[libvirt] [PATCH v2] add func to set shared drivers after libvirtd init
Diff from v1:
Remove vz prefix from the title of this letter. Because this is the common case
for all drivers in libvirt.
Description:
Built-in drivers in libvirt are initialized before libvirtd initialization.
Libvirt loads shared drivers on libvirtd initialization step.
For built-in drivers we can't set shared drivers, because they are not initialized
yet.
This patch adds function to set shared drivers after libvirtd init.
