96b3716c2a virsh: move version command to host group
Trivial patch, move version command to host commands group.

It has no any related with any domain.

It may connect to the daemon, so the flag is 0 but not VSH_CMD_FLAG_NOCONNECT.

1f24ddf6bf docs: Move 'echo' command description into the generic commands section
Virsh's echo command looks not having any relations with domains and its
description should go into the generic commands section instead of the
domain commands section (current).

3bb6bcfc79 virsh: Add option to undefine storage with domains
Add an option for virsh undefine command, to remove associated storage
volumes while undefining a domain. This patch allows the user to remove
associated (libvirt managed ) storage volumes while undefining a domain.

The new option --storage for the undefine command takes a string
argument that consists of comma separated list of target or source path
of volumes to be undefined. Volumes are removed after the domain has
been successfully undefined,

If a volume is not part of a storage pool, the user is warned to remove
the volume in question himself.

Option --wipe-storage may be specified along with this, that ensures
the image is wiped before removing.

Option --remove-all-storage enables the user to remove all storage. The
name is chosen long as the users should be aware what they're about to
do.

972f7e6e49 docs: tweak 'virsh edit' wording
I was wondering why 'virsh edit' didn't support the same
'--inactive' option as 'virsh dumpxml'; reading the source
code showed that --inactive was already implied, and that
the only way to alter a running guest rather than affecting
next boot is by hot-plugging individual devices, or by
something complex like saving the guest and modifying the
save image.

* tools/virsh.pod (define, edit): Mention behavior when guest is
already running.

104046712f build: follow directory install conventions
Commit 4d9e51f6 fixed a 'make uninstall' failure, but failed
to follow other conventions already present in src/Makefile.am.
In particular, we prefer MKDIR_P over mkdir -p, and should
have a matching rmdir during uninstall for every directory
created during install (the idea being that uninstall in a
DESTDIR should be clean, while installation in the final
system should not fail with non-empty directories left behind).

22cf6d46f4 qemu: amend existing table of device weights
Prior to this patch, for a running dom, the commands:

$ virsh blkiotune dom --device-weights /dev/sda,502,/dev/sdb,498
$ virsh blkiotune dom --device-weights /dev/sda,503
$ virsh blkiotune dom
weight         : 500
device_weight  : /dev/sda,503

claim that /dev/sdb no longer has a non-default weight, but
directly querying cgroups says otherwise:

$ cat /cgroup/blkio/libvirt/qemu/dom/blkio.weight_device
8:0     503
8:16    498

After this patch, an explicit 0 is required to remove a device path
from the XML, and omitting a device path that was previously
specified leaves that device path untouched in the XML, to match
cgroups behavior.

* src/qemu/qemu_driver.c (parseBlkioWeightDeviceStr): Rename...
(qemuDomainParseDeviceWeightStr): ...and use correct type.
(qemuDomainSetBlkioParameters): After parsing string, modify
rather than replacing existing table.

6ac81c8ec8 blkiotune: add interface for blkiotune.device_weight
This adds per-device weights to <blkiotune>.  Note that the
cgroups implementation only supports weights per block device,
and not per-file within the device; hence this option must be
global to the domain definition rather than tied to individual
<devices>/<disk> entries:

<domain ...>
  <blkiotune>
    <device>
      <path>/path/to/block</path>
      <weight>1000</weight>
    </device>
  </blkiotune>
..

This patch also adds a parameter --device-weights to virsh command
blkiotune for setting/getting blkiotune.weight_device for any
hypervisor that supports it.  All <device> entries under
<blkiotune> are concatenated into a single string attribute under
virDomain{Get,Set}BlkioParameters, named "device_weight".

4789fb2e4e Add support for systemd init service
This patch adds support for a systemd init service for libvirtd
and libvirt-guests. The libvirtd.service is *not* written to use
socket activation, since we want libvirtd to start on boot so it
can do guest auto-start.

The libvirt-guests.service is pretty lame, just exec'ing the
original init script for now. Ideally we would factor out the
functionality, into some shared tool.

Instead of

  ./configure --with-init-script=redhat

You can now do

  ./configure --with-init-script=systemd

Or better still:

  ./configure --with-init-script=systemd+redhat

We can also now support install of the upstart init script

* configure.ac: Add systemd, and systemd+redhat options to
  --with-init-script option
* daemon/Makefile.am: Install systemd services
* daemon/libvirtd.sysconf: Add note about unused env variable
  with systemd
* daemon/libvirtd.service.in: libvirtd systemd service unit
* libvirt.spec.in: Add scripts to installing systemd services
  and migrating from legacy init scripts
* tools/Makefile.am: Install systemd services
* tools/libvirt-guests.init.sh: Rename to tools/libvirt-guests.init.in
* tools/libvirt-guests.service.in: systemd service unit

1ae8eed1b4 virsh: add iface-bridge and iface-unbridge commands
One of the top questions by libvirt users is how to create a host
bridge device so that guests can be directly on the physical
network. There are several example documents that explain how to do
this manually, but following them often results in confusion and
failure. virt-manager does a good job of creating a bridge based on an
existing network device, but not everyone wants to use virt-manager.

This patch adds a new command, iface-bridge that makes it just about
as simple as possible to create a new bridge device based on an
existing ethernet/vlan/bond device (including associating IP
configuration with the bridge rather than the now-attached device),
and start that new bridge up ready for action, eg:

    virsh iface-bridge eth0 br0

For symmetry's sake, it also adds a command to remove a device from a
bridge, restoring the IP config to the now-unattached device:

    virsh iface-unbridge br0

(I had a short debate about whether to do "iface-unbridge eth0"
instead, but that would involve searching through all bridge devices
for the one that contained eth0, which seems like a bit too much
trouble).

NOTE: These two commands require that the netcf library be available
on the host. Hopefully this will provide some extra incentive for
people using suse, debian, ubuntu, and other similar systems to polish
up (and push downstream) the ports to those distros recently pushed to
the upstream netcf repo by Dan Berrange. Anyone interested in helping
with that effort in any way should join the netcf-devel mailing list
(subscription info at
https://fedorahosted.org/mailman/listinfo/netcf-devel)

During creation of the bridge, it's possible to specify whether or not
the STP protocol should be started up on the bridge and, if so, how
many seconds the bridge should squelch traffic from newly added
devices while learning new topology (defaults are stp='on' and
delay='0', which seems to usually work best for bridges used in the
context of libvirt guests).

There is also an option to not immediately start the bridge (and a
similar option to not immediately start the un-attached device after
destroying the bridge. Default is to start the new device, because in
the case of iface-unbridge not starting is strongly discouraged as it
will leave the system with no network connectivity on that interface
(because it's necessary to destroy/undefine the bridge device before
the unattached device can be defined), and it seemed better to make
the option for iface-bridge behave consistently.

NOTE TO THOSE TRYING THESE COMMANDS FOR THE FIRST TIME: to guard
against any "unexpected" change to configuration, it is advisable to
issue an "virsh iface-begin" command before starting any interface
config changes, and "virsh iface-commit" only after you've verified
that everything is working as you expect. If something goes wrong,
you can always run "virsh iface-rollback" or reboot the system (which
should automatically do iface-rollback).

Aside from adding the code for these two functions, and the two
entries into the command table, the only other change to virsh.c was
to add the option name to vshCommandOptInterfaceBy(), because the
iface-unbridge command names its interface option as "bridge".

virsh.pod has also been updated with short descriptions of these two
new commands.

2d764cb472 virsh: Add VSH_OFLAG_EMPTY_OK for attach-disk command
As the description of removing CDROM media from
  http://wiki.libvirt.org/page/QEMUSwitchToLibvirt#eject_DEV

Add flag 'VSH_OFLAG_EMPTY_OK' to the option 'source' of attach-disk

Then avoid outputting <source> in the XML if 'source' was empty,
rather than trusting libvirt domain_conf.c to understand an empty
string.

6b5c9936ec virsh: Fix error message on vol-create-from failure
If vol-create-from is failed due to 'input volume not found',
virsh outputs like this:
  $ sudo virsh vol-create-from testpool test-vol.xml test.img
  error: failed to get vol 'test.img', specifying --pool might help
  error: Storage volume not found: no storage vol with matching path
However, '--pool' is incorrect because it is already specified as
second argument ('testpool' in this case). It should be "--inputpool".

The patch fixes this by using pooloptname, which will be "inputpool"
in this case and "pool" in other cases, as error message.

9981fc5828 virsh: Fix vol-info's 'Type' output
We have a new vol type "dir" in addition to "file" and "block", but
virsh doesn't know it. Fix it.

Additionally, the patch lets virsh output "unknown" if not matched
any of them.

10d3272ec3 docs: document managed=yes of hostdev passthrough
Clarify some of the effects of managed passthrough <hostdev> devices;
with recent changes (commit d093547), a nodedev-reattach is only needed
to pair up to an explicit nodedev-dettach (but beware that older
virt-manager has a bug where it uses explicit nodedev-dettach under the
hood when using the gui to hotplug a hostdev device).

* docs/formatdomain.html.in: Mention reattach.
* tools/virsh.pod (nodedev): Mention managed mode.
