704dfd6b0f virsh: avoid unnecessary progress updates
There is no need to call virshPrintJobProgress() unless the block job's
cur or end cursors have changed since the last iteration.

63cdc92f04 storage: Add TRIM algorithm to storage volume API
This new algorithm adds support for wiping volumes using TRIM.

It does not overwrite all the data in a volume, but it tells the
backing storage pool/driver that all bytes in a volume can be
discarded.

It depends on the backing storage pool how this is handled.

A SCSI backend might send UNMAP commands to remove all data present
on a LUN.

A Ceph backend might use rbd_discard() to instruct the Ceph cluster
that all data on that RBD volume can be discarded.

985f01a65f virsh: fix cpu-stats command output format issue
After commit 57177f1, the cpu-stats command format change to:

CPU0:

    vcpu_time    14378732785511

vcpu_time is not user friendly. After this patch, it will
change back:
CPU0:
    cpu_time         14401.507878990 seconds
    vcpu_time        14378.732785511 seconds

virDomainGetCPUStats doesn't support flags so there's no need to carry
the 'flags' variable around. Additionally since the API is poorly

d55e11a302 virt-host-validate: Check those CGroups that we actually use
Since the introduction of virt-host-validate tool the set of
cgroup controllers we use has changed so the tool is checking for
some cgroups that we don't need (e.g. net_cls, although I doubt
we have ever used that one) and is not checking for those we

9cbd1ecc3e virsh: Correctly detect inserted media in change-media command
https://bugzilla.redhat.com/show_bug.cgi?id=1250331

It all works like this. The change-media command dumps domain
XML, finds the corresponding cdrom device we want to change media
in and returns it in the xmlNodePtr form. This way we don't have
to bother with keeping all the subelements or attributes that we
don't care about in the XML that is fed back to libvirt for the
update API.

Now, the problem is we try to be clever here and detect if disk
already has a source (indicated by <source/> subelement).
However, bare fact that the element is there does not mean disk
has source. Make our clever check better.

3bd2ee5d55 virsh: Don't fetch status for all domains in cmdList
We are getting the list of domains and after that we iterate over
the list and try to get status for each domain hoping it will
skip over domains that disappeared meanwhile. However, this
solution to race is bogus - domain may disappear right after we
have checked its state and before we exec another API over it
(e.g. virDomainHasManagedSaveImage()). Also, when printing just
names or uuids (list --name / --uuid) we issue APIs to obtain the
values, however these require no RPC call as all requested info
is in virDomain object that client already has.
Therefore move the status obtaining only to the place that really
needs it.

70c6e67766 virsh: Adjustments for the VIRSH_COMMON_OPT_POOL
The macro is slightly adjusted to add an argument "_helpstr". This
will be passed as a translation macro string since other uses of the
option may not have the same exact help string (such as is the case
when the uuid is not suppliable for create commands).

In virsh-pool.c - we'll create a singular VIRSH_COMMON_OPT_POOL_FULL
in order to pass along the 'N_("pool name or uuid")'

In virsh-volume.c there will be a VIRSH_COMMON_OPT_POOL_FULL and a
VIRSH_COMMON_OPT_POOL_NAME, which passes 'N_("pool name")' for
the commands that can only pass a name. There will also be a
VIRSH_COMMON_OPT_POOL_OPTIONAL which is used for the command
options which use OT_STRING and don't require the --pool argument.

3245e1783c Revert "admin: Rename virAdmConnect to virAdmDaemon"
Commmit df8192aa introduced admin related rename and some minor
(caused by automated approach, aka sed) and some more severe isues along with
it. First reason to revert is the inconsistency with libvirt library.
Although we deal with the daemon directly rather than with a specific
hypervisor, we still do have a connection. That being said, contributors might
get under the impression that AdmDaemonNew would spawn/start a new daemon
(since it's admin API, why not...), or AdmDaemonClose would do the exact
opposite or they might expect DaemonIsAlive report overall status of the daemon
which definitely isn't the case.
The second reason to revert this patch is renaming virt-admin client. The
client tool does not necessarily have to reflect the names of the API's it's
using in his internals. An example would be 's/vshAdmConnect/vshAdmDaemon'
where noone can be certain of what the latter function really does. The former
is quite expressive about some connection magic it performs, but the latter does
not say anything, especially when vshAdmReconnect and vshAdmDisconnect were
left untouched.

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:
