We should do this because this feature can't be controlled
by libvirt now and it sets up some iptables rules. So it's
better to do this to avoid potential conflict of different
set of rules or to avoid unexpected behavior.

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 dumpxml instance01 > my.xml
virsh -c parallels:///system define my.xml
leads to an error because PCS default x64 mode turns to x32.
Thus, we need to set correct cpuMode in prlsdkDoApplyConfig() explicitly.

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.

Use the virDomainDefNew() helper to allocate the definition instead of
doing it via VIR_ALLOC.

The structure will gradually become the only place for NUMA related
config, thus rename it appropriately.

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>

PCS removes disk image from filesystem, if you remove it
from config. There is a special flag PVCF_DETACH_HDD_BUNDLE
which allow to remove disk only from VM/CT config.

If you call virDomainDefine and remove some disk from
config it should be preserved, so call PrlVm_CommitEx
always with flag PVCF_DETACH_HDD_BUNDLE.

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'.

This code first check if there are unsupported parameters
in domain XML and if yes - reports error. Some of such

obvious, how to convert them into PCS's corresponding params,
so let's put off it, and implement only basic params in

Add files parallels_sdk.c and parallels_sdk.h for code
which works with SDK, so libvirt's code will not mix with
dealing with parallels SDK.

To use Parallels SDK you must first call PrlApi_InitEx function,
and then you will be able to connect to a server with
PrlSrv_LoginLocalEx function. When you've done you must call
PrlApi_Deinit. So let's call PrlApi_InitEx on first .connectOpen,
count number of connections and deinitialize, when this counter
becomes zero.
