Cleanup code in prlsdkLoadDomain doesn't take into account the fact
if private domain structure along with freeing function is assigned
or not. In case it is, we shouldn't call it manually because
virDomainObjListRemove calls it and frees pdom.
Also, allocated def structure should be freed only if it's not
assigned to domain. Otherwise it will be called twice: one time by
virDomainObjListRemove and the second by prlsdkLoadDomain itself.

So far, we are not reporting if numatune was even defined. The
value of zero is blindly returned (which maps onto
VIR_DOMAIN_NUMATUNE_MEM_STRICT). Unfortunately, we are making
decisions based on this value. Instead, we should not only return
the correct value, but report to the caller if the value is valid
at all.
For better viewing of this patch use '-w'.

We have a lot of passing arguments code just to pass connection
object cause it holds jobTimeout. Taking into account that
right now this value is defined at compile time let's just
get rid of it and make arguments list more clear in many
places.
In case we later need some runtime configurable timeout
value we can provide this value through arguments
function already operate such as a parallels domain
object etc as this timeouts are operation( and thus
object) specific in practice.

In Parallels we do not support device name hints
aka <target dev=../> option and full-fledged device
disk device addressing through
<address type=.. controller=.. bus=.. target=.. unit=../>
and have only one index instead.
In this situation to be consistent we can only take
one-to-one mapping from some reasonable subset
of full address. Values outside this subset are
invalid to create Parallels VMs.
Reasonable mapping is default one defined in virDomainDiskDefAssignAddress.

OpenStack needs disk serial number setup because
nova boot --block-device-mapping command generates that param in
libvirt xml. I took QEMU libvirt driver behavior as a base.
QEMU driver skips inability to set serial and continues work.
So Parallels driver will ignore this param too and let domain
boot.
We support VNC for containers to have the same
interface with VMs. At this moment it just renders
linux text console.
Of course we don't pass any physical devices and
don't emulate virtual devices. Our VNC server
renders text from terminal master and sends
input events from VNC client to terminal.
So add special video type VIR_DOMAIN_VIDEO_TYPE_PARALLELS
for these pseudo-devices.

In order to change an existing domain we delete all existing devices and add
new from scratch. In case of network devices we should also delete corresponding
virtual networks (if any) before removing actual devices from xml. In the patch,
we do it by extending prlsdkDoApplyConfig with a new parameter, which stands for
old xml, and calling prlsdkDelNet every time old xml is specified.

In order to support 'bridge' network adapters in parallels
driver we need to plug our veth devices into corresponding
linux bridges.
We are going to do this by reusing our abstraction of
Virtual Networks in terms of PCS. On a domain creation, we
create a new Virtual Network naming it with the same name
as a source bridge for each network interface.
Having done this, we plug PCS veth interfaces created with names of
target dev into specified bridges using our standard PCS procedures

Otherwise exporting existing domain config and defining a new one like this:

virsh -c parallels:///system define my.xml

As there are two possible approaches to define a domain's memory size -
one used with legacy, non-NUMA VMs configured in the <memory> element
and per-node based approach on NUMA machines - the user needs to make
sure that both are specified correctly in the NUMA case.
To avoid this burden on the user I'd like to replace the NUMA case with
automatic totaling of the memory size. To achieve this I need to replace
direct access to the virDomainMemtune's 'max_balloon' field with
two separate getters depending on the desired size.
The two sizes are needed as:
1) Startup memory size doesn't include memory modules in some
hypervisors.
2) After startup these count as the usable memory size.
Note that the comments for the functions are future aware and document
state that will be present after a few later patches.
1. Delete all boot devices for VM instance
2. Find the first HDD from XML and set it as bootable
Now we support only one boot device and it should be HDD.

It's possible to create a container with existing
disk image as root filesystem. You need to remove
existing disks from PCS VM config and then add a new
one, pointing to your image. And then call PrlVm_RegEx
with PRNVM_PRESERVE_DISK flag.
With this patch you can create such container with
something like this for new domain XML config:
<filesystem type='file' accessmode='passthrough'>
<driver type='ploop' format='ploop'/>
<source file='/path-to-image'/>
<target dir='/'/>
</filesystem>

For SCSI and SATA devices controller and unit are used
to specify drive address. For IDE devices - bus specifies
IDE bus, becase usually there are 2 IDE buses on IDE
controller.
Parallels SDK allows to set drive position by calling
PrlVmDev_SetStackIndex. Since PCS VMs have only one
controller of each type, for SATA and SCSI devices it
simple means position on bus, for IDE devices -
2 * bus_number + position_on_bus.
This patch fixes mapping from libvirt's disk->info.addr.drive
to parallels's 'StackIndex'.
