73a2510feb virsh: man: Do not document our old deprecated nodedev-dettach command
The command is deprecated due to being grammatically incorrect, but for
backwards compatibility reasons cannot be removed. However, we should not
document such commands.

2197ea56d7 conf: Add IOThread quota and period scheduler/cputune defs
https://bugzilla.redhat.com/show_bug.cgi?id=1356937

Add the definitions to allow for viewing/setting cgroup period and quota
limits for IOThreads.

This is similar to the work done for emulator quota and period by
commit ids 'b65dafa' and 'e051c482'.

Being able to view/set the IOThread specific values is related to more
recent changes adding global period (commmit id '4d92d58f') and global
quota (commit id '55ecdae') definitions and qemu support (commit id
'4e17ff79' and 'fbcbd1b2'). With a global setting though, if somehow
the IOThread value in the cgroup hierarchy was set "outside of libvirt"
to a value that is incompatible with the global value.

Allowing control over IOThread specific values provides the capability
to alter the IOThread values as necessary.

ed504ba392 virDomain{Get,Set}PerfEvents: support --config --live --current
Now that we have @flags we can support changing perf events just
in active or inactive configuration regardless of the other.
Previously, calling virDomainSetPerfEvents set events in both
active and inactive configuration at once. Even though we allow
users to set perf events that are to be enabled once domain is
started up. The virDomainGetPerfEvents API was flawed too. It
returned just runtime info.

f486cb5ea0 migration: add target peer disks port
Some hypervisors (namely qemu) can have a separate connecton for
non-shared disks migration of active domains. Currently we have
no means to control the port of such a connection. At the same
time we have options to control port of memory migration traffic
(thru migration uri) as well as interfaces that target server
is bound to for incoming migration (thru VIR_MIGRATE_PARAM_LISTEN_ADDRESS).
Let's add the option for setting disks port too.

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.

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:
