As it turned out PrlVmDev_GetStackIndex can return negative values
without reporting an error, which is incorrect but nevertheless.
After that we feed this negative index to virIndexToDiskName,
which in turn returns NULL and we set it to virDomainDiskDef.dst.
Using virDiskNameToBusDeviceIndex with a virDomainDiskDef structure
which has NULL dst field crashes.

in times when every vz libvirt connections spawns its own sdk connection.

Linux-specific, when the APIs are intended to be cross

This removes the sysfs_prefix parameter and instead gives
a new method linuxNodeInfoSetSysFSSystemPath for use by

For two of the methods this hardcodes use of the constant
SYSFS_SYSTEM_PATH, since the test suite does not need to
override the path for thos methods.

As usual we try to deal correctly with vz domains that were
created by other means and thus can have all range of SDK domain
parameters. If vz domain boot order can't be represented
in libvirt os boot section let's give warning and make os boot section
represent SDK to some extent.
1. Os boot section supports up to 4 boot devices. Here we just
cut SDK boot order up to this limit. Not too bad.
2. If there is a floppy in boot order let's just skip it.
Anyway we don't show it in the xml. Not too bad too.
3. SDK boot order with unsupported disks order. Say we have "hdb, hda" in
SDK. We can not present this thru os boot order. Well let's just
give warning but leave double <boot dev='hd'/> in xml. It's
kind of misleading but we warn you!
SDK boot order have an extra parameters 'inUse' and 'sequenceIndex'
which makes our task more complicated. In realitly however 'inUse'
is always on and 'sequenceIndex' is not less than 'boot position index'
which simplifies out task back again! To be on a safe side let's explicitly
check for this conditions!
We have another exercise here. We want to check for unrepresentable
condition 3 (see above). The tricky part is that in contrast to
domains defined thru this driver 3-rd party defined domains can
have device ordering different from default. Thus we need
some id to check that N-th boot disk of os boot section is same as
N-th boot disk of SDK boot. This is what prlsdkBootOrderCheck
for. It uses disks sources paths as id for disks and iface names
for network devices.

The patch makes some refactoring of the existing code. Current boot order spec code
makes very simple thing in somewhat obscure way. In case of VMs
it sets the first hdd as the only bootable device. In case of CTs it
doesn't touch the boot order at all if one of the filesystems is mounted to root.
Otherwise like in case of VMs it sets the first hdd as the only bootable
device and additionally sets this device mount point to root. Refactored
code makes all this explicit.
The actual boot order support is simple. Common libvirt domain xml parsing
code makes the exact ordering of disks devices as described in docs
for boot ordering (disks are sorted by bus order first, device target
second. Bus order is the order of disk buses appearence in original
xml. Device targets order is alphabetical). We add devices in the
same order and SDK designates device indexes sequentially for each
device type. Thus device index is equal to its boot index. For
example N-th cdrom in boot specification refers to sdk cdrom with
it's device index N.
If there is no boot spec in xml the parsing code will add <boot dev='hdd'>
for HVMs automatically and we backward compatibly set fist hdd as
bootable.

Introduce a helper to check supported device and domain config and move
the memory hotplug checks to it.
The advantage of this approach is that by default all new features are
considered unsupported by all hypervisors unless specifically changed
rather than the previous approach where every hypervisor would need to
declare that a given feature is unsupported.
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().
Bug cause:
Update the domain that is subscribed to hypervisor notification.
LoadDomain() rewrites notifications fields in vzDomObj structure and makes domain as "unsubscribed".
Fix:
Initialize notification fields in vzDomObj only if we create a new domain.
And do not reinitialize these fields if we update domain (by calling LoadDomain with olddom argument)
prlsdkGetDomainIds() returns name and uuid for specified instance.
Now output arguments can be NULL.
It allows to get only necessary info(name or uuid).
And use the newly added caps->host.netprefix (if it exists) for
interface names that match the autogenerated target names.

Currently vz driver unregisters domains when undefine is called,

All vz domains are persistent, which means that when one is

Undefining domains in a way we do now leaves those directories
undeleted, which prevents subsequent define call for the same
domain xml. I.e. the following sequence define->undefine->define
doesn't work now.

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.

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.
There was many errors in libvirt.log caused by prlsdkDelNet function because
job variable was always initialized as PRL_INVALID_HANDLE
In this patch job variable gets return value of PrlSrv_DeleteVirtualNetwork function()
This patch moves all src/parallels/parallels* files to vz/vz*
and fixes build accordingly.
No functional changes.
