There are no storage pools in Parallels Cloud Server -
All VM data stored in a single directory: config, snapshots,
memory dump together with disk images.
Let's look through list of VMs and create a storage pool for
each directory, containing VMs.
So if you have 3 vms: /var/parallels/vm-1.pvm,
/var/parallels/vm-2.pvm and /root/test.pvm - 2 storage pools
appear: -var-parallels and -root. xml descriptions of the pools
will be saved in /etc/libvirt/parallels-storage, so UUIDs will
not change netween connections to libvirt.

We don't support unprivileged users anymore, so remove code, which
selects configuration directory depending on user.

The virStateInitialize method and several cgroups methods were
using an 'int privileged' parameter or similar for dual-state
values. These are better represented with the bool type.

This will simplify the refactoring of the ESX storage driver to support
a VMFS and an iSCSI backend.
One of the tasks the storage driver needs to do is to decide which backend
driver needs to be invoked for a given request. This approach extends
virStoragePool and virStorageVol to store extra parameters:
1. privateData: stores pointer to respective backend storage driver.
2. privateDataFreeFunc: stores cleanup function pointer.
virGetStoragePool and virGetStorageVol are modfied to accept these extra
parameters as user params. virStoragePoolDispose and virStorageVolDispose
checks for cleanup operation if available.
The private data pointer allows the ESX storage driver to store a pointer
to the used backend with each storage pool and volume. This avoids the need
to detect the correct backend in each storage driver function call.
In the XML warning, we print a virsh command line that can be used to
edit that XML. This patch prints UUIDs if the entity name contains
special characters (like shell metacharacters, or "--" that would break
parsing of the XML comment). If the entity doesn't have a UUID, just
print the virsh command that can be used to edit it.
Found this when building on RHEL5:
parallels/parallels_storage.c: In function 'parallelsStorageOpen':
parallels/parallels_storage.c:180: error: 'for' loop initial declaration used outside C99 mode
(and similar error in parallels_driver.c). This was in spite of
configuring with "-Wno-error".
https://www.gnu.org/licenses/gpl-howto.html recommends that
the 'If not, see <url>.' phrase be a separate sentence.
* tests/securityselinuxhelper.c: Remove doubled line.
* tests/securityselinuxtest.c: Likewise.
* globally: s/; If/. If/
To create a new VM in Parallels Clud Server we should issue
"prlctl create" command, and give path to the directory,
where VM should be created. VM's storage will be in that
directory later. So in this first version find out location
of first VM's hard disk and create VM there.

Parallels Cloud Server has one serious discrepancy with libvirt:
libvirt stores domain configuration files in one place, and storage
files in other places (with the API of storage pools and storage volumes).
Parallels Cloud Server stores all domain data in a single directory,
for example, you may have domain with name fedora-15, which will be
located in '/var/parallels/fedora-15.pvm', and it's hard disk image will be
in '/var/parallels/fedora-15.pvm/harddisk1.hdd'.
I've decided to create storage driver, which produces pseudo-volumes
(xml files with volume description), and they will be 'converted' to
real disk images after attaching to a VM.
So if someone creates VM with one hard disk using virt-manager,
at first virt-manager creates a new volume, and then defines a
domain. We can lookup a volume by path in XML domain definition
and find out location of new domain and size of its hard disk.
