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.

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.

client. This way we will not provide status 'completed' while
it is not yet updated by migration routine.

Let's introduce QEMU_DOMAIN_JOB_STATUS_POSTCOPY state for job.current->status

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 'fa3c5585' 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
VGA card emulation. The recommended method is to use type=virtio, so

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

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.html
https://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 636a9905).

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.
