4c4b821ec3 Rewrite vshPrintPinInfo
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.

f4b5f53027 virsh: domain: Fix the change-media command
The command did not modify the disk type and thus didn't allow to change
media from a file image to a block backed image or vice versa. In
addition when operating on a network backed removable devices the
command would replace the while <source> subelement with an invalid one.

This patch adds the --block option that allows to specify that the new
image is block backed and assumes that without that option all images
are file backed. Since network backends were always mangled it should
not cause problems.

Since cmdDetachDisk() calls into vshPrepareDiskXML() with

into skipping all the checks and effectively turn the function into a
XML formatter.

This patch changes the code to use the formatter directly so that the
function can be refactored in a easier way.

ceec58ac9e virsh: fix report of non-active commit completion
Commit f182da20 (v1.2.6) caused a slight regression in virsh
reporting of a non-active block job; where it used to state
"Commit complete", it now states "Now in synchronized phase".
But the synchronized phase is only possible for an active commit.

For a reproducer, I created a chain 'a <- b <- c <- d <- e' and
ran virsh blockcommit $dom vda --top c --base a --verbose --wait

* tools/virsh-domain.c (cmdBlockCommit): Synchronized phase is

1cfc0a9990 virsh: Add iothreadpin command
https://bugzilla.redhat.com/show_bug.cgi?id=1135491

$ virsh iothread --help

  NAME
    iothreadpin - control domain IOThread affinity

  SYNOPSIS
    iothreadpin <domain> <iothread> <cpulist> [--config] [--live] [--current]

  DESCRIPTION
    Pin domain IOThreads to host physical CPUs.

  OPTIONS
    [--domain] <string>  domain name, id or uuid
    [--iothread] <number>  IOThread ID number
    [--cpulist] <string>  host cpu number(s) to set
    --config         affect next boot
    --live           affect running domain
    --current        affect current domain

Using the output from iothreadsinfo, allow changing the pinned CPUs for
a single IOThread.

$ virsh iothreadsinfo $dom
 IOThread ID    CPU Affinity
---------------------------------------------------
 1               2
 2               3
 3               0-1

$ virsh iothreadpin $dom 3 0-2

Then view the change

$ virsh iothreadsinfo $dom
 IOThread ID    CPU Affinity
---------------------------------------------------
 1               2
 2               3
 3               0-2

If an invalid value is supplied or require option missing,
then an error will be displayed:

$ virsh iothreadpin $dom 4 3
error: invalid argument: iothread value out of range 4 > 3

$ virsh iothreadpin $dom 3

Add the 'iothreadsinfo' command to display IOThread Info data. Allow for
[--live] or [--config] options in order to display live or config data
for an active domain.

$ virsh iothreadsinfo --help
  NAME
    iothreadsinfo - view domain IOThreads

  SYNOPSIS
    iothreadsinfo <domain> [--config] [--live] [--current]

  DESCRIPTION
    Returns basic information about the domain IOThreads.

  OPTIONS
    [--domain] <string>  domain name, id or uuid
    --config         affect next boot
    --live           affect running domain
    --current        affect current domain

An active domain may return:

$ virsh iothreads $dom
 IOThread ID     CPU Affinity
---------------------------------------------------
  1               2
  2               3
  3               0

$ echo $?
0

For domains which don't have IOThreads the following is returned:

$ virsh iothreads $dom
No IOThreads found for the domain

$ echo $?
0

For domains which are not running the following is returned:

$ virsh iothreads $dom --live
error: Unable to get domain IOThreads information
error: Requested operation is not valid: domain is not running

$ echo $?
1

Editing a domains configuration and modifying the iothreadpin data for
thread 3 from nothing provided to setting a cpuset of '0-1' and then
displaying using --config would display:

$ virsh iothreads f18iothr --config
 IOThread ID     CPU Affinity
 ----------------------------
  1               2
  2               3
  3               0-1

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.

d7565bd8aa virsh: add support for domain XML validation
The 'virsh edit' command gets XML validation enabled by default,
with a --skip-validate option to disable it. The 'virsh define'
and 'virsh create' commands get a --validate option to enable
it, to avoid regressions for existing scripts.

The quality of error reporting from libxml2 varies depending
on the type of XML error made. Sometimes it is quite clear
and useful, other times it is obscure & inaccurate. At least
the user will see an error now, rather than having their
XML modification silently disappear.

When a block{pull, copy, commit} is aborted via keyboard interrupt,

However, when the job receives an abort from another client connected

took effect. This patch introduces a new blockjob abort handler, which
is registered when the client calls block{copy,commit,pull} routine,

9cc1586d2b qemu: Memory pre-pinning support for RDMA migration
RDMA Live migration requires registering memory with the hardware, and
thus QEMU offers a new 'capability' to pre-register / mlock() the guest
memory in advance for higher RDMA performance before the migration
begins. This capability is disabled by default, which means QEMU will
register the memory with the hardware in an on-demand basis.

This patch exposes this capability with the following example usage:

be365d8dff virsh: Resolve Coverity NEGATIVE_RETURNS
Coverity notes that after we VIR_ALLOC_N(params, nparams) a failed call to
virDomainGetCPUStats could result in nparams being set to -1. In that case,
the subsequent virTypedParamsFree in cleanup will pass -1 which isn't good.

Use the returned value as the number of stats to display in the loop as
it will be the value reported from the hypervisor and may be less than
nparams which is OK
