
<target dev="hdc" bus="ide"/>
...
</disk>
The macro would eat the first parameter. In some cases the format string
for vshPrint was eaten. In other cases the calls referenced variables
which did not exist in the given context. Avoid errors by doing compile
time checking.
After a block job hits 100%, we only need to apply a timeout waiting for
a block job event if exactly one of the BLOCK_JOB or BLOCK_JOB_2
callbacks were able to be registered.
If neither callback could be registered, there's clearly no need for a
timeout.
If both callbacks were registered, then we're guaranteed to eventually
get one of the events. The path being used by virsh must be exactly the
source path or target device in the domain's disk definition, and these
are the respective strings sent back in these two events.

It all works like this. The change-media command dumps domain
XML, finds the corresponding cdrom device we want to change media
in and returns it in the xmlNodePtr form. This way we don't have
to bother with keeping all the subelements or attributes that we
don't care about in the XML that is fed back to libvirt for the
update API.
Now, the problem is we try to be clever here and detect if disk
already has a source (indicated by <source/> subelement).
However, bare fact that the element is there does not mean disk
has source. Make our clever check better.

Commit id '3c7590e0a' added the flag to the rbd backend, but provided
no means via virsh to use the flag. This patch adds a '--delete-snapshots'
option to both the "undefine" and "vol-delete" commands.
For "undefine", the flag is combined with the "--remove-all-storage" flag
in order to add the appropriate flag for the virStorageVolDelete call;
whereas, for the "vol-delete" command, just the flag is sufficient since
it's only operating on one volume.
Currently only supported for rbd backends.

QEMU call:
-net socket,udp=127.0.0.1:11112,localaddr=127.0.0.1:22222
Notice the xml "local" entry becomes the "localaddr" for the qemu call.

When looking up a domain, we try to look up by ID, UUID and NAME
consequently while not really caring which of those lookups succeeds.
The problem is that if any of them fails, we dispatch the error from the
driver and that means setting both threadlocal and global error. Let's
say the last lookup (by NAME) succeeds and resets the threadlocal error as any
other API does, however leaving the global error unchanged. If the underlying
virsh command does not succeed afterwards, our cleanup routine in
vshCommandRun ensures that no libvirt error will be forgotten and that's
exactly where this global error comes in incorrectly.
# virsh domif-setlink 123 vnet1 up
error: interface (target: vnet1) not found
error: Domain not found: no domain with matching id 123

In order to share as much virsh' logic as possible with upcomming
virt-admin client we need to split virsh logic into virsh specific and
client generic features.
Since majority of virsh methods should be generic enough to be used by
other clients, it's much easier to rename virsh specific data to virshX
than doing this vice versa. It moved generic virsh commands (including info
and opts structures) to generic module vsh.c.
Besides renaming methods and structures, this patch also involves introduction
of a client specific control structure being referenced as private data in the
original control structure, introduction of a new global vsh Initializer,
which currently doesn't do much, but there is a potential for added
functionality in the future.
Lastly it introduced client hooks which are especially necessary during
client connecting phase.
This patch implements new virsh command, domrename.
Using domrename, it will be possible to rename domain from the virsh shell by
calling virRenameDomain API.
It takes two arguments, current domain name and new domain name.

virsh # list --all
Id Name State
----------------------------------------------------
- bar shut off
virsh # domrename bar foo
Domain successfully renamed
virsh # list --all

Reuse the vshBlockJobWait infrastructure to refactor cmdBlockCommit to
use the common code. This additionally fixes a bug when working with
new qemus, where when doing an active commit with --pivot the pivoting
would fail, since qemu reaches 100% completion but the job doesn't
switch to synchronized phase right away.
Introduce helper function that will provide logic for waiting for block
job completion so the 3 open coded places can be unified and improved.
This patch introduces the whole logic and uses it to fix
cmdBlockJobPull. The vshBlockJobWait function provides common logic for
block job waiting that should be robust enough to work across all
previous versions of libvirt. Since virsh allows passing user-provided
strings as paths of block devices we can't reliably use block job events
for detection of block job states so the function contains a great deal
of fallback logic.
Use the VSH_EXCLUSIVE_OPTIONS to exclude combinations of --pivot and
--keep-overlay and refactor the enforcing of the --wait option and other
flags that imply --wait.
Use the VSH_EXCLUSIVE_OPTIONS_VAR to interlock incompatible options.
Since a variable named 'abort' would conflict with older compilers use
VSH_EXCLUSIVE_OPTIONS for the --abort option.
There's this condition:
flags & VIR_DOMAIN_AFFECT_CURRENT && virDomainIsActive(dom)
which can never be true since VIR_DOMAIN_AFFECT_CURRENT has hardcoded
value of zero. Therefore virDomainIsActive() is a dead code. However,

When watching a job (save, managedsave, dump, migrate) virsh spawns a
thread to call the appropriate API and waits for the result while
watching for interruption signals (SIGINT, Ctrl-C on the terminal).
Whenever such signal is caught, virsh calls virDomainAbortJob, stops
waiting for the job, and returns the result of virDomainAbortJob.
This is wrong because the job might have finished in the meantime or it
might have been cancelled by someone else and virsh would just report
the failure to abort the job. However, we are not interested in the
virDomainAbortJob's result at all, we need to keep waiting for the main
job to finish and report its result instead.

Commit a0670ae caused a regression in 'virsh event' and
'virsh qemu-monitor-event' - if a user tries to filter the
command to a specific domain, an error message is printed:
$ virsh event dom --loop
error: internal error: virsh qemu-monitor-event: no domain VSH_OT_DATA option
and then the command continues as though no domain had been
supplied (giving events for ALL domains, instead of the
requested one). This is because the code was incorrectly
assuming that all "domain" options would be supplied via a
mandatory VSH_OT_DATA, even though "domain" is optional for
these two commands, so we had changed them to VSH_OT_STRING
to quit failing for other reasons (ever since it was decided
that VSH_OT_DATA and VSH_OT_STRING should no longer be
synonyms).
In looking at the situation, though, the code for looking up
a domain was making a pointless check for whether the option
exists prior to finding the option's string value, as
vshCommandOptStringReq does just fine at reporting any errors
when looking up a string whether or not the option was present.
So this is a case of regression fixing by pure code deletion :)

When set guest memory with a invalid parameter of --soft-limit,
it posts weird error:
$ virsh memtune r7 --hard-limit 20417224 --soft-limit 9007199254740992 \
--swap-hard-limit 35417224
error: Unable to parse integer parameter 'NAME
Change it to
error: Unable to parse integer parameter soft-limit

Use virBitmapDataToString instead of constructing the ranges bit
by bit, remove the checking of parameters (that is already done
by the callers).
Let the callers choose the right bitmap, since there's only
one that uses this helper on a matrix-in-an-array.
$ sudo virsh change-media f19 hdc /mnt/data/devel/media/Fedora-16-x86_64-Live-KDE.iso
succeeded to complete action update on media
Change the message to:
Successfully {inserted,ejected,changed} media.

The overflow check for the bandwidth parameter did not jump to the
cleanup label.
Additionally virsh should use vshError instead of virReportError.
