To collect all balloon statistics for all guests it was necessary to make
several libvirt requests. Now it's possible to get all balloon statiscs via
single connectGetAllDomainStats call.

Crash dump in a old kvmdump format is being obsolete and cannot be loaded and
processed by crash utility since its version 6.1.0. A --memory-only option is
required in order to produce valid ELF file which can be later processed by the
crash utility. A new note is added to the dump command description.
Extend the lxc-enter-namespace command so that it joins the
containers' cgroups before starting new namespaces. This

Use vshCommandOptScaledInt instead of vshCommandOptULongLong so that
values with suffixes can be passed when bytes are being passed along.
Values for the iops parameters still need to be given in the absolute
form as they are not bytes but numbers.

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.

reason to make 'perf' command an exception. Currently, it accepts

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.

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.

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.

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:

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.

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
virsh #

We have a function parseRateStr() that parses --inbound and

Now that we have all virTypedParams macros needed for QoS,
lets parse even floor attribute. The extended format for the

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:
# virsh setvcpus test --maximum 10
error: Option --config is required by option --maximum

As described in virDomainBlockCopy() parameters description, the
VIR_DOMAIN_BLOCK_COPY_GRANULARITY parameter may require the value to
have some specific attributes (e.g. be a power of two or fall within a
certain range). And in qemu, a power of two is required. However, our
code does not check that and let qemu operation fail. Moreover, the
virsh man page is not as exact as it could be in this respect.
