RHBA-2015:0646 - Bug Fix Advisory

Topic

Updated libvirt-python packages that fix one bug are now available for Red Hat
Enterprise Linux 7.

Description

The libvirt-python packages contain a module that permits applications written
in the Python programming language to use the interface supplied by the libvirt
library to use the virtualization capabilities of Red Hat Enterprise Linux.
These packages were previously shipped within the libvirt packages.

This update fixes the following bug:

• The block copy operation has previously been adjusted to change the disk type

of the copied disk to "file". However, using block copy for moving block-based
storage thus converted the new target to an incorrect type. Consequently, if a
virtual disk was backed by a block device rather than a file, libvirt did not
report the allocation information necessary to track a thin-provisioned volume.
This update introduces a libvirt flag that makes it possible to specify that the
target will be treated as a block device. As a result, users can now perform a
block copy to a block target correctly. (BZ#1196067)

Users of libvirt-python are advised to upgrade to these updated packages, which
fix this bug.
