New subject: [libvirt] [PATCH 1/3 v2] vz: allow to create container based on template
We shouldn't delete disk from default config if we create container based on
template,
because we don't have the new disk from XML, only template name.
And don't add template section from XML as new filesystem,
we use PrlVmCfg_SetOsTemplate function to set template name.
Do not set PRNVM_PRESERVE_DISK flag in PrlVm_RegEx() call,
because this will cause an error during CT startup.

diff from v1:
Remove unusable variable (PRL_VM_DEV_EMULATION_TYPE emul)
Add parameter useCtTemplateFs in prlsdkDoApplyConfig() function
Allow only one fs with "template" type and only for CT creation

New subject: [libvirt] [PATCH 2/3 v2] vz: allow to boot VM from cdrom
If user creates virtual machine via virt-manager and select "boot from ISO"
then in libvirt we can see the following devices section
<disk type="file" device="disk">
<source file="/var/lib/libvirt/images/generic.img"/>
<target dev="hda" bus="ide"/>
</disk>
<disk type="file" device="cdrom">
<source
file="/var/lib/libvirt/images/Fedora-Live-Xfce-x86_64-23-10.iso"/>
<target dev="hdb" bus="ide"/>
<readonly/>
</disk>
These devices don't have disk->format parameter, so we should
allow to add disks with format = VIR_STORAGE_FILE_NONE.
If user select boot from HDD and add new Cdrom device then we see
<disk type="file" device="cdrom">
<target dev="hdb" bus="ide"/>
<readonly/>
</disk>
Cdrom device doesn't have disk->source parameter,
it means that user did select "attach to real device" or "use ISO".
So we should not return error if we get device with empty source path.

New subject: [libvirt] [PATCH 3/3 v2] vz: implementation of boot device order
This patch implements functionality of boot device order
based on boot element from os section in XML.
Now we support boot from CDROM and HDD.
If we have several devices of the same type (for example hdd0 and hdd1),
than we mark the first one as bootable.
