After commit 8aecd35126 it'll detect
that a required option is not defined and it will assert and exit with:
virsh.c:1364: vshCommandOpt: Assertion `valid->name' failed.
Problem has been latent since commit ed23b106.

Currently the virConnectBaselineCPU API does not expose the CPU features
that are part of the CPU's model. This patch adds a new flag,
VIR_CONNECT_BASELINE_CPU_EXPAND_FEATURES, that causes the API to explicitly
list all features that are part of that model.

Use the virDomainSetMemoryStatsPeriodFlags() to pass a period defined by
usage of a new --period option in order to set the collection period for the
balloon driver. This may enable or disable the collection based on the value.
Add the --current, --live, & --config options to dommemstat.
Paolo Bonzini pointed out that it's actually possible to migrate a qemu
instance that was paused due to I/O error and it will be able to work on
the destination if the storage is accessible.
This patch introduces flag VIR_MIGRATE_ABORT_ON_ERROR that cancels the
migration in case an I/O error happens while it's being performed and
allows migration without this flag. This flag can be possibly used for
other error reasons that may be introduced in the future.
This patch fixes changes done in commit 29c1e913e4
that was pushed without implementing review feedback.
The flag introduced by the patch is changed to VIR_DOMAIN_VCPU_GUEST and
documentation makes the difference between regular hotplug and this new
functionality more explicit.
The virsh options that enable the use of the new flag are changed to
"--guest" and the documentation is fixed too.
This flag will allow to use qemu guest agent commands to disable
(offline) and enable (online) processors in a live guest that has the
guest agent running.
Explicitly state that using incomplete XML definition snippets for hot-management
commands may have unexpected results due to autogenerating values for some of
the fields if they aren't specified explicitly.
Newer pod (hello rawhide) complains if you attempt to mix bullets
and non-bullets in the same list:
virsh.pod around line 3177: Expected text after =item, not a bullet
As our intent was to nest an inner list, we make that explicit to
keep pod happy.
* tools/virsh.pod (ENVIRONMENT): Use correct pod syntax.
virsh schedinfo was able to set only one parameter at a time (not
counting the deprecated options), but it is useful to set more at
once, so this patch adds the possibility to do stuff like this:
virsh schedinfo <domain> cpu_shares=0 vcpu_period=0 vcpu_quota=0 \
emulator_period=0 emulator_quota=0
Invalid scheduler options are reported as well. These were previously
reported only if the command hadn't updated any values (when
cmdSchedInfoUpdate returned 0).

The virsh(1) man page wasn't saying anything about the 'migrateuri'
parameter other than it can be usually omitted. A patched version of
docs/migrate.html.in is taken in this patch to fix that up in the man
page.
The man page states that with --config the next boot is affected. This
can be understood as if _only_ the next boot was affected. This isn't
true if the machine is running.
This patch adds the full --live, --config, --current infrastructure and
tweaks stuff to correctly support the obsolete --persistent flag.
Note that this patch changes the the behavior of the --config flag to match the
use of this flag in rest of libvirt. This flag was mistakenly renamed from
--persistent that originaly had different semantics.
VIR_CONNECT_LIST_NODE_DEVICES_CAP_FC_HOST to filter the FC HBA,
and VIR_CONNECT_LIST_NODE_DEVICES_CAP_VPORTS to filter the FC HBA
which supports vport.
The docs assumed the command works always for QEMU and other
hypervisors. As this is done using the balloon mechainism live increase
of the maximum memory limit isn't supported. Fix the docs to mention
this limitation.
Clarify that net-create deals with a transient virtual

When a disk-only snapshot is requested the domain is treated as if it
was offline. This forbids to mix memory checkpoints with the DISK_ONLY
flag.
This patch improves the error message and mentions the restriction in
the virsh man page.

Offline migration transfers inactive definition of a domain (which may
or may not be active). After successful completion, the domain remains
in its current state on source host and is defined but inactive on
destination host. It's a bit more clever than virDomainGetXMLDesc() on
source host followed by virDomainDefineXML() on destination host, as
offline migration will run pre-migration hook to update the domain XML
on destination host. Currently, copying non-shared storage is not
supported during offline migration.
Offline migration can be requested with a new migration flag called
VIR_MIGRATE_OFFLINE (which has to be combined with
VIR_MIGRATE_PERSIST_DEST flag).
As we enable more modes of snapshot creation, it becomes more important
to be able to quickly filter based on snapshot properties. This patch
introduces new filter flags; subsequent patches will introduce virsh
back-compat filtering, as well as actual libvirt filtering.
* include/libvirt/libvirt.h.in (virDomainSnapshotListFlags): Add
five new flags in two new groups.
* src/libvirt.c (virDomainSnapshotNum, virDomainSnapshotListNames)
(virDomainListAllSnapshots, virDomainSnapshotNumChildren)
(virDomainSnapshotListChildrenNames)
(virDomainSnapshotListAllChildren): Document them.
* src/conf/snapshot_conf.h (VIR_DOMAIN_SNAPSHOT_FILTERS_STATUS)
(VIR_DOMAIN_SNAPSHOT_FILTERS_LOCATION): Add new convenience filter
collection macros.
* tools/virsh-snapshot.c (cmdSnapshotList): Add 5 new flags.
* tools/virsh.pod (snapshot-list): Document them.
This reverts commits 5f63a5cb42
and ff86b0c97b. After much list
discussion, consensus was that libvirt aliases should be reserved
to correct typos, otherwise it risks confusion. Rather, we
should implement a way for users to provide their own aliases
as part of their virsh configuration preferences.
External checkpoints could be created with snapshot-create, but
without libvirt supplying a default name for the memory file,
it is essential to add a new argument to snapshot-create-as to
allow the user to choose the memory file name. This adds the
option --memspec [file=]name[,snapshot=type], where type can
be none, internal, or external. For an example,
virsh snapshot-create-as $dom --memspec /path/to/file
is the shortest possible command line for creating an external
checkpoint, named after the current timestamp.
* tools/virsh-snapshot.c (vshParseSnapshotMemspec): New function.
(cmdSnapshotCreateAs): Use it.
* tests/virsh-optparse (test_url): Test it.
* tools/virsh.pod (snapshot-create-as): Document it.
Make it clear that the alternate terms have no difference except
for length of time they were supported.
* tools/virsh.pod (start, shutdown, reboot): More documentation.
