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.
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.

VIR_STORAGE_FILE_AUTO should be used only in xml provided to
libvirt by user, if I understood correctly. Driver should
set storage source format to specific disk format in

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'.

First, we don't need to call prlsdkApplyConfig after
creating new VM or containers, because it's done in
functions prlsdkCreateVm and prlsdkCreateCt.
No need to check, if domain exists in the list after
prlsdkAddDomain.
Also organize code, so that we can call virObjectUnlock
in one place.

This patch replaces code, which creates domains by
running prlctl command.
prlsdkCreateVm/Ct will do prlsdkApplyConfig, because
we send request to the server only once in this case.
But prlsdkApplyConfig will be called also from
parallelsDomainDefineXML function. There is no problem with
it, parallelsDomainDefineXML will be refactored later.

Rewrite code, which applies domain configuration given
to virDomainDefineXML function to the VM of container
registered in PCS.
This code first check if there are unsupported parameters
in domain XML and if yes - reports error. Some of such
parameters are not supported by PCS, for some - it's not
obvious, how to convert them into PCS's corresponding params,
so let's put off it, and implement only basic params in
this patch.

Subscribe to events from parallels server. It's
needed for 2 things: to update cached domains list
and to send corresponding libvirt events.

configuration or devices states.

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.
