You had only one job. That's what you can say about this example
binary. In future, parts of virsh that are usable for this binary
should be split into separate shell-utils and virt-admin should gain all
the cool features of virsh without too much code addition.

In the pre-NUMA ages pinning a vCPU to all pCPUs was eaqual to deleting
the pinning info. Now it does not entirely work that way. Pinning a vCPU
to all pCPUs might be a desired operation. Additionally removal of the
pinning will result into using the default pinning information at the
next boot which might be different from all vcpus.
This patch removes the false assumption that we should remove the
pinning after pinning to all vCPUs and tweaks the documentation for
virsh.
A later patch will implement a new flag for the virDomainPinVcpuFlags
API that will allow to remove the pinning in a sane way.
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.

This will allow us to use vshError() to report errors from inside
vshCommandOpt*(), instead of replicating the same logic and error
messages all over the place.
We also have more context inside the vshCommandOpt*() functions,
for example the actual value used on the command line, which means
we can produce more detailed error messages.
vshCommandOptBool() is the exception here, because it's explicitly
designed not to report any error.
When shrinking a volume by a certain size, instead of typing
vol-resize volume 1G --delta --shrink
we allow the convience of specifying a negative value:
vol-resize volume -1G --delta --shrink
getting the same results with one more character.
A negative value only makes sense as a delta. Imply the
--delta parameter if the value is negative.
Still require --shrink, because the operation is potentially
destructive.

commit id 'bd00e00e' neglected to add the new adapter source options
into the if condition that allowed printing the <source> XML fields.
The <adapter type='fc_host'.../> doesn't require other options in order
to be complete.
Some virsh commands have a size parameter, which is handled as scaled
integer. We don't have any *feature* that would allow to use '-1' as
maximum size, so it's safe to reject any negative values for those
commands.

The option didn't have VSH_OT_INT type even thought it's expected
to be numeric, as shown by the fact that vshCommandOptInt() is later
used to retrieve its value.
Replace more than 30 ad-hoc error messages with a single, generic one
that contains the name of the option being processed and some hints
to help the user understand what could have gone wrong.

When parsing a cpulist, the virBitmapParse is used. On an invalid
bitmap an error is reported, but the error gets cleared
immediately by subsequent public APIs call, e.g. virDomainFree().
Moreover, we don't check whether bitmap fits into maximal CPU ID
on the host. Therefore the following examples failed without any
error:
# virsh vcpupin test3 1 aaa
# virsh vcpupin test3 1 1000

Since 0fa15b19 we have this variable SYNC_TIME which allows users to

Extend it to a universal helper used for clearing lists of any objects.
Note that the argument type is specifically void * to allow implicit
typecasting.
Additionally add a helper that works on non-NULL terminated arrays once
we know the length.
The --maximum option wasn't properly parsed and the equivalent flag
wasn't set. Fix this bug and also rewrite the way we check this option
by using new macro. The new approach is that --maximum requires
--config, no other combination is allowed, because they don't make sense.
The new error will be:
# virsh setvcpus test --maximum 10
error: Option --config is required by option --maximum

virDomainGetJobStats is able to report statistics of a completed
migration, however to get usable downtime and total time statistics both
hosts have to keep synchronized time. To provide at least some
estimation of the times even when NTP daemons are not running on both
hosts we can just ignore the time needed to transfer a migration cookie
to the destination host. The result will be also inaccurate but a bit
more predictable. The total/down time will just be at least what we
report.

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 :)

In virsh we have two printing functions: vshPrint() which prints a
string onto stdout and vshPrintExtra() which does not print anything
if virsh is run in quiet mode. Usually, the former is used to print
actual results, while the latter to print strings like table headers
and other formatting stuff. However, in cmdDomIfAddr we have
mistakenly used vshPrintExtra even for actual data. After this patch,
the output should look like the following:
# virsh -q domifaddr test3 --source agent

As described in virDomainBlockCopy() parameters description, the
VIR_DOMAIN_BLOCK_COPY_GRANULARITY parameter may require the value to
have some specific attributes (e.g. be a power of two or fall within a
