In case of real migration (not migrating to file on save, dump etc)
migration info is not complete at time qemu finishes migration
in normal (non postcopy) mode. We need to update disks stats,
downtime info etc. Thus let's not expose this job status as
completed.
To archive this let's set status to 'qemu completed' after
qemu reports migration is finished. It is not visible as complete
job to clients. Cookie code on confirm phase will finally turn
job into completed. As we don't need more things to do when
migrating to file status is set to 'completed' as before
in this case.

Setting status to none has little value - getting job status
will not return even elapsed time.
After this patch getting job stats stays correct in a sence

Querying destination migration statistics may result in getting
a failure or getting a elapsed time value depending on stats.status
value which is odd. Instead let's always fail. Clients should
be ready to handle this as currently getting failure period
can be considerable.

qemuMigrationFetchJobStatus is rather inconvinient. Some of its
callers don't need status to be updated, some don't need to update
elapsed time right away. So let's update status or elapsed time
in callers instead.
This patch drops updating job status on getting job stats by
client. This way we will not provide status 'completed' while
it is not yet updated by migration routine.
Signed-off-by: Jiri Denemark <jdenemar@redhat.com>
This way we get stats only in one place. The former code waits for
complete/postcopy status basically and don't need to mess with stats.
The patch drops raising an error on stats updates failure. This
does not make much sense anyway.

Let's introduce QEMU_DOMAIN_JOB_STATUS_POSTCOPY state for job.current->status
instead of checking job.current->stats.status. The latter can be changed
when fetching migration statistics. Moving state function from the variable
and leave only store function seems more managable.
This patch removes all state checking usage of stats except for
qemuDomainGetJobStatsInternal. This place will be handled separately.

Whenever a device is being updated via
virDomainUpdateDeviceFlags() API, we parse the device XML and
ideally run some generic checks to validate the configuration
(e.g. if device defines per-device boot order but the domain has
os/boot element already). Well, that's the theory - due to a
missing check we've jumped early from that check function.

Neither @cfg nor (now) @driver is used in the API, so remove them
and mark @opaque as UNUSED.
NB: Commit id 'fa3c558596' dropped the unused @qemuCaps which was the
last consumer of @driver other than @cfg, but even @cfg was never used
even in the original implementation from commit id 'd987f63a'.
arm/aarch64 -M virt on KVM doesn't and will never work with standard

Although not previously explicitly documented, the expectation for
the libvirt event loop is that an implementation is registered early
in application startup, before calling any libvirt APIs and then
run forever after. Replacing a previously registered event loop is
not safe & subject to races even if virConnectClose has been called
on open handles, due to delayed deregistration of callbacks during
conenction close.

Funny thing. So when initializing LXC driver's capabilities,
firstly the virLXCDriverGetCapabilities() is called. This creates
new capabilities, stores them under driver->caps, ref() them and
return them. However, the return value is ignored. Secondly, the
function is called yet again and since we have driver->caps set,
they are ref()-ed again an returned. So in the end, driver's
capabilities have refcount of three when in fact they should have
refcount of one.

If you use the VDDK library to access virtual machines remotely, you
really need to know the Managed Object Reference ("moref") of the VM.
This must be passed each time you connect to the API.
For example nbdkit's VDDK plugin requires a moref to be passed to
mount up a VM's disk remotely:
nbdkit vddk user=root password=+/tmp/rootpw \
server=esxi.example.com thumbprint=xx:xx:xx:... \
vm=moref=2 \
file="[datastore1] Fedora/Fedora.vmdk"
Getting the moref is a huge pain. To get some idea of what it is, why
it is needed, and how much trouble it is to get it, see:
https://blogs.vmware.com/vsphere/2012/02/uniquely-identifying-virtual-machines-in-vsphere-and-vcloud-part-1-overview.htmlhttps://blogs.vmware.com/vsphere/2012/02/uniquely-identifying-virtual-machines-in-vsphere-and-vcloud-part-2-technical.html
However the moref is available conveniently in the internals of the
libvirt VMX driver. This patch exposes it as a custom XML element
using the same "vmware:" namespace which was previously used for the
datacenterpath (see libvirt commit 636a990587).
It appears in the XML like this:
<domain type='vmware' xmlns:vmware='http://libvirt.org/schemas/domain/vmware/1.0'>
<name>Fedora</name>
...
<vmware:datacenterpath>ha-datacenter</vmware:datacenterpath>
<vmware:moref>2</vmware:moref>
</domain>
Note that the moref can appear as either a simple ID (for esx://
connections) or as a "vm-<ID>" (for vpx:// connections). It should be
treated by users as an opaque string.

Rather than using refreshVol which essentially only updates the
allocation, capacity, and permissions for the volume, but not
the format which does get updated in a pool refresh - let's use
the same helper that pool refresh uses in order to update the
volume target.
Currently while parsing domain XML we clear the UNIX path if it matches
one of the auto-generated paths by libvirt. After that when the guest
is started new path is generated but the mode is also changed to "bind".
In the real-world use-case the mode should not change, it only happens
if a user provides a mode='connect' and path that matches one of the
auto-generated path or not provides a path at all.
Before *reconnect* feature was introduced there was no issue, but with
the new feature we need to make sure that it's used only with "connect"
mode, therefore we need to move the mode change into parsing in order
to have a proper error reported by validation code.
