[PATCH v6 4/4] qemu: Implement rbd namespace to the source name attribute

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

 



Since Nautilus ceph supports separate image namespaces within a pool for
tenant isolation and QEMU adds it as a rbd blockdev options from 5.0.0.
The source name with format "<pool>/<namespace>/<image>" could be used to
access a rbd image with namespace.

Add unit tests for this attribute.
