Since commit a4cda054e7 we are using 'ide-hd' and 'ide-cd' instead of
'ide-drive'. We also should probe capabilities for 'ide-hd' instead of
'ide-drive'. It is safe to do as 'ide-drive' is the common denominator
of both 'ide-hd' and 'ide-cd' so all the properties were common.
For now the test data are modified by just changing the appropriate type
when probing for caps.

Some migration parameters supported by libvirt may use units that differ
from the units used by QEMU for the corresponding parameters. For
example, libvirt defines migration bandwidth in MiB/s while QEMU expects
B/s. Let's add a unit field to qemuMigrationParamsTPMapItem for
automatic conversion when translating between libvirt's migration typed
parameters and QEMU's migration paramteres.
This patch is a preparation for future parameters as the existing
VIR_MIGRATE_PARAM_BANDWIDTH parameter is set using "migrate_set_speed"
QMP command rather than "migrate-set-parameters" for backward
compatibility.

The writing to an image actually starts when the copy job is initiated,
so checking this at the time of the pivot operation is too late.
Move the check to qemuDomainBlockCopyCommon. Note that modern qemu would
have prevented two writers with qcow2 so the slim possibility of a job
started with libvirtd without this patch missing the check is not really

If the container is really a simple one (init is just bash and
the whole root is passed through) then virDomainReboot and
virDomainShutdown will talk to the actual init within the host.
Therefore, 'virsh shutdown $dom' will result in shutting down the
host. True, at that point the container is shut down too but
looks a bit harsh to me.
The solution is to check if the init inside the container is or
is not the same as the init running on the host.

So far the virInitctlSetRunLevel() is fully automatic. It finds
the correct fifo to use to talk to the init and it will set the
desired runlevel. Well, callers (so far there is just one) will
need to inspect the fifo a bit just before the runlevel is set.
Therefore, expose the internal list of fifos and also allow
caller to explicitly use one.

In commit f80eae8c2a I was too agresive in removing properties of

state of 'readonly' and the throttling information even for the empty
drive.
Removing 'readonly' thus made qemu open any subsequent images added via
the 'change' command as RW which was forbidden by selinux thanks to the
restrictive sVirt label for readonly media.
Fix this by formating the property again and bump the tests and leave a
note detailing why the rest of the properties needs to be skipped.
