[libvirt] [PATCH] 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.
