[PATCH v2] add func to set shared drivers after libvirtd init

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
