[libvirt] [PATCH] set UID and GID according to dynamicOwnership

[Matteo Cafasso]

When called with dynamicOwnership set, the qemuOpenFileAs function ignores it resulting in files not created with proper permissions.

The issue is reported in:

https://www.redhat.com/archives/libvirt-users/2015-November/msg00039.html

and also mentioned in:
