We allow translation from no_bandwidth to has_bandwidth for a vnic.
However, going in the opposite direction is not implemented. It's not
limitation of the API rather than internal implementation. The problem
is, we correctly detect that user hasn't specified any outbound (say
he wants to clear out outbound). However, this gets overwritten by
current vnic outbound settings. Then, virNetDevBandwidthSet doesn't
change anything. We need to stop overwriting the outbound if users
don't want us to. Same applies for inbound.

Introducing keepalive similarly to Guannan around 2 years ago.  Since
we want to introduce keepalive for every connection, it makes sense to
wrap the connecting function into new virsh one that can deal
keepalive as well.

Function vshConnect() is now used for connecting and keepalive added
in that function (if possible) helps preventing long waits e.g. while
nework goes down during migration.

This patch also adds the options for keepalive tuning into virsh and
fails connecting only when keepalives are explicitly requested and
cannot be set (whether it is due to missing support in connected
driver or remote server).  If not explicitely requested, a debug
message is printed (hence the addition to virsh-optparse test).

'virsh lxc-enter-namespace' does not have a way to reflect exit
status to the caller in single-command mode, but we might as well
at least report the exit status.  Prior to this patch,

$ virsh -c lxc:/// lxc-enter-namespace shell /bin/sh 'exit 3'; echo $?
1

now it gives some details:

$ virsh -c lxc:/// lxc-enter-namespace shell /bin/sh -c 'exit 3'; echo $?
error: internal error: Child process (31557) unexpected exit status 3
1

Also useful:

$ virsh -c lxc:/// lxc-enter-namespace shell /bin/sh -c 'kill $$'; echo $?
error: internal error: Child process (31585) unexpected fatal signal 15

Similar to our event-test demo program, it's nice to be able to
have a mode where we can sniff all events at once, rather than
having to spawn multiple virsh in parallel with one for each
event type.

(Can I just say our RegisterAny design is lousy?  The fact that
the majority of our callback pointers have a function signature
with the opaque data in a different position, and that we have
to cast the function signature before registering it, makes it
hard to write a generic callback function; we have to write one
for every type of event id.  Life would have been easier if we
had designed the callback as a fixed signature with a void*
and size parameter, and then allowed the caller to downcast
the void* to a particular struct for data specific to their
callback id, where we could have then had a single function
with a switch statement for each event id, and register that
one function for all types of events.  It would also be nicer
if the callback functions knew which callbackID was being used
when invoking that callback, so that I could use a common data
structure among all registrations instead of having to create
an array of one data per callback.  But I really don't want to
go add yet another event API design.)

Add 'virsh event --list' and 'virsh event [dom] --event=name
[--loop] [--timeout]'.  Borrows somewhat from event-test.c,
but defaults to a one-shot notification, and takes advantage
of the event loop integration to allow Ctrl-C to interrupt the
wait for an event.  For now, this just does lifecycle events.

Recent autotest/virt-test testing on f20 discovered an anomaly in how
the bandwidth options are documented and used. This was discovered due
to a bug fix in the /sbin/tc utility found in iproute-3.11.0.1 (on f20)
in which overflow was actually caught and returned as an error. The fix
was first introduced in iproute-3.10 (search on iproute2 commit 'a303853e').

The autotest/virt-test test for virsh domiftune was attempting to send
the largest unsigned integer value (4294967295) for maximum value
testing. The libvirt xml implementation was designed to manage values
in kilobytes thus when this value was passed to /sbin/tc, it (now)
properly rejected the 4294967295kbps value.

Investigation of the problem discovered that formatdomain.html.in and
formatnetwork.html.in described the elements and property types slightly
differently, although they use the same code - virNetDevBandwidthParseRate()
(shared by portgroups, domains, and networks xml parsers). Rather than
have the descriptions in two places, this patch will combine and reword
the description under formatnetwork.html.in and have formatdomain.html.in
link to that description.

This documentation faux pas was continued into the virsh man page where
the bandwidth description for both 'attach-interface' and 'domiftune'
did not indicate the format of each value, thus leading to the test using
largest unsigned integer value assuming "bps" rather than "kbps", which
ultimately was wrong.

And provide domain summary stat in that case, for lxc backend.
Use case is a container inheriting all devices from the host,
e.g. when doing application containerization.

Mark the shm-merge-across-nodes parameter of node-memory-tune command
as optional in the virsh man page.

For pool which relies on remote resources, such as a "iscsi" type
pool, since how long it takes to export the corresponding devices
to host's sysfs is really depended, it could depend on the network
connection, it also could depend on the host's udev procedures. So
it's likely that the volumes are not able to be detected during pool
starting process, polling the sysfs doesn't work, since we don't
know how much time is best for the polling, and even worse, the
volumes could still be not detected or partly not detected even after
the polling.  So we end up with a documentation to prompt the fact,
in virsh manual.

And as a small improvement, let's explicitly say no LUNs found in
the debug log in that case.

To let the user know the command onlys work for KSM under Linux.

Explicitly lists the possible values for "--target" option;
Gets rid of the confused strings like "Suspend-to-RAM";
Emphasises the node *has to* be suspended in the time duration
specified by "--duration". And rewords the entire document a
bit according to the API's implementation and document.

With this patch, user can setup the throttle blkio cgorup
for domain through the virsh cmd, such as:

virsh blkiotune domain1 --device-read-bytes-sec /dev/sda1,1000000,/dev/sda2,2000000
--device-write-bytes-sec /dev/sda1,1000000 --device-read-iops-sec /dev/sda1,10000
--device-write-iops-sec /dev/sda1,10000,/dev/sda2,0

Recent addition of the gluster pool type omitted fixing the virsh and
virConnectListAllStoragePool filters. A typecast of the converting
function in virsh showed that also the sheepdog pool was omitted in the
command parser.

This patch adds gluster pool filtering support and fixes virsh to
properly convert all supported storage pool types. The added typecast
should avoid doing such mistakes in the future.

Commit d923f6c8 introduced the --driver option but didn't document it in
the man page. The docs are borrowed from the public API documentation.

The parameter specifies connection parameters to use for migrating
client's connection to domain's graphical console.

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.

Document for nodedev-list is also updated.

This patch fixes changes done in commit 29c1e913
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.
