deb3e802de virsh: Document the --timestamp option
The event, net-event and qemu-monitor-event virsh commands all
support the --timestamp option now, but such option was not
referenced in the man page.

2eba5c5635 virsh: Add --delete-snapshots flag for undefine and vol-delete
https://bugzilla.redhat.com/show_bug.cgi?id=1281710

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.

e193735450 virsh: Add build flags to pool-create[-as] and pool-start
https://bugzilla.redhat.com/show_bug.cgi?id=830056

Utilize recently added VIR_STORAGE_POOL_CREATE_WITH_BUILD* flags in
order to pass the flags along to the virStoragePoolCreateXML and
virStoragePoolCreate API's.

This affects the 'virsh pool-create', 'virsh pool-create-as', and
'virsh pool-start' commands.  While it could be argued that pool-start
doesn't need the flags, they could prove useful for someone trying to
do one command build --overwrite and start command processing or
essentially starting with a clean slate.

NB:
This patch is loosely based upon code originally authored by Osier
Yang that were not reviewed and pushed, see:

a9a583d6df virsh-domain: update attach-interface to support type=hostdev
Adding this feature will allow users to easily attach a hostdev network
interface using PCI passthrough.

The interface can be attached using --type=hostdev and PCI address or
as --source.  This command also allows you to tell, whether the interface
should be managed.

ff486e0d29 virsh: Implement "domrename" command
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.

Example:

virsh # list --all
 Id    Name                           State
 ----------------------------------------------------
  -     bar                            shut off

virsh # domrename bar foo
Domain successfully renamed

virsh # list --all
 Id    Name                           State
 ----------------------------------------------------
  -     foo                            shut off

a02a161bb8 qemu: libxl: vcpupin: Don't reset pinning when pinning to all pcpus
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.

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:

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.

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

6776a26e5c man: moved virsh command cpu-models
The description of the virsh command 'cpu-models' was written in the
wrong context (i.e. beside the domain states).
This patch moves the command description just to the cpu related
commands like 'cpu-baseline' and 'cpu-compare'.

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.

4bffafb2eb getstats: add new flag for block backing chain
This patch introduces access to allocation information about
a backing chain of a live domain.  While querying storage
volumes for read-only disks could provide some of the details,
we do NOT want to read() a file while qemu is writing it.
Also, there is one case where we have to rely on qemu: when
doing a block commit into a backing file, where that file is
stored in qcow2 format on a host block device, we want to know
the current highest write offset into that image, in order to
know if the disk must be resized larger.  qemu-img does not
(currently) show this information, and none of the earlier
block APIs were extensible enough to expose it.  But
virDomainListGetStats is perfect for the job!

We don't need a new group of statistics, as the existing block
group is sufficient.  On the other hand, as existing libvirt
releases already report 1:1 mapping of block.count to <disk>
devices, changing the array size could confuse older clients;
and even with newer clients, the time and memory taken to
report additional statistics is not always necessary (backing
files are generally read-only except for block-commit, so while
read statistics may change, sizing statistics will not).  So
the choice here is to add a new flag that only newer callers
will pass, when they are prepared for the additional information.

This patch introduces the new API, but it will take more
patches to get it implemented for qemu.

* include/libvirt/libvirt-domain.h
(VIR_CONNECT_GET_ALL_DOMAINS_STATS_BACKING): New flag.
* src/libvirt-domain.c (virConnectGetAllDomainStats): Document it,
and add a new field when it is in use.
* tools/virsh-domain-monitor.c (cmdDomstats): Use new flag.
* tools/virsh.pod (domstats): Document it.

7b499262cb getstats: add block.n.path stat
I'm about to make block stats optionally more complex to cover
backing chains, where block.count will no longer equal the number
of <disks> for a domain.  For these reasons, it is nicer if the
statistics output includes the source path (for local files).
This patch doesn't add anything for network disks, although we
may decide to add that later.

With this patch, I now see the following for the same domain as
in the previous patch (one qcow2 file, and an empty cdrom drive):
$ virsh domstats --block foo
Domain: 'foo'
  block.count=2
  block.0.name=hda
  block.0.path=/var/lib/libvirt/images/foo.qcow2
  block.1.name=hdc

* src/libvirt-domain.c (virConnectGetAllDomainStats): Document
new field.
* tools/virsh.pod (domstats): Document new field.
* src/qemu/qemu_driver.c (qemuDomainGetStatsBlock): Return the new
stat for local files/block devices.
(QEMU_ADD_NAME_PARAM): Add parameter.
(qemuDomainGetStatsInterface): Update caller.
