When libvirt is starting a domain, it reports the state as SHUTOFF until
it's RUNNING. This is not ideal because domain startup may take a long
time (usually because of some configuration issues, firewalls blocking
access to network disks, etc.) and domain lists provided by libvirt look
awkward. One can see weird shutoff domains with IDs in a list of active
domains or even shutoff transient domains. In any case, it looks more
like a bug in libvirt than a normal state a domain goes through.

The command did not modify the disk type and thus didn't allow to change
media from a file image to a block backed image or vice versa. In
addition when operating on a network backed removable devices the
command would replace the while <source> subelement with an invalid one.
This patch adds the --block option that allows to specify that the new
image is block backed and assumes that without that option all images
are file backed. Since network backends were always mangled it should
not cause problems.
Since cmdDetachDisk() calls into vshPrepareDiskXML() with
type == VSH_PREPARE_DISK_XML_NONE && source == NULL this would result
into skipping all the checks and effectively turn the function into a
XML formatter.
This patch changes the code to use the formatter directly so that the
function can be refactored in a easier way.

Well, imagine domains were running, and as the host went down, they
were managesaved. Later, after some time, the host went up again and
domains got restored. But without correct time. And depending on how
long was the host shut off, it may take some time for ntp to sync the
time too. But hey, wait a minute. We have an API just for that! So:
1) Introduce SYNC_TIME variable in libvirt-guests.sysconf to allow
users control over the new functionality
2) Call 'virsh domtime --sync $dom' in the libvirt-guests script.
Unfortunately, this is all-or-nothing approach (just like anything
else with the script). Domains are required to have configured and

virsh's domdisplay command looks in /domain/devices/graphics/@listen
of the domain's XML for the listen address, however for listen
type='network' (added in libvirt 0.9.4), the <graphics> element
doesn't have a listen attribute, but has a <listen> subelement,
*still* with no address (this is the inactive XML):
<graphics type='spice' autoport='yes' keymap='en-us'>
<listen type='network' network='default'/>
</graphics>
However, at domain start time the <listen> subelement gets its address
attribute filled in once libvirt figures out the IP address associated
with the named network (this is the status XML):
<graphics type='spice' port='5901' autoport='yes' keymap='en-us'>
<listen type='network' address='192.168.122.1' network='default'/>
</graphics>
So in these cases, we need to look at
/domain/devices/graphics/listen/@address instead.
Even though another patch is being pushed that will backfill
listen/@address into @listen, this patch is still useful, as it fixes
domdisplay for cases of a new virsh (with this patch) connecting to a
libvirtd that is newer than 0.9.4 but doesn't have the followup patch.

This patch introduces access to allocation information about
a backing chain of a live domain. While querying storage
volumes for read-only disks could provide some of the details,
we do NOT want to read() a file while qemu is writing it.
Also, there is one case where we have to rely on qemu: when
doing a block commit into a backing file, where that file is
stored in qcow2 format on a host block device, we want to know
the current highest write offset into that image, in order to
know if the disk must be resized larger. qemu-img does not
(currently) show this information, and none of the earlier
block APIs were extensible enough to expose it. But
virDomainListGetStats is perfect for the job!
We don't need a new group of statistics, as the existing block
group is sufficient. On the other hand, as existing libvirt
releases already report 1:1 mapping of block.count to <disk>
devices, changing the array size could confuse older clients;
and even with newer clients, the time and memory taken to
report additional statistics is not always necessary (backing
files are generally read-only except for block-commit, so while
read statistics may change, sizing statistics will not). So
the choice here is to add a new flag that only newer callers
will pass, when they are prepared for the additional information.
This patch introduces the new API, but it will take more
patches to get it implemented for qemu.

(VIR_CONNECT_GET_ALL_DOMAINS_STATS_BACKING): New flag.

I'm about to make block stats optionally more complex to cover

may decide to add that later.

This new event will use typedParameters to expose what has been actually
updated and the reason is that we can in the future extend any tunable
values or add new tunable values. With typedParameters we don't have to
worry about creating some other events, we will just use this universal
event to inform user about updates.

RDMA Live migration requires registering memory with the hardware, and
thus QEMU offers a new 'capability' to pre-register / mlock() the guest
memory in advance for higher RDMA performance before the migration
begins. This capability is disabled by default, which means QEMU will
register the memory with the hardware in an on-demand basis.
This patch exposes this capability with the following example usage:
virsh migrate --live --rdma-pin-all --migrateuri rdma://hostname domain qemu+ssh://hostname/system

RDMA migration uses the 'setup' state in QEMU to optionally lock
all memory before the migration starts. The total time spent in
this state is exposed as VIR_DOMAIN_JOB_SETUP_TIME.
Additionally, QEMU also exports migration throughput (mbps) for both
memory and disk, so let's add them too: VIR_DOMAIN_JOB_MEMORY_BPS,
VIR_DOMAIN_JOB_DISK_BPS.

Add an iothread parameter to allow attaching to an IOThread, such as:
virsh attach-disk $dom $source $target --live --config --iothread 2 \
--targetbus virtio --driver qemu --subdriver raw --type disk
Coverity complained that checking the return of virDomainCreate()
was not consistent amongst the callers - so added the return check
to the objecteventtest.c and adjust the virt-login-shell to compare
< 0 rather than just non zero for the failure condition.
Coverity complains that on the first pass through the for loop that
'params' cannot be true, thus the ternary setting to "&" cannot be
done. Since we can only ever get to this point once, drop the ternary
When a domain is undefined, there are options to remove it's
managed save state or snapshots. However, there's another file
that libvirt creates per domain: the NVRAM variable store file.
Make sure that the file is not left behind if the domain is
undefined.
