c001eb5bbe virsh: Do not check the input XML at virsh layer for cmdDetachDevice
Any device XML doesn't use the same order as libvirt generates, or
uses decimal for attributes like "slot" of "<address>" will cause
device detaching to fail, as virsh compares the XML simply earlier
in strict manner before internal parsing.

This is regression introduced by ea7182c.

6152c74595 virsh: Plug memory leak on cmdUndefine
Detected by valgrind. Leak is introduced in commit 3bb6bcf.

Free 'vol' memory before allocating memory, the codes will miss one time
free when 'vol_i = nvolumes' in for loop, so plug memory leak.

* tools/virsh.c: fix memory leak on cmdUndefine.

* How to reproduce?
% dd if=/dev/null of=/var/lib/libvirt/images/foo bs=1 count=1 seek=10M
% virsh define foo.xml                   (disk source file points to '/var/lib/libvirt/images/foo')
% virsh vol-clone foo foo-clone default  (the original guest name is 'foo')
% virsh pool-refresh default
% virsh vol-list default                 (make sure 'foo-clone' volume exists)
% virsh define foo-clone.xml             (disk source file points to '/var/lib/libvirt/images/foo-clone')
% valgrind -v --leak-check=full virsh undefine foo-clone --remove-all-storage

* Actual results:

1. virsh output
Domain foo-clone has been undefined
Volume '/var/lib/libvirt/images/foo-clone' removed.

error: Failed to disconnect from the hypervisor, 1 leaked reference(s)

2. valgrind result

54a38915d8 Add a virt-host-validate command to sanity check HV config
To assist people in verifying that their host is operating in an
optimal manner, provide a 'virt-host-validate' command. For each
type of hypervisor, it will check any pre-requisites, or other
good recommendations and report what's working & what is not.

eg

  # virt-host-validate
  QEMU: Checking for device /dev/kvm                                         : FAIL (Check that the 'kvm-intel' or 'kvm-amd' modules are loaded & the BIOS has enabled virtualization)
  QEMU: Checking for device /dev/vhost                                       : WARN (Load the 'vhost_net' module to improve performance of virtio networking)
  QEMU: Checking for device /dev/net/tun                                     : PASS
   LXC: Checking for Linux >= 2.6.26                                         : PASS

This warns people if they have vmx/svm, but don't have /dev/kvm. It
also warns about missing /dev/vhost net.

7b4e5693c1 API: make declaration of _LAST enum values conditional
Although this is a public API break, it only affects users that
were compiling against *_LAST values, and can be trivially
worked around without impacting compilation against older
headers, by the user defining VIR_ENUM_SENTINELS before using
libvirt.h.  It is not an ABI break, since enum values do not
appear as .so entry points.  Meanwhile, it prevents users from
using non-stable enum values without explicitly acknowledging
the risk of doing so.

Domain IDs are at least 16 bits for most hypervisors, theoretically

Increase alignment to 5 characters to allow 16-bit domain IDs to
display cleanly. Commonly seen with LXC where domain IDs are the
process IDs by default.  Also increase the 'name' field from 20
to 30 characters to cope with longer guest names which are quite
common

4e9953a426 snapshot: allow reuse of existing files in disk snapshot
When disk snapshots were first implemented, libvirt blindly refused
to allow an external snapshot destination that already exists, since
qemu will blindly overwrite the contents of that file during the
snapshot_blkdev monitor command, and we don't like a default of
data loss by default.  But VDSM has a scenario where NFS permissions
are intentionally set so that the destination file can only be
created by the management machine, and not the machine where the
guest is running, so that libvirt will necessarily see the destination
file already existing; adding a flag will allow VDSM to force the file
reuse without libvirt complaining of possible data loss.

8e7829f754 virsh: Move job watch code to a separate function
called vshWatchJob. This can be later used in other
job oriented commands like dump, save, managedsave
to report progress and allow user to cancel via ^C.

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.
