0eced74f34 vz: implement managed migration
The newest version of migration protocol - version 3 with parameters is implemented.
Supported flags is VIR_MIGRATE_PAUSED only. Supported parameters are
VIR_MIGRATE_PARAM_URI and VIR_MIGRATE_PARAM_DEST_NAME. VIR_MIGRATE_PARAM_DEST_XML
is in VZ_MIGRATION_PARAMETERS for technical onyl reasons.

abc85b2cab vz: add domain snapshots functionality
This solution does not keep snapshots cache because vz sdk lacks good support
for snapshot related events.

Libvirt and vz sdk has different approach to snapshot ids. vz sdk always
auto generate them while libvirt has ability to specify id by user.
Thus I have no other choice rather than simply ignore ids set by user
or generated by libvirt.

7762c5a233 vz: introduce new vzDriver lockable structure and use it
This patch introduces a new 'vzDriver' lockable object and provides
helper functions to allocate/destroy it and we pass it to prlsdkXxx
functions instead of virConnectPtr.
Now we store domain related objects such as domain list, capabitilies
etc. within a single vz_driver vzDriver structure, which is shared by
all driver connections. It is allocated during daemon initialization or
in a lazy manner when a new connection to 'vz' driver is established.
When a connection to vz daemon drops, vzDestroyConnection is called,
which in turn relays disconnect event to all connection to 'vz' driver.

ad584cbb6c vz: implement memory setting functions
Quite straigthforward as vz sdk memory setting function makes
just what we want to that is set "amount of physical memory
allocated to a domain".

'useflags' is introduced for non flag function implementation.
We can't just use combination of flags like "live | config" or
we fail for inactive domains. Other combinations have drawbacks
too.

bb2f63da79 vz: set default SCSI model
Each version of virtuozzo supports only one type of SCSI controller
So if we add disk on SCSI bus, we should set SCSI controller model.
We can take it from vzCapabilities structure.

9c14a9ab42 vz: fix race condition when adding domain to domains list
Race condition:
User calls defineXML to create new instance.
The main thread from vzDomainDefineXMLFlags() creates new instance by prlsdkCreateVm.
Then this thread calls prlsdkAddDomain to add new domain to domains list.
The second thread receives notification from hypervisor that new VM was created.
It calls prlsdkHandleVmAddedEvent() and also tries to add new domain to domains list.
These two threads call virDomainObjListFindByUUID() from prlsdkAddDomain() and don't find new domain.
So they add two domains with the same uuid to domains list.

This fix splits logic of prlsdkAddDomain() into two functions.
1. vzNewDomain() creates new empty domain in domains list with the specific uuid.
2. prlsdkLoadDomain() add data from VM to domain object.

New algorithm for creating an instance:
In vzDomainDefineXMLFlags() we add new domain to domain list by calling vzNewDomain()
and only after that we call CreateVm() to create VM.
It means that we "reserve" domain object with the specific uuid.
After creation of new VM we add info from this VM
to reserved domain object by calling prlsdkLoadDomain().

Before this patch prlsdkLoadDomain() worked in 2 different cases:
1. It creates and initializes new domain. Then updates it from sdk handle.
2. It updates existed domain from sdk handle.
In this patch we remove code which creates new domain from LoadDomain()
and move it to vzNewDomain().
Now prlsdkLoadDomain() only updates domain from skd handle.

In notification handler prlsdkHandleVmAddedEvent() we check
the existence of a domain and if it doesn't exist we add new domain by calling
vzNewDomain() and load info from sdk handle via prlsdkLoadDomain().

bb7d275d15 vz: add memory statistics
Implemented counters:
 VIR_DOMAIN_MEMORY_STAT_SWAP_IN
 VIR_DOMAIN_MEMORY_STAT_SWAP_OUT
 VIR_DOMAIN_MEMORY_STAT_MINOR_FAULT
 VIR_DOMAIN_MEMORY_STAT_MAJOR_FAULT
 VIR_DOMAIN_MEMORY_STAT_AVAILABLE
 VIR_DOMAIN_MEMORY_STAT_ACTUAL_BALLOON
 VIR_DOMAIN_MEMORY_STAT_UNUSED

Comments.

1. Use vzDomObjFromDomainRef/virDomainObjEndAPI pair to get domain
object as we use prlsdkGetStatsParam. See previous statistics
comments.

2. Balloon statistics is not applicable to containers. Fault
statistics for containers not provided in PCS6 yet.

Comments.

Use vzDomObjFromDomainRef/virDomainObjEndAPI pair to get domain
object as we use prlsdkGetStatsParam that can release domain
object lock and thus we need a reference in case domain
is deleated meanwhile.

In the e6d180f07f commit the parallels driver was renamed to vz.
However, there was a commit merged later, which was sent to the list
before the rename. The other commit is 6de12b026b. Fix all the
missing renames.

6de12b026b vz: implementation of attach/detach network devices
In this patch we add VIR_DOMAIN_DEVICE_NET handlers implementation
for domainAttachDevice and domainDetachDevice callbacks.

As soon as we don't support this operation for hypervisor type domains,
we implement this functionality for containers only.

In detach procedure we find network device by MAC address.
Because PrlVmDevNet_GetMacAddress() returns MAC as a UTF-8 encoded
null-terminated string, we use memcmp() to compare it.
Also we remove corresponding virtual network by prlsdkDelNetAdapter call.
