416d0e9418 cmdVcpuPin: Remove dead code
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,
the condition could make sense if it is rewritten as the following:

!(flags & VIR_DOMAIN_AFFECT_CONFIG) && virDomainIsActive(dom)

848ab685f7 virsh: report error if vcpu number exceed the guest maxvcpu number
Commit id '81dd81e' caused a regression when attempting to print a
specific vcpuid that is out of the range of the maximum vcpus for
the guest, such as:

 $ virsh vcpupin $dom 1000
 VCPU: CPU Affinity
 ----------------------------------

 $

Rather than just recover the old message, let's adjust the message based
on what would be displayed for a similar failure in the set path, such as:

 $ virsh vcpupin $dom 1000
 error: vcpu 1000 is out of range of persistent cpu count 2

 $ virsh vcpupin $dom 1000 --live
 error: vcpu 1000 is out of range of live cpu count 2

When the block job would fail while watching it using the "--wait"
option for blockcopy, virsh would rather unhelpfully report:

Add a special case when the block job vanishes while waiting for it to
finish to improve the message:

e9507fd41c virsh: Fix Ctrl-C behavior when watching a job
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.

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 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:

aa9f139599 migration: Usable time statistics without requiring NTP
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.

31ef0836a7 virsh: fix regression in 'virsh event' by domain
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 :)

81dd81e475 virsh: fix vcpupin info
The "virDomainGetInfo" will get for running domain only live info and for
offline domain only config info. There was no way how to get config info
for running domain. We will use "vshCPUCountCollect" instead to get the
correct cpu count that we need to pass to "virDomainGetVcpuPinInfo".

Also cleanup some unnecessary variables and checks that are done by
drivers.

1bb1de83b2 virsh-edit: Make force editing usable
When editing a domain with 'virsh edit' and failing validation, the
usual message pops up:

  Failed. Try again? [y,n,f,?]:

Turning off validation can be useful, mainly for testing (but other
purposes too), so this patch adds support for relaxing definition in
virsh-edit and makes 'virsh edit <domain>' more usable.

e008a03324 virsh attach-interface: Allow macvtap hotplug
Our hotplug code supports macvtap insertion to guests. However, we
somehow forgot about 'attach-interface' (which tries to build XML from
passed arguments and use virDomainAttachDeviceFlags()).
New type is accessible under 'direct' type, to keep the same type as
used in domain XML.

dd6668f174 virsh attach-interface: Use virDomainNetType{From,To}String()
Instead of verbose string to enum conversion (if STREQ() else if
STREQ() else if STREQ() ...) lets use virDomainNetType{From,To}String.

18bcba55cd virsh attach-interface: Use enum instead of arbitrary integers
The type of interface to attach is held in the variable 'typ'.
Depending on interface type selected by user, the variable is set
either to 1 (network), or 2 (bridge). Lets use already existing
enum from domain_conf.h instead: virDomainNetType.

1ba8156cc9 virsh: fix IP address in domdisplay for listen type='network'
https://bugzilla.redhat.com/show_bug.cgi?id=1191016

virsh's domdisplay command looks in /domain/devices/graphics/@listen
of the domain's XML for the listen address, however for listen
type='network' (added in libvirt 0.9.4), the <graphics> element
doesn't have a listen attribute, but has a <listen> subelement,
*still* with no address (this is the inactive XML):

 <graphics type='spice' autoport='yes' keymap='en-us'>
  <listen type='network' network='default'/>
 </graphics>

However, at domain start time the <listen> subelement gets its address
attribute filled in once libvirt figures out the IP address associated
with the named network (this is the status XML):

 <graphics type='spice' port='5901' autoport='yes' keymap='en-us'>
  <listen type='network' address='192.168.122.1' network='default'/>
 </graphics>

So in these cases, we need to look at
/domain/devices/graphics/listen/@address instead.

Even though another patch is being pushed that will backfill
listen/@address into @listen, this patch is still useful, as it fixes
domdisplay for cases of a new virsh (with this patch) connecting to a
libvirtd that is newer than 0.9.4 but doesn't have the followup patch.

4b4c7208c9 S390: ccw support for virsh attach-disk address parameter
Adding ccw bus address support to the optional address parameter of virsh
attach-disk. The format used is ccw:cssid. ssid.devno, e.g.
ccw:0xfe.0x0.0x0201

Virtio-ccw devices must have their cssid set to 0xfe.
